The 5052 aluminum plates that are used daily are purchased directly from the manufacturers, so that the wholesale quantity can be guaranteed, the price is also very favorable, and the quality of the products does not need us to worry. However, the price of aluminum sheets produced by different manufacturers will vary greatly. For wholesalers, a slight price difference will have a particularly large impact. Naturally, it is necessary to make a comprehensive comparison of prices. What are the factors?
5052 aluminum plate manufacturer - Mingtai Aluminum
Factor one, the impact of quality on price. As long as the quality of the 5052 aluminum plate is good, the price is generally around the average price of the market. The cost price of this type of aluminum plate is relatively close, so there will be no ultra-low price on the market price. If we want to wholesale and cooperate directly with the manufacturers, then it is naturally the cheapest to enjoy the ex-factory price of the market. However, if the quality is slightly worse, or the materials are generally used, the price seems to be lower, but the actual use effect will be affected, or it is recommended that everyone consider it clearly.
Factor two, the impact of wholesale quantity on prices. The number of wholesale 5052 aluminum plates will also have a certain impact on product prices. Manufacturers will have a minimum requirement for wholesale quantities. If the wholesale quantity is more, the price will definitely be more favorable. Wholesale directly cooperates with the manufacturer to understand the wholesale price of the manufacturer, and it will also help us to purchase later.

| How To Degrease Zinc And Aluminum Die Castings |
|

Zn-al die casting is a kind of powder die casting parts with zinc as the main component. The surface of this part is a very dense layer, inside is a dispersed porous structure. Instead of using an acidic degreaser, only an alkaline degreaser can be used for degreasing.
Most zinc-aluminum parts require copper-nickel-chromium multilayer coating, which has higher requirements for decoration. It is mechanically polished before degreasing. So waxing (the waxing cream is rich in white wax) is a step forward, followed by chemical degreasing and electrolytic degreasing.
Because the melting point of white wax is above 70%, in order to emulsify white wax, dewaxing water temperature above 70℃ is useful. In the past, we only used ordinary chemical degreasing liquid to remove wax. This method has long time and low power. Now there is a special wax removal water supply, time to shorten, the effect is better. If apply ultrasonic effect very good. Usually wax removal water only wax removal without degreasing, but also chemical degreasing. The chemical activity of zinc alloy is very strong, the alkalinity of chemical degreasing liquid should not be too strong, or it will corrode the appearance. The temperature is usually controlled between 50 and 70℃ for 3 to 5 minutes. The product that supplies on the market also has the degreasing agent that combines degreasing and removing wax for one, cooperate ultrasonic effect very good.
The composition of electrolytic degreaser of zinc alloy is similar to that of chemical degreaser. But it is necessary to enrich the complex agent ability to use. In electrolytic degreasing, zinc alloy die casting parts should be placed in cathodic degreasing, temperature 50 ~ 70℃, current density 3 ~ 5A/dm2, time 1 ~ 2min.
When selecting the two-in-one process of wax removal and degreasing, brown corroded film will sometimes occur on the surface of casting under ultrasonic effect. This degreasing agent should not be used. Degreasing agents for zinc die castings should be replaced. Special attention should be paid to this.

Aluminum, our daily industrial raw materials called aluminum ingots, according to the national standard (GB/ t1196-93) should be called "remelting aluminum ingots", but we used to call "aluminum ingots". It is produced by electrolysis of alumina and cryolite. There are two kinds of aluminum ingots after they are used in industry: forged aluminum alloy and deformed aluminum alloy. Wrought aluminium and aluminium alloys are castings produced by forging; Deformation of aluminum and aluminum alloy is produced by pressure processing of aluminum processing products: plate, tape, foil, pipe, bar, type, wire and forging. According to the national specification of remelting aluminum ingots, "remelting aluminum ingots are divided into 6 trademarks according to their chemical composition, namely Al99.85, Al99.80, Al99.70, Al99.60, Al99.50 and Al99.00" (note: the number after Al is aluminum content). At present, some people call "A00" aluminum, in fact, aluminum containing 99.7% purity, in the London market called "standard aluminum". As we all know, in the 1950s, China's technical specifications were all from the former Soviet union, and "A00" was the Russian trademark in the national specifications of the Soviet union. With the word of world line, say "normative aluminium" more appropriate. Standard aluminium is aluminium ingots containing 99.7 per cent aluminium and is registered on the London market.

| What is the best filler alloy for 5083 base alloy? |
|
Posted by: Keganhirl - 07-10-2019, 09:17 AM - Forum: aluminium faq

[ltr]Base alloy 5083 can be successfully welded with filler alloys 5356, 5183, or 5556, any of these three filler alloys may be suitable for welding this base alloy. The reason to choose one of these filler alloys over the others is dependant on the application and service requirements of the component being welded. Used in a number of applications, base alloy 5083 aids in shipbuilding, cryogenic tanks, military vehicles, structural fabrications, just to name a few. The 5356 filler is normally only used on 5083 base alloy when there is no requirement for groove weld welding procedure qualifications, in accordance with the structural welding code; this is because the 5083 base - 5356 filler combination will typically not obtain the minimum tensile strength requirements of the code (40ksi – 275MPa) for groove weld transverse tensile strength. The 5356 filler alloy is often used on the slightly lower strength 5086 base alloy and will typically obtain its required minimum transverse tensile strength for grove welds (35ksi – 240MPa). The 5183 and the 5556 filler alloys will both typically meet the code tensile strength requirements for groove welds in 5083 base alloy. Developed specifically for welding the 5083 base alloy, the 5183 filler meets the mechanical property requirements for groove weld procedure qualification. The 5556 base alloy, with slightly higher mechanical properties than the 5183, will meet the minimum requirements for the 5083 base alloy. The 5556 filler alloy was developed for obtaining slightly higher tensile strength requirements (42ksi – 285MPa) of groove welds in 5456 base alloy.[/ltr]
[ltr]In my opinion, the filler alloy selection is not the problem causing you to fail the guided bend tests; however, I do think you need to understand the application/welding standard requirements when selecting the most appropriate filler alloy.[/ltr]

| 11 Tips for Welding Aluminum in the Shipbuilding Industry |

Aluminum alloys are lightweight and corrosion-resistant in marine environments, making the superior material for use in the shipbuilding industry.
There are two aspects that make general aluminum welding different from welding steel in the shipbuilding industry, and both are related to the fact that much of the welding is performed outdoors: - Storage of aluminum plates and extrusions is critical to avoid oxidation
- Extra care must be taken to avoid breezes in the welding area
Both aspects will be discussed in more detail on the next few pages.
Know Which Aluminum Alloy You Are Welding
It isn’t enough to know that you are welding aluminum. Welding professionals have to know which alloy is about to be welded, and they have to know the correct filler metal to use. The most common alloys used in shipbuilding are the Al-Mg 5XXX sheet alloys and the Al-Mg-Si 6XXX extrusion alloys, primarily because of their excellent resistance to corrosion.
Most aluminum alloys are easily arc weldable. Virtually all of the alloys in the 1XXX, 3XXX, 4XXX, 5XXX and 6XXX series can be arc welded using GTAW and GMAW. However, most of the alloys in the 2XXX and 7XXX series cannot be arc welded. The only arc weldable alloys in the 2XXX series are 2219 and 2519. Almost all of the other 2XXX alloys will crack severely when welded. Similarly, the only alloys in the 7XXX family that can be arc welded are 7003, 7004, 7005 and 7039.
Specifically, be particularly wary of 2024 and 7075. It is tempting to buy one of these alloys for repair welding because they are strong and commonly available, but they are crack-sensitive to arc welding.
Welding an “unweldable" alloy or using the wrong filler alloy can result in immediate cracking or a premature failure in service at a later time.
When Should You Preheat?
Some people believe that all aluminum welds, both GTAW and GMAW, should be preheated. This isn’t true. In fact, if you have the correct equipment, preheat is rarely necessary.
Additionally, excessive preheat can severely degrade the mechanical properties. The last step in the heat treatment is aging, which is conducted at temperatures between 325 and 400°F. If you preheat to or above the aging temperature, you will ruin the alloy’s mechanical properties.
This is not to say that all preheating is bad. For example, if outside temperatures and humidity are very high, it is acceptable to preheat to 200°F to drive off moisture. Just don’t get carried away.
Storage of Aluminum Sheet, Plate and Extrusions
For most industries, the standard recommendation is to store aluminum inside prior to fabrication. While that is a good recommendation, it probably is unrealistic in the shipbuilding industry, where most welding is performed outside. There are more realistic storage recommendations for shipbuilding.
Make Sure You Clean the Parts Adequately Before Welding
Cleaning aluminum before welding consists of two separate and distinct operations. First, all oils, lubricants, machining coolants and other hydrocarbons used in manufacturing must be removed. Any hydrocarbons remaining on the material will get into the welding arc and release hydrogen gas, which causes weld porosity.
Removing hydrocarbons can be done in one of two ways. The most common is to wipe the plate with a clean rag saturated with a good degreasing solvent, such as acetone, toluene, MEK or carburetion cleaner. (Alcohols are not good degreasers and should not be used to clean aluminum.) Alternatively, but less common, the aluminum can be dipped into a tank containing a mild alkaline solution, then rinsed and dried.
Secondly, remove any heavy oxides from the aluminum before welding. This is normally done by hand or mechanically using a stainless steel wire brush. In cases where the materials are stored outside and develop a heavy gray oxide, it may be necessary to remove the oxide using a sanding or grinding disk.
Use the Correct Equipment
Before beginning each shift, welders should make sure the welding equipment is correctly set for aluminum. This is especially important if the equipment is interchangeably used to weld different materials.
Specifically for GMAW welding:
Make sure the spool brake is not set too tight. Excessive tension will cause wire feeding problems. The brake should just be tight enough so that the spool doesn’t freewheel when the wire is stopped.
Make sure the drive rolls are made for aluminum and have the correct diameter. Using V groove drive rolls, which are made to weld steel, on aluminum will deform the aluminum wire and cause feeding difficulties.
Set the drive roll tension only tight enough so that the drive rolls don’t slip on the wire. Excessive tension will cause the filler wire to deform.
Make sure the correct plastic inlet and outlet guide bushings are in place. Use of the steel parts used to feed steel wire will cause feeding problems.
Make sure the gun liner is the correct plastic material used for aluminum. Use of the helical steel gun liner typically used to feed steel wire will take small shavings off the soft aluminum wire and cause the liner to clog up.
Make sure the contact tip is the proper size for the aluminum wire being fed. Some people believe it is a good idea to use an oversized contact tip – for example, a 1/16-inch contact tip to feed 3/64-inch wire. DO NOT DO THIS. The tip must be of a size to freely pass the wire through but still tight enough to provide uniform electrical contact between the contact tip and wire. An oversized contact tip will not allow uniform current transfer, resulting in an excessive number of burnbacks.

| How to Refinish Aluminum Wheels With Clear Coat |
|
Posted by: Keganhirl - 07-10-2019, 08:53 AM - Forum: aluminium faq
- No Replies

Alloy wheels are stronger than steel wheels, and most receive a clear coat on top of the paint of natural finish that protects the wheels and gives them a more glossy appearance. Over time, the clear coat on a set of wheels begins to flake, fade or become scratched, particularly if the wheels are not properly cared for.
[size=3][size=4]Step 1
Remove the wheels from the vehicle if they are still installed. Loosen the lug nuts with a lug wrench. Lift the vehicle with a floor jack, support it on jack stands and then remove the wheels.[/size][/size]
[size=4]Step 2
Take the wheels and tires to a tire shop and have the tires removed from the wheels. Painting the wheels without the tires installed will produce better results since the tires will not have to be taped off while the wheels are painted. Skip steps 1 and 2 if there are no tires installed on the wheels.
[/size]
[size=4]Step 3
Strip the existing paint and clear coat from the wheels with paint stripper. Spray on the stripper using an aerosol-type stripper, or apply it with a paint brush if using a gel-type stripper. Allow the stripper to soak into the paint until it bubbles up, then wipe it off with a rag. Repeat until all of the old clear coat, paint and primer is removed.[/size]
[size=4]Step 4
Mask off any areas on the wheel that are not going to be painted with masking tape. For example, the outer rim on some wheels is polished and not painted. Wipe the entire wheel down with mineral spirits and a clean dry rag until all residue and oils are removed from the wheel.[/size]
[size=4]Step 5
Apply a light dusting of primer to the wheel. Let the primer dry for a minute or so, and then apply a heavy coat. Hold the can eight to 10 inches from the wheel, and move it back and forth in a smooth motion. To avoid runs, do not hold the can in one area. Allow the primer to dry according to the directions, then apply one or two more coats.[/size]
[size=4]Step 6
Allow the primer to fully dry, which will be at least an hour so. Wet sand the primer with 220-grit and then 320-grit sandpaper. Use plenty of water. Dry the wheel with a clean, dry rag, then wipe it down again with the mineral spirits.[/size]
[size=4]Step 7
Spray on a light dusting of the color of your choice. Allow the paint to dry for a minute, then apply a solid coat, spraying smoothly back and forth to avoid runs. Apply two to three coats or as many as give full color coverage, allowing sufficient drying time between coats.[/size]
[size=4]Step 8
Allow the paint to dry fully. Wet sand the wheels with 220-grit, 320-grit, 400-grit and then 600-grit sandpaper. Ensure that they surface of the wheel is smooth in all areas. Wipe the wheel down with the mineral spirits and a clean, dry rag.[/size]
[size=3][size=4]Apply two to three coats of clear coat, allowing sufficient drying time between coats. Allow the clear coat to dry overnight before attempting to reinstall the tires or reinstall the wheels back on the vehicle. Wash the wheels regularly with soap and water and a wheel brush to maintain the finish.[/size]
