Alloy 5754 is a typical aluminium-magnesium alloy which is closely related to the alloys 5454 and has higher strength than 5251. The most common tempers for 5754 aluminium are shown as O, H22, H24, H26, H32, H111 and etc. This alloy has excellent corrosion resistance especially to seawater and industrially polluted atmospheres. In particular, mechanical property requirements vary widely with temper, product and product dimensions. haomei aluminium specializes in 5754 aluminum plate and sheet since 1997 so that has a wide range of sizes available to fully satisfy customer’s requirement. We offers Alloy 5754 which corresponds to ASTM B 209, EN 485-2, EN 573-3, EN 754-2 standard designations and specifications but may not be a direct equivalen

0.8-mm-thick alclad 2024-T4 aluminum alloy sheets were friction stir butt welded. A 15-mm diameter shoulder tool was used to guarantee sufficient heat input during welding. A 0.08-mm shoulder plunge depth was adopted to reduce sheet thickness reduction. Sound joints were obtained at rotating speeds from 400 to 1000 rpm and welding speeds from 50 to 150 mm/min. A thickness reduction of 6% was achieved at 1000 rpm and 50 mm/min. Secondary phases firstly precipitated at the black lines in the stir zone (SZ). The hardness of the SZ showed a decrease about 6% compared with the base metal. A maximum tensile strength of 399.5 MPa and an elongation of 5.6% were achieved at 1000 rpm and 150 mm/min. The fracture morphologies showed typical ductile fracture mode.

aluminum sheet Thickness of aluminum plate is put under more than 0.2 mm to 500 mm and 200 mm width, length less than 16 m aluminum material as aluminum plate or aluminium material, below 0.2 mm for aluminum, article within 200 mm width of row materials or materials (of course with the progress of large equipment, the most can do 600 mm wide row material also more). Aluminum plate is the rectangular plate made of aluminum ingot, which is divided into pure aluminium plate, alloy aluminum plate, thin aluminum plate, medium thickness aluminium plate, decorative
Aluminium foil (or aluminum foil), often referred to with the misnomer tin foil, is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly http://used.In the United States, foils are commonly gauged in thousandths of an inch or mils. Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated to other materials such as plastics or paper to make them more useful.

Friction stir welding of thin 1050 aluminum sheet by heat assisted tool |

The objective of the present study is to relieve the friction stir welding (FSW) tool from one of its main role: to generate heat by friction. 1-mm-thick 1050-H24 aluminum sheets were friction stir welded using a heater-embedded FSW tool. It is demonstrated that butt welding of the sheets becomes successful even at a low rotational speed of 60 rpm under the assist-heating of the FSW tool. The fact indicates that it is possible to weld without frictional heat. Sound joints with the highest average fracture strength, which is equivalent to that of the base metal, was obtained under the welding speed of 0.5 mm/s and the tool rotational speed of 60 rpm. The temperature of the sheet does not exceed 400 K throughout the welding under this condition. This temperature is 60 K lower than the ordinary FSW in which assist-heating is not used. One of the microstructural features in heat-assisted FSW is that the widths of heat affected zone (HAZ) and thermo-mechanically affected zone are suppressed, compared to the ordinary FSW. Particularly, HAZ becomes almost negligible. The hardness profile shows the maximum at the stir zone without revealing HAZ softening.

Mirror polishing thin aluminum sheet on both sides without warping |
Posted by: KamorkasOa - 08-16-2018, 01:52 AM - Forum: Knowledge & Technique

Hello all,
We're trying to find a solution to achieve the same degree of standard grade mirror polishing on both sides of some rectangular pieces of 1 mm thick aluminium sheet, whilst retaining the flatness of the sheets.
The largest piece is 1500 mm x 300 mm (5 ft x 1 ft)
These will be components for an artwork we're trying to make, so lightness of material is imperative, hence aluminium.
The samples we received from the local polishers were bent from stress relieving as they were made from one-sided mill finished mirror-polished aluminium which was then shop polished on the reverse side.
Your thoughts would be appreciated - is electropolishing an option?

Density of Aluminum and the Thickness of A thin Aluminum Sheet |

Density is a property of a substance thus it can be used to identify a particular substance (Jensen 45). Density is a measure of how tightly packed particles are in matter by using the ration of mass to volume; mass and volume are related direct proportion (Mahan 20, Kalpakjian and scmid 13). Density is determined using the formula:
Where M is the mass while V is the volume
In this experiment, the masses and volumes of 3 samples of aluminum will be determined and be used to determine the density of aluminum. The density of the aluminum will be used to determine the thickness of the aluminum foil in the second part of the experiment.
Materials
Scale/balance
3 aluminum samples
25ml graduated cylinder
Caliper
Weighing boats
Procedure
3 aluminum samples were obtained: 1 aluminum shot and 2 aluminum bars
The scale was zeroed
The sample was placed on the weighing scale and the mass was recorded
The volume of the bar was determined using the formula Length (L)*Width (W)*Height (H) measured using a caliper
The volume of the shot was determine using the water displacement method
The volume of the second bar was determined using the L*W*H method
The value of the density of the 3 samples was calculated using the formula:
The value of the densities was then averaged.

Part II
Background
In science we use both large and small numbers at the same time. The laboratory tools available are not suitable for measuring the thickness of an aluminum foil. However, the volume of a regular object can be calculated using the formula:
Taking the height (h) to be the thickness (T) of the foil, therefore:
Using the density formula we get the volume formula
The aluminum foil can be measured to get its mass and used the density obtained from part I.
Materials
Balance, centimeter ruler, 4 sheets of aluminum foil, data table and a calculator
Procedure
A data table was made to include all the necessary data
A large aluminum foil was cut into 4 pieces with 900 edges
The length and width of each piece was measured and recorded
The mass of each piece was measured and recorded
Calculations were made

I have zero knowledge about welding aluminum. I'm only talking about being able to weld some thin sheet aluminum together to make a cup holder for my boy's motorcycles. I also want to be able to weld together some aluminum tubing to make a luggage rack.
Now...before you start trying to have me spend $2K on a welder.....Remember, I only want to do this for a few pieces and see if I like doing this. Isn't there a way to "weld" aluminum by applying heat and using a "welding rod"?? Educate me.!

Wrought Aluminium Alloys vs Cast Aluminum Alloys |
Posted by: KamorkasOa - 08-15-2018, 07:06 AM - Forum: Knowledge & Technique

It is simply to divide aluminum and aluminum alloys into two categories: wrought aluminium alloys and cast aluminum alloys. Wrought aluminium alloys contain lower percentage of elements, about less than 4%. Cast aluminum alloys contain the same chemical composition but has greater amounts. In the same temperature range( 520 to 590℃), the cast aluminum alloys undergo a thoroughly chemical properties while wrought aluminum alloys still remain the mechanical properties and remain ductile.
Aluminum plate advantages:
According to the rolling processing technique, cast aluminum alloys are generally divided into cold casting and hot casting aluminum alloy. The key difference is the recrystallization temperature.
Aluminium Alloy Grades
Aluminum alloy grates are the most basic types of aluminium sheets. According to international alloy designation system, there are mainly 8 aluminum alloy series .
1000, 4000 and 5000 aluminium alloy series are non-heat-treatable while 2000, 6000, 7000 and 8000 aluminium alloy series are heat-treatable. 8 series aluminum alloy sheet has different advantages: series 1000 alu sheet is pure industrial aluminum alloy and is lower in prices; series 3000 alu sheet is the most great type on corrosion resistance and also being called “corrosion resisting aluminum alloy”; series 2000 and 7000 alu sheet are aluminium alloy used in aircraft; 8011 alu sheet is the best aluminum foil material.
In haomei Aluminum, our main types of aluminium sheets are series 1000, 3000 and 8011. Mature means of processing and casting is the quality of haomei Aluminum aluminum sheet plate. According to your practical application, our professional staff will make a more elaborate division for you.
