Aluminum sheet, as the name suggests, refers to the material made of aluminum or aluminum alloy material. Or is the type of aluminum products by flat aluminum embryo through heating, rolling and straightening or solution and aging process made.
Aluminum building used include monolayer sheet, composite aluminum and other materials, usually often refers to aluminium (also called the single pure aluminum or aluminum), used for building decoration engineering, in recent years in the use of aluminum single aluminum sheet curtain wall is more common. Aluminum sheet curtain wall is also a form of curtain wall. In brief, it is made of aluminum sheet instead of glass, and aluminum curtain wall is used as wall protection and lighting wall. Such as the world trade center in Guangzhou, with the aluminium processing factory factory processing sheet in different sheet radian of nearly one hundred and fifty tons, the surface of the electrostatic spray. Single layer aluminum sheet has been used in foreign aluminum curtain wall. Single aluminium sheet is usually made of pure aluminium sheet. sheet thickness is 3mm, in order to strengthen the strength of aluminum sheet, aluminum sheet in the back, must reinforcement installation (existing manufacturers uneasy), reinforcing ribs made of thick aluminum strip, first with a screw cap to flash butt welding in aluminum back and then made reinforced aluminum strip drilling into the screw. Fixed by screws.
In order to lighten the weight of aluminum sheet and increase the strength of aluminium sheet, we use aluminium alloy sheet, often use No. 21 antirust aluminium, code No. LF21 pressed aluminum sheet as curtain wall aluminium sheet. The thickness of the aluminum sheet is reduced from 3mm to 2.5mm, and the strength of the alloy is about twice higher than that of the pure aluminum sheet. The reinforcing ribs are made of LF21 aluminium strip, and the width and thickness of the aluminium strip are determined according to the surface of the aluminum sheet. The thickness of the aluminum strip is generally 2-2.5mm and 10-25mm wide. Why should the back of aluminum curtain wall sheet Angus reinforcing bar in the outside world is positive and negative pressure, a sheet will not sag, not two bulge vibration sound so as to avoid the repeated vibration and aluminum curtain wall inside and outside a. If sound insulation is necessary, place rock wool, slag wool or foam on the inside of the aluminum sheet. The first domestic production of aluminum curtain wall aluminum factory, deep processing factory in Chongqing factory for the SWA, military manufacturers, production of aluminum sheet width can reach 2.8 meters. Curtain wall aluminum sheet surface treatment can be divided into two methods, one is anodic oxidation, and the other is electrostatic spraying. Anodic oxidation film in general more than 12 mu, only the bronze color and white two colors, monotonous, more serious shortcoming is the color depth of each aluminum sheet curtain wall , many blocks are combined together to form the overall effect of a curtain wall is very ugly. This drawback can be said that can not be eliminated, is not caused by the production technology, but because of aluminum is not by a lot, the chemical composition, have small differences, coupled with the oxidation of factors of electrolysis bath and current density are not exactly the same, so the number of oxidized color difference, single look may not be obvious, if together is very obvious. Therefore, the aluminum curtain wall aluminum sheet surface treatment must not be anodized.

What is stretching aluminum:
Stretching aluminum is made of aluminum after drawing aluminum and aluminum parts.
Which grade aluminum sheet and what state stretch the best:
From the aluminum sheet grade, the 1 series aluminum sheet 1060 aluminum sheet, 1070 aluminum sheet, 1100 aluminum sheet suitable for stretching, 5 series aluminum sheet 5052 aluminum sheet is also appropriate; from the aluminum processing state, O-state aluminum sheet is the softest, no hardness, the most suitable stretch , So 1 series O state, 5 series O state aluminum sheet to do the most appropriate aluminum sheet. In the case of
Stretch the aluminum sheet can not be too hard, too hard will pull the explosion, the tensile properties of aluminum as low carbon steel, stretching is very easy to pull the broken, so the elongation of aluminum and tensile strength Height and stretch will have different requests.

Aluminum and other materials have a very broad consumer market, benefit from the excellent performance of aluminum, many industries will be aluminum as a substitute for traditional metal materials, especially in recent years, aluminum production, sales are growing rapidly, huge Business opportunities to attract countless gold rush to join, so a variety of aluminum blossom everywhere, many of them are no strength, no qualified. They use the convenience of the Internet to mislead customers, sold to customers unqualified products. So, in so many aluminum manufacturers, how should choose a formal, rest assured that the manufacturers do?
1, whether the three card
Business license, the organization code certificate, tax registration certificate, commonly known as the enterprise three card. In the choice of aluminum manufacturers, consumers should take the initiative to ask the enterprise documents are complete, the name is consistent, which is to determine whether the formal aluminum manufacturers the most intuitive way.
2, registered capital
Aluminum manufacturers can be intuitive from the strength of the registered capital of the enterprise, a registered capital of 10 million of the enterprise strength is much higher than a registered capital of only 300,000 enterprises.
3, operating time
Although the length of business time and aluminum manufacturers are strong, formal and no direct contact, but a business in the industry for more than 10 years of business in the certainly certainly higher than the newly established new company.
4, the number of stocks
Aluminum manufacturers and more to spot-based business, as a capital-intensive industries, aluminum manufacturers inventory of aluminum spot the number of manufacturers is the strength of the most intuitive proof. An inventory of more than 1,000 tons of enterprises and stocks less than 100 tons of enterprises compared to the natural tonnage more trustworthy.
5, customer reputation
As the saying goes, the Gold Cup Silver Cup as the reputation of customers, aluminum manufacturers are formal integrity, you can go to the peer to inquire about a no one heard, or generally not high evaluation of the enterprise, in the cooperation naturally be careful.

Henan is one of the aluminum processing industry gathering place, Henan aluminum manufacturers are numerous, all companies have differences in the quotations of aluminum, the buyer will be confused after consulting multiple manufacturers, the same alloy product prices how the gap is so large, the following reasons several aspects:
1, the price of aluminum ignot: Aluminum prices are mainly aluminum ingot prices and processing costs of two parts, with the same material with the state processing fee is relatively fixed specifications, aluminum ingot prices fluctuate greatly affected by the market, so the aluminum prices fluctuate accordingly.
2, Dofferent materials affect the price of aluminum price:1 Series, 3 Series process is relatively simple, less difficult to produce, aluminum manufacturers and more, the price is relatively low, while the 7 Series, 5A05 and other brands are relatively high.
3, the commonly used specifications low price, special specifications aluminum prices higher
4, brand influence. Brand awareness, imported brands, domestic first-line well-known brands, due to excellent quality, customer trust, scarcity of sources, the relative price of aluminum is higher, which is also asking buyers around asking, the same material, different manufacturers offer large differences.
5, In addition, the number of orders, transport distance and other factors also have a greater impact on the price of aluminum.
Henan haomei Aluminum is a listed company, the company diversified products, complete specifications and reasonable price, customer service. In order to meet the different needs of customers, prompt deliver.

The quality of food is connect with its packaging, and let's see how to distinguish the quality of aluminum foil bags.
![[Image: templatemo_image_01.jpg]](http://www.aluminium-foils-cn.com/images/templatemo_image_01.jpg)
1. The printing quality of aluminum foil bags.
You can observe the junction of foil bags to see if it has any obvious third color, brushed, matte surface or missing printed.
2. The material of aluminum foil bags.
The foil bags must be odorless, people always feel a bag with some smell does not meet the health standards. If foil bags are odorless, we also need to check the transparency.
3. The firmness of aluminum foil bags.
The firmness level of aluminum foil bags without tin ingredient is different because of it material. The main method for distinguish is use our hands to tear the edge of the bags. A composite bag that made of nylon and high-pressure film is hard to tear by hands, so this kind of bag can used for bagging some heavier products, like stone, large particles and so on. On the contrary, the bag which made of OPP heat sealing film is easy to tear, but it can bagging some light weight products only. We can observe the shape and structure of section after tearing the bag, if the section is evenly from middle of heat seal, it shows this bag will easy to break during production process; if the section tore from sealing place, it shows the quality of heat seal is better. We also can check compound firmness by the structure of crack, if we can apart this several layers easily, it indicates that the compound firmness is good. In addition, we also check the surface has any air bubbles or wrinkles.
4. The tidiness of appearance.
Check the stiffness. In general, the higher stiffness the better quality bag is, but it depends on material and requirement. For example, the composite bag that made of nylon and high-pressure film, there will have some wavy shapes in heat seal; as well as check the edge of bags whether it is neat or not.

Only to do a good job on the maintenance of the aluminum alloy coil in daily life can ensure its efficient use. Aluminum alloy coil is our main product, and it has a wide application of building. We need to pay attention to the maintenance of aluminum coil because of it easy to oxidize.
Maintenance works:
1. Must be covered with tarpaulin to prevent the intrusion from rainwater and snow during shipping.
2. Must ensure the oxide film and paint film of sheet surface remained intact,
3. Storage environment should be dry, bright, well-ventilated, no corrosion of the climate.
4. In storage, Must be separated aluminum coil from the ground with rails tie plate for moistureproof, keep the distance to the ground more than 10CM.
5. Do not store with chemical materials and moisture materials
6. After processing into doors or windows, need to clean regularly with net cloth.
The performance of aluminum alloy coil:
1. Mechanicalness, aluminum alloy coil use the good quality aluminum material, plastic and adhesive, and a advanced composite technology. The product has the flexural strength that decorative panels requires, will not mbending, deforming, inflating with the change of wind pressure, temperature, humidity and other factors.
2. Flat surface, there are no composite indentation on surface, no residual stress on the board and do no deformed after shearing.
3. Weatherproof, the paint pattern that backing by coated and high temperature has a high gloss retention and a stable tint. The polyester paint warrant 10 years, and the fluorocarbon paint warrant more than 20 years.
4. Environmentally friendly, will not be corroded by salty acid rain, do not release any toxic gas, the keels and fasteners will not be corroded.
5. Decorative, it can coating into wood grain or stone pattern, has a rich texture and natural beauty.

061 aluminum plate is the most commonly used 6000 series aluminum plate products, are aluminum and magnesium silicon alloy, the most commonly used are T6 state, T5 state and other states in the market , then what is the difference between 6061T6 aluminum alloy and 6061T5 aluminum alloy?
First of all, in the production process, 2000 series,6000 series,7000 series of aluminum plate products can be quenched to improve the strength of aluminum plate. What is the meaning of quenching? It is the alloy aluminum plate products heated to a certain temperature, then after a sudden cooling, in order to achieve the required hardness of the product. This is the T5 state and T6 state all needed to go through the process. The difference is that the 6061T6 aluminum plate refers to the aluminum plate to reach the high temperature instantly water cooling, so that the aluminum plate to achieve the required hardness. But T5 state is after high temperature then the use of air-cooled rapid cooling to achieve the required hardness. From the time point of view, T6 state water is cooling, that is, artificial aging time is shorter, but T5 state air-cooled natural aging time requires 2-3 days. But in the application, T6 state hardness higher than the T5 state, the price per ton should also increase about 800 RMB.
In addition, the market commonly used 6061T651, which need to add a stretch process. Because the T651 state is often used by customers to bend, deep punch and other follow-up processing, so when the aluminum plate in hot extrusion in production of the internal energy must be stretch fully released, if not released, may later produce aluminum surface bending, wave and so on.
