Alloy aluminum plates are made by adding a variety of alloying elements (mainly copper, silicon, magnesium, zinc, manganese, and small amounts of alloying elements such as nickel, iron, titanium, chromium, lithium, etc.) to increase the mechanical properties and chemical indicators of the aluminum plate. . Alloy aluminum plates have some specific properties that pure aluminum plates do not have, and are widely used in specific environments such as ships, refrigerators, molds, and aerospace equipment.
1. Alloy aluminum plates can be divided into: according to the main alloy elements:
Aluminum-copper alloy aluminum plate (Al--Cu)
Represents 2A16 (ly16), 2A06 (ly6). This series of aluminum plates is characterized by high hardness, with a high raw copper content of about 3-5%. This series of aluminum plates are aviation aluminum materials and are currently not widely used in traditional industries. Currently, there are not many factories producing this series of aluminum plates in the market. With the development of the aerospace industry, the production skills of this series of aluminum plates will further increase.
Aluminum-manganese alloy aluminum plate (Al--Mn)
Mainly represents 3003 aluminum plate, 3004 aluminum plate, 3A21 aluminum plate, which can also be called anti-rust aluminum plate. The production technology of this series of aluminum plates in our market is excellent. This series of aluminum plates is mainly composed of manganese, with a content ranging from 1.0% to 1.5%. It is a series of products with good anti-rust properties and is commonly used in air conditioners, refrigerators, and automobiles. It is a more commonly used alloy series in humid environments such as the bottom.
Aluminum-silicon alloy aluminum plate (Al--Si)
The representative is 4A01, which belongs to the series with high silicon content. Usually the silicon content is between 4.5% and 6.0%. It belongs to building materials, mechanical parts, forging materials, and welding materials. It has low melting point and good corrosion resistance. Product description: It has good corrosion resistance. Characteristics of heat and grinding.
Aluminum-magnesium alloy aluminum plate (Al--Mg)
Represents 5052 aluminum plate, 5005 aluminum plate, 5083 aluminum plate, 5A05 aluminum plate series. This series of aluminum plates belongs to the more commonly used alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3 and 5%. It can also be called aluminum-magnesium alloy. Its main characteristics are low density, high tensile strength and high elongation. In the same area, the weight of aluminum-magnesium alloy is lighter than other series, so it is often used in the aviation field, such as aircraft fuel tanks. It is also widely used in traditional Industrial, the processing technology is continuous casting and rolling, it belongs to the hot-rolled aluminum plate series, and can be oxidized and deeply processed. This series of aluminum plates is one of the more mature aluminum plate series in our market.
Aluminum magnesium silicon alloy aluminum plate (AL--Mg--Si)
Represents 6061 aluminum plate and 6063 aluminum plate. It mainly contains magnesium and silicon. 6061 is a cold-treated aluminum forged product. It is suitable for areas requiring high corrosion resistance and oxidation resistance. It has good usability, excellent interface characteristics, easy coating and processability. , it can be used on low-voltage machines and aircraft joints.
The general characteristics of 6061: excellent interface properties, easy coating, high strength, good usability, and good corrosion resistance. Typical uses: aircraft parts, camera parts, couplers, ship parts and hardware, electronic parts and connectors, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical accessories, valves and valve parts.
Aluminum-zinc alloy aluminum plate [AL--Zn--Mg--(Cu)]
Represents 7075, mainly containing zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy and a heat-treated alloy. It is a relatively hard aluminum alloy and has good wearability. The 7075 aluminum plate will not deform or warp after stress removal. The entire plate is too large and too thick. 7075 aluminum plates are all tested using sonic waves to ensure that they are free of blisters and impurities. 7075 aluminum plates have high thermal conductivity and short molding time, which increases work efficiency. Its main feature is that the hardness of 7075 is an aluminum alloy with high hardness and high strength, which is often used in aircraft manufacturing.
2. Alloy aluminum plates can be divided into heat treatment strengthened alloy aluminum plates and non-heat treatment strengthened alloy aluminum plates according to whether they can be strengthened by heat treatment. The latter can only be strengthened by cold working but not by heat treatment.
3. Alloy aluminum plates can be divided into binary alloy aluminum plates, ternary alloy aluminum plates, quaternary alloy aluminum plates and multi-element alloy aluminum plates according to element units.
