Home > Application Area > Aluminum alloy material

Aluminum alloy is divided into 1 series -9 Series.
1-Series: Features: More than 99.00% of aluminum, There are good electrical conductivity, Good corrosion resistance, Excellent weldability, low strength, heat-strengthened. Applied range: 99.9% per cent of the amount of high-purity aluminum (al) is mainly used for scientific experiment, the chemical industry and for special purposes.
2-Series: feature:: the aluminium alloy containing copper as the main element. Will the addition of Mn, Mg, Pb and Bi in order to machinability.
Such as: alloy 2011, we should pay attention to the security protection in the process of smelting (produces toxic gases).
Alloy 2014 with the aviation industry, and high strength.
2017 Alloy intensity a bit lower than that of 2014 alloy, but it is easier to work.
2014 Treatable.
Faults: severe intergranular corrosion.
Scope of application: aviation industry (2014), the use of screw (2011) and high temperature (2017).
3: Characteristics: the main alloying elements Mn aluminum alloy, non-heat treatment, the corrosion resistance good welding performance is good.
Good plasticity.
(Near super aluminum alloy).
Disadvantages: low strength, but through the strengthening of cold-hardening strength.
Annealing is easy to produce coarse grains.
Scope of application: used on aircraft oil seamless tubes (3003), cans (3004).
4-Series: silicon-based, not commonly used.
Section 4 is treatable, but there are also some 4 of non-heat-treatable alloys.
5 system: characteristics: magnesium.
Resistance of patience and good welding performance, fatigue strength, and non-heat treatment, can improve the strength of cold.
Scope of application: the handle of a lawn mower, aircraft fuel tank vessel, a vest.
6 Departments: the characteristics of magnesium and silicon-based.
Mg2Si for the main strengthening phase, currently the most widely used alloy.
6063, The maximum number of 6061, 6082, 6160, 6125, 6262, 6060, 6005, 6463.
6063, 6060, 6463 In 6 is relatively low in strength.
6262, 6005, 6082, 6061 And 6 higher in strength.
Characteristics: medium strength, good corrosion resistance, excellent weldability, good performance (ease of extrusion molding) good performance of oxidation coloring.
Scope of application: hand tools (such as: car rack, doors, windows, body, heat sink, the inter-box shell).
7: Characteristics: zinc, but sometimes also to the addition of a small amount of magnesium, copper.
These super-hard aluminum alloy is containing zinc, lead, magnesium, and copper-alloy close to the hardness of the steel.
The slow extrusion speed higher than that of 6 alloy, the welding performance well.
7005 And 7075 are the highest in the 7 grade, can be intensified.
Scope of application: the load-bearing component in Aviation (aircraft, the landing gear), rocket propeller, aviation spacecraft.
