Pure aluminum 1 series
Features: 99.00% or more of aluminum has good electrical conductivity, good corrosion resistance and good welding performance.
Low strength, no heat treatment strengthening. Application range: from pure aluminum (including aluminum 99.9%
Top) Mainly used in scientific experiments, chemical industry and special purposes.
Aluminum alloy 2 series
Features: Aluminum alloy with copper as the main element. It also adds manganese, magnesium, lead and
Oh, for machinability. Such as: 2011 alloy, pay attention to safety during the melting process
Protection (will produce harmful gases. 2014 alloy used in the aviation industry, strength away.
The 2017 alloy is a little weaker than the 2014 alloy, but it is more suitable for processing. 2014 can
Heat treatment strengthening. Disadvantages: The tendency of intergranular corrosion is serious. Applications: Aviation industry
(2014 Alloy I, Screws (2011 Alloy) and industries with higher operating temperatures<
Aluminum alloy 3 series
Features: Aluminum alloy with manganese as the main alloying element, can not be heat treated and strengthened, resistant to corrosion
Good etch performance and good welding performance. Good plasticity. (close to super aluminum alloy I. Disadvantages
: Low strength, but can be strengthened by cold work hardening. Easy to produce during annealing
Raw coarse grains. Scope of application: Oil-conducting seamless pipe used on aircraft (3003
Gold > , cans (3004 alloy >.
Aluminum alloy 5 series
Features: The main element is magnesium, and the magnesium content is between 3-5%. Aluminum and magnesium
alloy. The main features are low density, high tensile strength and high elongation. . Resist
Good performance, good welding performance, good fatigue strength, no heat treatment strengthening, only cold
Processing increases strength.
Aluminum alloy 6 series
Features: mainly based on magnesium and silicon. Mg2Si is the main strengthening phase and is currently the most widely used.
Alloy. 6063 and 6061 are the most used, and 6061 is relatively strong in the 6 series.
The middle end of the Cyclone No. 2 is the 6061 characteristic: medium strength, corrosion resistance
Good, good welding performance, good process performance (easy extrusion), gasification coloration
Can be good. Applications: Energy tools (eg car luggage racks, doors, windows, body)
, heat sink, compartment case)
Aluminum alloy 7 series
Features: mainly zinc, but sometimes a small amount of magnesium, copper. Super hard aluminum
The alloy is the hardness of zinc, lead, magnesium and copper alloys close to the steel. Squeeze speed
The degree is slower than that of the 6-series alloy and the welding performance is good.
