The characteristics of 2A12 aluminium alloy are: high strength, certain heat resistance, and can be used as working parts below 150 degree C. The strength of 2000 series alloys is higher than that of 7075 aluminium alloys when the temperature is higher than 125 degree C. The formability is better in hot state, annealing and new quenching state, and the heat treatment strengthening effect is remarkable, but the heat treatment process is strict. Corrosion resistance is poor, but pure aluminium coating can be effectively protected. Cracks are easy to occur during welding, but special technology can be used to weld or rivet. Widely used in aircraft structure, rivets, truck wheels.
Aluminum-copper-magnesium is moderate. Typical hard aluminium alloy is 2A12 aluminium plate. Its alloy composition is reasonable and its comprehensive performance is good. More and more countries around the world have begun to produce 2A12 aluminium sheet. In the global consumption of hard aluminium, 2A12 aluminium sheet is also the largest.
The use of aluminum sheet plate is so wide that it can achieve high hardness, corrosion resistance and easy installation through a certain process treatment. It is very suitable for the production requirements of machinery manufacturing industry. More and more aluminum products manufacturers begin to use 2A12 aluminum sheet as their raw material. In the near future, 2A12 aluminum sheet will be more popular.
