2011 aluminum pipe
The 2011 aluminum alloy material belongs to aluminum and copper alloy. Among all aluminum alloy products, because of the addition of Bi elements, it is the most free -cut alloy product. In the 2011 medium -intensity products, the material of the T3 state can provide excellent deep processing performance when smaller strength. If high -intensity products, T8 status materials should be selected. 2011 has excellent processability and high productivity for using processing on automatic lathes. Basically there is no need to use dandruff separators. As the most free -cut product in aluminum alloy, the 2011 mechanical processing performance level is A. The chips of the processing products are very small, the cutting surface has a self -cleaning function, and the vehicle parts are excellent. Widely used in hardware mechanical parts, automotive oil circuit system accessories, clock parts, gears, pipelines, audio -visual transition joints
Use
