2A14
2A14 aluminum alloy is a hard aluminum alloy, and the old brand is LD10. 2A14 contains higher copper content, higher strength, and thermal strength
It has good machinability, good resistivity, spot welding and seam welding properties, can be strengthened by heat treatment, and has extrusion effect.
Yes, but there are differences in vertical and horizontal performance. The corrosion resistance is not very good, and intergranular corrosion will occur during artificial aging.Corrosion tendency and stress corrosion cracking tendency.
