what happens to the mechanical properties of copper?
describe the mechanical properties of copper in the same conditions extrusion and how to change the bending properties of copper tubing?
When copper is extruded, it is difficult to work mainly in the longitudinal direction (length) address. This greatly increases (increases the yield and ultimate strength), but less ductile. If you want make copper turns, you always possible, but the risk of failure if you exceed the limit of elastic deformation. To avoid this, you anneal copper (from heat at the recrystallization temperature for at least 10 minutes, then let it cool slowly enough).
