Significance of copper heat treatment

In fact, pure copper cannot be heat treated because it has no isomeric change at high temperature. And when you say heat treatment, you should mean heat treatment of copper alloy. Brass is the most common hot working in copper alloys, that is, copper alloys with zinc as the main element. That is to say, the heat treatment with zinc content between 38% and 47% is similar to the heat treatment of steel, that is to say, the internal stress is reduced, segregation is eliminated, the plastic toughness is improved, and the strength and hardness are appropriately reduced, thus improving the comprehensive mechanical properties of copper.
