When is copper sleeve used best?
- Jun 13, 2017 -

Copper covers are characterized by high hardness, high wear resistance, corrosion resistance, then you know that copper sleeve under what circumstances, the use of the best effect?

  1. copper sheath should be used after heat treatment, because of the strength of copper, especially plastic and toughness decreased. The copper sheath must be normalized or annealed in order to refine grain, organize evenly and eliminate internal stress. After normalizing the copper, the performance of the machine after annealing has also become lower because of its high cost, so it is widely used. However, normalizing treatment resulted in relatively large internal forces for annealing, only for copper parts with a carbon content of 0.35%.

2. low carbon copper pieces, good plasticity, easy to break when cooled. Internal force becomes smaller, copper sheet normalization, should also be high temperature tempering. Complex structures and copper parts that are prone to cracks can only be carried out by annealing. Copper parts should not be quenched, otherwise it is easy to crack.

I hope to help you by reading the above.
