OCC pure copper wire Ohno Continuous Cast for High End Audio Devices

Recently we were asked whether single crystal of OCC wire is affected by annealing process which is very important and unavoidable process, Our answer is NO. Here are some reasons.

Annealing is a crucial process in the treatment of single crystal copper materials. It is essential to understand that annealing does not have an impact on the quantity of single crystal copper crystals. When a single crystal copper undergoes annealing, the primary purpose is to relieve the thermal stress within the material. This process occurs without any alteration in the number of crystals. The crystal structure remains intact, neither increasing nor decreasing in quantity.
