Beryllium copper spring has good resilience, high thermal conductivity, good pressure resistance, good wear resistance, good plasticity and so on. Some properties can be improved by surface treatment.
For example: beryllium copper reed manufacturers want to increase the reed wear resistance, generally in the surface chromium plating. The chromium plating layer has high hardness and wear resistance, which can prolong the service life of the reed. According to the bath composition and process conditions, the hardness can vary in a wide range of 400 ~ 1200 HV. Chromium coating not only has high hardness and wear resistance, but also can play a role in decorative products.
