Because of cheap electricity supply in bulk, it is possible that electrometallurgy is made into mass industrial production.

在铟、紫铜、锡、磷铜等机械接触中，铟电极具有最低的接触电阻，其他电极须经电冶成方能进行测定。
Among the pressure contacts studied, indium contact has the lowest contact resistance, while copper, tin, and phosphor-bronze contacts must be electrically formed before use.
The results show that this material has many advantages, such as dense microstructure, high strength, toughness and wearing resistance. The roll from this material has a low cost and long life time.
