Chemical properties
|
|
Chemical properties are stable, not easy to be oxidized and corroded. Generally, surface treatment is not required. Sometimes, surface plating is used to enhance the mechanical properties of products, such as zinc plating, nickel plating, tin plating, etc
|
|
Temperature characteristic
|
|
With good temperature stability, the maximum working temperature can reach 350℃
