Description
Precision structural components, positioning parts, optical and metrology equipment components.
Invar primarily employs low-temperature processes such as nickel plating, electroless nickel plating, blackening and sandblasting.
Higher cost, limited mechanical strength, and its excellent low-expansion properties are only effective within the temperature range of -100°C to +200°C. Overheating can cause deformation.
