Precision stampings - copper foil alloy
Expanded alloys, such as precision stampings of metal materials, are commonly used in the electronics industry, precision measuring tools, precision instruments, cryogenic engineering, optical instruments, aerospace and other fields. Expanded alloys are precision alloys that have the characteristics of anomalous thermal expansion or controlled thermal expansion.
Expanded alloys have small expansion coefficients; low strength and hardness; low thermal conductivity; high plasticity and toughness.
After the copper stamping parts are processed, the surface treatment can also be carried out, and the surface treatment process can be sandblasted, polished, and pickled. The expanded alloy has good electroplating properties, and the surface can be plated with gold, silver, nickel, chromium and other metals.
