Copper

Copper layers offer extremely high electrical and heat conducting properties, which are only surpassed by silver. Copper is therefore often used as a heat and electricity-conducting layer. Copper is infrequently used as a final layer as it offers limited resistance to tarnishing in the air.

As a base layer for nickel or chrome, copper provides additional improved corrosion protection and is used for decorative effects.

Advantages

  • High conductivity
  • High heat conductivity
  • Solderability
  • Low hardness and high ductility
  • Good polishing qualities

Properties

Post-treatment such as passivation or an additional thermal procedure, can change or strengthen the properties of a coating. Our experts are happy to offer you advice for your project – contact us to find the optimal surface treatment for your workpiece.
