Copper Plating Services – Copper Deposit Properties
Copper plating offers improved electrical properties, improved corrosion resistance, acts as a barrier between the substrate and over-plate and works to improve adhesion of over-plate when nickel cannot be applied. Copper plating also increases the success of brazing and is applied in many high-temperature applications.
Similar to nickel, copper also functions as a sacrificial lubricious coating when premature tool failure is a concern. Abrasive substrates such as beryllium copper and stainless steel are coated with copper to increase the life of wire forming equipment.
After plating with copper, antioxidants and oils may be applied to prevent the oxidation of the copper when exposed to air.
