Copper in color and matte to a very shiny finish.
Good corrosion resistance when used as undercoat.
A number of copper processes are available, each designed for a specific purpose: Brightness (to eliminate the need for buffing), High speed (for electroforming) and Fine grain (to prevent case hardening), etc.
Stress relief steel parts cold straightened or suspected of having residual tensile stresses (350º +/- 25º F – 3 hours).
Parts with tensile strength over 210 Ksi bake 24 hours within 4 hours after plating.
