scope:

This specification covers basic requirements for copper-nickel-chromium electroplated metallic parts, including assemblies.

Material Description. Plating to this specification is subdivided into three performance classes:

  • Class A: Exterior components with severe service conditions, likely to include damage from denting, scratching, and abrasive wear, such as those encountered by automotive bumpers and assist steps.
  • Class B: Exterior components without stone-chipping exposure or other mechanical abuse, such as door handles or emblems (not on the front of the vehicle).
  • Class C: Interior components.

For exterior applications, discontinuous chromium plate (microporous (mp) or microcracked (mc)) in addition to a multiple layer nickel system shall be used.

For interior applications, a continuous chrome layer (r) is permissible. The use of discontinuous chromium or multiple-layer nickel systems is not required for interior components.

Plating per this specification is intended for use over metallic substrates; plating on plastics is specified in GMW14668. For plating of stainless substrates, see GMW15613.

Symbols. Not applicable.

Applicability. This type of finish shall be principally used for decorative purpose, including bright and other (e.g., satin, brushed, grained) appearances for interior and exterior applications, as defined by styling and specific appearance standards.
