scope:

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

Material Description.

Platings to this specification are subdivided into three performance classes. Class A is intended for exterior components with severe service conditions likely to include damage from denting, scratching, and abrasive wear, such as those encountered by automotive bumpers. This class requires longer corrosion exposure resistance than Class B, for which components are expected to receive little additional mechanical abuse. For exterior applications, discontinuous chromium plate {(microporous (mp) or microcracked (mc)} in addition to a multiple layer nickel system shall be used. Class C is intended for interior applications and does not require the use of discontinuous chromium or multiple-layer nickel systems. For interior application a continuous chrome layer (r) is permissible. Plating per this specification is intended for use over metallic substrates; plating on plastics is specified in GMW 14668.

Typical Applications.

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.

Remarks.

Not applicable.
