Cadmium closely resembles to Zinc plating for some applications. Typical chromates applied include clear, yellow, olive drab and black. Cadmium is extremely toxic and should not be used on any part intended for use where direct food contact may occur. Typical thickness is .0002" - .0008" deposit. Cadmium use in harsh environments and aerospace application has no equal and Cadmium is second to none in aquatic or brackish application.
QQ-P-416F is the Federal standard for Cadmium Plating.
