DiFruscia Industries copper plates parts to MIL-C-14550 and AMS 2418, under DFI’s AS9100D quality system. Copper plating is not a Nadcap special process.

What copper plating does

Copper electroplating deposits a soft, highly conductive layer of copper. It is used as a functional finish on its own, and as an undercoat that improves the adhesion and coverage of later plating. See Copper Plating.

The specifications

Callout	What it covers
MIL-C-14550	Electrodeposited copper. Classes set the minimum thickness
AMS 2418	Copper plating for aerospace parts

What to expect

High electrical conductivity, and good solderability.
A base for plating over with other finishes.
Copper tarnishes. Plan a topcoat, a plate-over or a protective treatment if appearance matters.
Barrel plated. Small parts tumble in a rotating, perforated barrel in the plating bath, for an even, economical finish on high volumes of fasteners, pins, contacts and other small components.

How to call it out on the drawing

Give the class or the thickness your application needs.
High-strength steels may need hydrogen embrittlement relief baking after plating. Put the part’s hardness on the PO.
Barrel plating suits small, robust parts. For delicate, large or cosmetic-critical parts, ask DFI about a different approach.

Where it’s used

Electrical contacts, grounding hardware, aerospace hardware and small components.
