Iridite NCP

Iridite NCP is a hexavalent chromium free conversion coating that is mainly used as a pre paint coating for aluminium or as a corrosion resistant finish that still allows parts to be electrically conductive. It is able to offer over 1000 hours of protection in salt spray tests and can operate at high temperatures up to 350 degrees celsius.

Iridite NCP is a colourless finish that leaves parts with a silver appearance

We typically apply this finish to spec MIL-DTL-5541 Type 1 Class 1A or Class 3

Iridite NCP is ROHS compliant
