Electrical Coatings
Impact Coatings provides a line of PVD coatings with unique properties for connectors and other electrical components. The coatings in many applications replace or outperform gold plating as a contact material. PVD coatings are particularly well suited with substrates that are difficult to electroplate, such as stainless steel, titanium, and even plastic.
Ultra MAXPHASE™ is a coating for extreme wear, corrosion and heat conditions, where electroplated gold is not sufficient.
Silver MAXPHASE™ is a cost-effective silver alloy with excellent tarnishing resistance, for maintained low contact resistance and solderability after environmental exposure.
Ceramic MAXPHASE™ provides superior power output and durability for metal bipolar plates for fuel cells.
