Electroplating Processes for Various Metals – EPi

In 1954, EPi created the EBrite 2311, a singleadditive cyanide copper process, and in 1961, it continued pioneering the singleadditive nickelplating process with the EBrite 717. The company was the first to develop a productionproven, noncyanide, nonpyrophosphate alkaline copper electroplating process, the EBrite 30/30.
