Enthone’s Cuprostar NC alkaline is a cyanide-free bright copper process designed to be a cost-effective and environmentally sound alternative to traditional cyanide-containing processes. It is engineered for use on virtually all commonly used base materials, and specifically is said to provide high yields and reduced rejects when plated on aluminum, brass, steel and zinc die cast parts.

Cuprostar NC features improved throwing power on complex part geometries, resulting in complete, consistent and uniform coverage, the company says. The process does not require a specialized pretreatment cycle and uses virtually the same process sequence as a cyanide-based system. By adjusting the temperature, pH and copper content, the Cuprostar NC process can be modified to meet specific brightness, current density, adhesion and throwing power application requirements.
