Product Description

Tin Cobalt Process

Tin-cobalt alloy plating process is an ideal replacement for chrome plating as it provides excellent 'chrome like' finish on bright nickel plated components. Chromium plate on small barrel plated components till date is not commercially viable. Fully bright lustrous, decorative 'chrome like' finishes on bright nickel plated smaller components through barrel plating operation is the most unique advantage of this process. Growel introduces this innovative technology offering chromeless chrome bright finish ~ a major step forward to replace the usage of carcinogenic hexavalent chrome.
