Your Metal Finishing Solution

Silver Plating

Silver is a cost effective solution for applications that require low contact resistance, high thermal conductivity and chemical stability. AST offers matte, semi bright and bright silver platings ranging from 99.0% to 99.9% purity that conform to QQ-S-365 and ASTM B700 specifications. A RoHS compliant post plating chromate treatment is also available. Silver is commonly used for brazing, soldering, electrical contacts, electronics and medical applications.
