Sn-Co-Zn Alloy Plating Chemicals Additives To Replace Chromium Plating RC-90
1. Properties
- The deposit appearance is similar to chromium deposit. The anti-corrosion and brightness can compare with chromium deposit, the covering ability is superior to standard chromium plating.
- The energy consumption is lower than that of chromium plating.
- Suitable for general barrel plating on small parts, production efficiency can increase.
- The technique is used for light industrial products without special toughness demands. It can get big economic benefit due to being as a substitute for chromium plating.
