Semi-bright Silver

Gleco offers QQ-S-365, ASTM B700, AMS 2410, AMS 2411 & AMS 2412 semi-bright silver plating for customers whose parts and components require electrical and thermal conductivity and strong corrosion resistance. This process delivers a semi-brilliant, white- metallic luster that is harder than gold but still ductile and malleable.
Purities for semi-bright silver plating are generally around 99.5%. Although silver plating is primarily used for industrial applications, such as electrical connectors, it can also perform well in appliance, telecom, automotive, and jewelry applications.
Semi-bright Silver Plating
Silver plating can be used to finish a wide range of materials, including:
- Copper
- Steel
- Titanium
- Graphite
- Ceramic
- Plastic
- Aluminum
The thickness of the silver coating itself can range from 1 micron for solderability and shorter shelf life to 10 microns for die attachment and thermo-compression bonding to 40 microns for applications requiring severe-wear resistance.
Several factors must be considered when formulating the plating bath, including the hardness, conductivity, and solderability requirements of the part or components being plated and the methods for testing adhesion. Typical silver-plating specifications include ASTM B 700, QQ-S-365, AMS 2410 and AMS 2412.
Because silver plating can tarnish when exposed to ozone, hydrogen sulfide, or air containing sulfur, a chromate post-treatment may be added.
