Silver (Ag) is a precious metal that has many useful properties. It is strong, ductile, easy to work with, highly reflective, and has good corrosion resistance. However, the biggest drawback of silver is its tendency to tarnish. Silver tarnishes when exposed to the air, mainly through hydrogen sulfide. Silver tarnish is easily removed by rubbing the silver with lemon juice or vinegar.

Alloys of silver are used in a wide range of applications and industries due to their low cost, good electrical conductivity, high machinability, and good reliability characteristics. The tin-silver-copper alloy family is also a popular alternative to lead solder for electronics assembly. It is also widely used in medical equipment like MRI scanners and in structural components for aerospace and automotive industries.

The addition of small amounts of other elements to silver provides additional useful properties. For example, adding copper (Cu) to aluminum increases strength while reducing the risk of corrosion. It also improves solderability. Other common alloying elements in aluminum are magnesium (Mg) and silicon. The 5000 series of aluminum alloys contains these and is commonly found in vehicles, pressurized vessels, bridges, and other structural components.

American Elements produces a variety of high purity aluminum-silver master alloys with various standard ratios of Al:Ag and custom alloy compositions. We provide these in a range of shapes, including discs and ingots. We can also perform advanced chemical analysis on all our alloy products using X-ray fluorescence, glow discharge mass spectrometry, and inert gas fusion.
