Silver Bullion - Industrial Uses of
Silver
The industrial uses of silver, physical silver that is, are listed
here:
- Batteries
Many batteries - rechargeable and disposable - are manufactured with silver alloys as the cathode or negative side. Although expensive, silver cells have power-to-weight characteristics superior to their competitors. The most common of these batteries is the small button-shaped silver-oxide cell - used in cameras, toys, hearing aids, watches and calculators - which is approximately 35 percent silver by weight.
- Bearings
Steel ball bearings electroplated with silver have greater fatigue strength and load carrying capacity than any other type. These bearings are used in continuous, heavy-duty applications such as in jet engines.
- Brazing and Soldering
Silver facilitates the joining of materials - called brazing when done at temperatures above 600 degrees Celsius and soldering when below - and produces naturally smooth, leak-tight and corrosion-resistant joints.
- Catalysts
A catalyst is a substance that allows or facilitates a chemical process. For example, heat is the world’s most common catalyst and helps many processes to take place -- such as cooking food or baking pastries. Silver, because of its unique chemical properties, has become an increasingly important catalyst for many industrial processes.
- Electronics
Because of silver’s excellent electrical conductivity, it finds many applications in electronics from printed circuit boards to switches and TV screens.
