Buffalo Tungsten has been supplying tungsten powder for electrical contacts for over two decades. Electrical contacts are the metallic points that come together to complete a circuit. When they are in contact, electricity can flow through them. When they are not in contact, the flow of electricity is interrupted. Circuit breakers are a common household example of electrical contacts that most people are familiar with. There are also many commercial and industrial uses for electrical contacts. In other common products they are used on motors in appliances and  hey are used in relays and switches for control systems. They are typically made with a highly conductive metal such as silver or copper. They can be mixed with tungsten powder to improve their resistance to wear and oxidation. Tungsten carbide powder is also used in various types of contacts.
