Sherbrooke Metals is a primary manufacturer of copper & silver tungsten discs, bars, rings, rods with special shapes available.
We are a stocking distributor of tungsten & molybdenum rod & plate.
We also offering access to Copper-Tungsten Carbide material.
A group of welding processes where joining of metal is accomplished by the heat produced from the resistance of the article to the flow of electrical current in a circuit of which the article is a part. This occurs when pressure is directed at the electrodes where the electrical circuit is initiated and concluded.
ELECTRICAL CONTACT MATERIALS
Neither copper nor silver will alloy appreciably with Molybdenum or Tungsten, but through a tightly controlled powder metallurgy process, Sherbrooke produces a homogeneous bi-metal for electrical contact use. These bi-metals afford the user superior chemical, mechanical and electrical properties.
In addition, the high electrical and thermal conductivity of the silver or copper along with the arc-resistant and non-welding properties of Molybdenum or Tungsten, provide the customer with a wide range of bi-metals to best suit their needs.
Because these bi-metals withstand the effects of the arcing incident to the interruption of large current they are often used for circuit breakers, relays, switches and heavy duty contractors.
