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.
