Colmonoy® Origins – A Nickel-based Hardfacing Alloy

Описание: The first nickel-based hardfacing alloy, Colmonoy® was developed by two metallurgists Mr. Norman Cole and Mr. Walter Edmonds in 1937.

Colmonoy® was first utilized extensively to extend the useful service life of downhole tools and drill bits for the oil industry.

During World War II, Colmonoy® was used to extend the lifespan of U.S. Army tank parts, such as drive gears and track sprockets.

Since its beginnings, the nickel-based hardfacing alloy has evolved. Other elements have been added to turn Colmonoy® into a whole range of rods and atomized powders, bringing new benefits in wear and corrosion resistant properties.

Regardless of form, whether rod or powder, Colmonoy® alloys have another important feature. As well as being primarily nickel-based, Colmonoy® also contain silicon and boron. The nickel, silicon and boron trio create a self-fluxing alloy that fuses not only to itself, but a wide range of metallic base materials including carbon steel, tool steel, dye steel, stainless steel, and cobalt alloys.
