Tungsten-Carbide Rod
Description
Tungsten-Carbide alloy is a composite material comprised of individual tungsten carbide grains imbedded in a ductile metal binder matrix of either cobalt or nickel. It is renowned in industry for its superior durability and high melting point. The resulting alloy is 2-3 times as rigid as steel and has a compressive strength surpassing all known melted, cast, and forged metals. It is highly resistant to deformation and keeps its stability at both extreme cold and hot temperatures.
Alfa Chemistry specializes in providing high quality tungsten-carbide rods on the market today. We can develop grades as per your requirement and make the same shape as your drawing. Laser marking and neutral package are also available for your benefits.
