About Tantung
Tantung is a cast alloy cutting tool material composed principally of chromium ,tungsten ,columbium and carbon in a cobalt matrix . These elements combined in the proper proportions and cast in chill molds give tantung its most important characteristic , the ability to retain its cutting hardness t red heat temperature up to 1500℉, It is neither high speed steel nor carbide , it is unique .
Tantung has a high transverse rupture strength, low coefficient of fiction and excellent resistance to corrosion it is rough , readily adsorbs shock and impact ad is non-magnetic , it likes to work .
