Irregular Tungsten Carbide
1)High hardness&density
2)Good corrosion resistance
3)Good abrasive resistanceTungsten Cemented Carbide Grades, Properties And Applications Recommended

Cemented carbide is a kind of alloy material which made of refractory metal hard compounds and bording metal throught powder metallurgy technology. It possess high sstength, high hardness,wear resistance and corrosion resistance. It is known as”industrial teeth” and widely uesd in Military industry, aviation, machinery, metallurgy, oil drilling, mining tools, electronic communications, construction, etc
