Detailed Product Description

                          Tungsten Carbide -Detailed introduction

Hard alloy ,with high hardnessgood wear resistancehigh elastic modulus and compressive strengthsmall thermal expansion coefficient and good chemical stability,is very important in morden toolwear resistanttemperature resistant and corrosion resistant materials.Hard alloy is componented by rigid matrix and bonded metal.In which,rigid matrix is one kind of Metal Nitrides and difficult to melt.The chief composition is Tungsten Carbide,and secondly following is Titanium CarbideTantalum CarbideNiobium Carbide and Vanadium Carbide.Tungsten Carbon,as the basic stuff of cemented alloy,is a kind of gray powder with metal luster.Its hardness is same as Diamond with its proportion of 15.6,melting point of 2780 degree Centigrade,boiling point of 6000 degree Centigrade .With high purityminor grain sizeuniformly distributed granularityfull range oftypes,our hard alloy has superior property in hardnesstoughnesswear resistance and flexural strength.
