18th,June.2019  The life of tungsten carbide starts from power – WC power and cobalt or nickel power (most often). The whole tungsten carbide manufacture process as the bellowing picture shows, you can just image the whole process as “rice cooking”, of course , if you don’t know how to cook rice , it’s doesn’t matter, follow us step by step with detailed work flow breakdown : 1 Power Mixing For example , if we need the material of grade K20 , then the listed composition (6.25% Cobalt , 4.25% Tantalum carbide,89.5%tungsten carbide power,4.25% Niobium Carbide ) mixing together with forming agent ( PEG, Paraffin, rubber) in balling machine.2MillingUsually 48hrs , differ from required power size 3 Spray & DryingThe prepared power with good fluidity by this way compared with traditional baking method， the grain shape of tungsten carbide is round pellets which can be well fulfilled in every mould corners. 4 Pressing & Shaping  The prepared mixing power been transit into mould， if the mould designed shape same as desired ones, then no need shaping. If the shape not as desired ones, then we go ahead with shaping by turning or milling 5 Vacuum/HIP sinteringPlace the pressed or [...]

4th,June.2019        Tungsten carbide, it’s been often called as “cemented carbide”, “hard alloy” “widia” “carbide” or “hard metal”. It is a mixture which is generally consisting of 75%-97% tungsten carbide (wc) and 3%-25% cobalt (Co). Physical properties vary depending upon the specific mixture. But when tungsten carbide mentioned as raw material or composition, it is a grey powder(wc). Wikipedia defines tungsten carbide /cemented carbide as below:“It is a hard material used extensively as cutting tool material, as well as other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. It commonly use tungsten carbide(WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. “We believe most people are familiar with the application of cutting tools( carbide milling and turning inserts , end mills, rotary burrs )  We hope that you can get one more material option for your current wear parts that maybe originally made of high speed steel, stainless still, ceramics, etc. by our introduction of tungsten carbide.Physical propertiesTungsten carbide has been made to cutting tools and wear parts due to its advantages [...]
