About Tungsten Carbide WC Powder:
Tungsten carbide is made of both tungsten or carbon. Tungsten carbide formula What is the WC? Tungsten carbide molecular Weight It is 195.85
Tungsten carbide color: Although the most basic form is a grayish powder, it can still be used in cutting and industrial machinery.

Young's modulus, which measures 530-700 GPa (between 77,000 and 102,000 ksi), is approximately twice as stiff as steel. It is also twice the denseness of steel. It is hard comparable to that found in corundum (aAl2O3). For polishing or finishing, only diamond powder and cubic boron nuitride can be used.
Tungsten caride can be also used in the production of tungsten carbide rings , tungsten carbide mens rings , tungsten carbide wedding bands , tungsten carbide mens wedding bands, etc. Because tungsten carbide rings price The cost of tungsten carbide rings is lower than those made from gold and platinum. It also has a greater scratch resistance than any metal. There are many styles and colors available, as well as inlays and inlays. black tungsten carbide rings , tungsten carbide rings gold .

Black tungsten carbide This hexagonal crystal has metallic luster, hardness and a similar appearance to diamonds. Tungsten carbide is an excellent conductor of heat and electricity. Tungsten carbide can't be dissolve in water or hydrochloric and sulfuric acids. However, it is easily soluble and can be broken down in hydrofluoric and nitric acids. Tungsten carbide in its pure form is very fragile. However, if there are small amounts of cobalt, titanium and other metals, it can be made less brittle. Tungsten carbide can be used to cut steel. To increase its anti-knock capability, it is sometimes combined with titanium carbide (or tantalum) or their mix. Tungsten carbide has a chemical stability. Tungsten powder is used for cemented carbide production.

It is simple. Tungsten Carbide WC Powder produced?
Utilizing metal tungsten or carbon as raw material, tungsten powder of an average particle size between 3 and 5 mm is mixed dry with a ballmill, then press-molded and put into a graphite resist furnace. Or, you can heat it to 14001700 using an induction furnace. Preferably 15501650. W2C is produced in the hydrogen stream and reacts at high temperatures to create WC. Or, first, the tungsten Hexacarbonyl can be thermally broken down at between 650 to 1000 degC in CO, and then reacts with carbon monoxide to create WC. W2C is possible at higher temperatures than these.
The chemical reaction formula
2W+C = W2C
W + C = WC
Hydrogenated tungsten trioxide (WO3) is then reduced to make tungsten dust. The average particle size for tungsten is 35mm. Next, press-form the mixture of tungsten and carbon black under pressure of approximately 1 t/cm2. You will need to heat the block of pressurized material in a graphite oven or crucible. Then, you can use pure hydrogen at a temperature of 14001700. Since W2C can be generated from the beginning of the process, the reaction begins around the tungsten particle. Because the reaction temperature is very low, the unreacted and intermediate W2C will remain. The reaction must then be heated to the high temperatures mentioned above. The raw tungsten particle size should determine the temperature. A reaction can be initiated at temperatures between 1550-1650degC for large particles that have an average size of 150 mm.
The chemical reaction formula
WO3 + 3H2 + W + 3H2O
2WO3 + 3C - 2W + 3CO2
2W+C = W2C
W + C = WC

Applicaciones Tungsten Carbide WC Powder:
Tungsten caride is used extensively in the manufacture of high-speed cutting tools and furnace structural materials. This is used in the manufacture of cutting tools, wear resistant parts, meltingcrucibles for metallics such as cobalt, copper and bismuth and wear-resistant semiconductor film.
Tungsten carbide is used for super-hard material as well as wear-resistant materials.
Tungsten carbide can be combined with other types of carbides to create a strong solution. WC-TiC-Co has been used extensively to create cemented carbide tools.
Tungsten carbide can also be used to modify NbC–C and TaC–C ternary-system carbides. It can decrease the sintering temperature while maintaining excellent performance. It is also used in aerospace.
Tungsten carbide powder (WC) can also be made by using graphite, tungsten hydride (WO3), and an reducing atmosphere at high temperatures of 1400-1600. You can make dense ceramic products by either hot pressing or hot isostatically pressing sintering.
Tungsten caride (WC), powder, can also be used in the production of high capability superfine or nano-crystalline horniness alloys.

Tungsten carbide powder storage conditions:
Tungsten carbide powder dispersion and uses effects should be considered. Niobium carbide NbC Powder must be stored in vacuum bags and kept dry in a cool place. NbC powder shouldn't be exposed to stress.

Packing and Shipping Tungsten carbide WC granules :
There are many options for packing, which vary depending on the amount of niobium-carbid NbC powder.
Tungsten carbide WC powder packing: You can vacuum pack 1kg per bag, 25kg/barrel or according to your requirements.
Tungsten carbide WC powder shipping: After receipt of payment, items may be sent out either by sea or by air.
