3D Printing Alloy CoCrW Powder (Stellite Alloy) is one. Stellite alloy can resist wear, corrosion, and high-temperature oxygenation. CoCrW has a smooth, high-sphericity surface.
About CoCrW Powder for 3D Printing
3D Printing Alloy CoCrW Powder from Stellite is one of these alloys. These hard alloys are resistant to wear, corrosion, and high-temperature oxygenation. They are also known as cobalt based alloys. Initially, the Stellite alloy was a binary cobalt-chromium alloy. Later it evolved to a cobalt chromium-tungsten ternary mixture. Cobalt Cr-W Alloy is an alloy consisting of cobalt. This alloy contains a significant amount of chromium-tungsten as its main component. There are also small amounts of molybdenum (niobium), silicon and carbon. They are available in a variety of forms depending on the alloy composition, including as welding wire, powders for hard surfacing and spray welding.
The basic composition of cobalt-chromium-tungsten alloy is: Co:50%~58%,Cr:28%~30%,W:4%~6%,Ni:2%~4% and other alloy composition, melting point is 1470.As can be seen from the composition of the alloy, the cobalt and tungsten content of the alloy are very high, which makes the material has excellent high-temperature performance and has poor thermal conductivity. This is what makes the cobalt chromium and tungsten alloy used in grinding spark is dark red. Because of this, it is difficult to see the sparks from the surface of the workpiece.

How3D Printer Alloy CoCrW Pulveris produced?
Once the iron waste has reached its melting point the raw materials for cobalt chromium, nickel, tungsten and sulfur are added. After 40-60min of high-temperature treatment, temperature drops to 1150-1200°C. Temperatures then drop to 880-970°C, where it is possible to age the mixture for 2-3 hours. Next, the temperature goes back to 880-970°C. An annealing procedure is used to obtain the cobalt chromium or tungsten.
3D printing alloy CoCrW powder
CoCrW Powder is one of many rough alloys which can resist wear, corrosion, and oxidation at elevated temperatures. Based on their composition, the alloy can be made into wires or powders for hard substrates. They also have the ability to spray. These alloys can be used to make castings, forgings or powder metallurgy pieces.
COCRW can be used for laser/electron-beam additive manufacturing (SLM/EBM), in powder metalurgy (PM), spraying or welding, and many other applications. It is used primarily for the 3D printing biomedical products, including teeth and artificial joints.
Cobalt Cr-W is a widely-used alloy in engine engines, marine engines, and other aircraft.
The casting and non-vacuum smelting of early cobalt chromium -tungsten alloys was used. The vacuum smelting of boron or zirconium is used for later-developed alloys such as the MAR-509 alloy.
Generally, cobalt-chromium-tungsten alloy lacks a uniform strengthening phase. Its strength at low temperatures (between 50-75% and nickel-based alloy) is not as high, however, it does have excellent strength and thermal fatigue resistance. It can be used for making nozzle guidevanes and guides vanes of aircraft jet engines, industrial gas turbines and naval gas turbines.
Storage condition of CoCrW powder:
CoCrW’s powder performance will suffer from damp reunion. Additionally, CoCrW should not be exposed to stress.
Packing & Shipping of CoCrW powder:
You can choose from many packing options depending on your CoCrW Powder quantity.
CoCrW Powder Packaging:vacuum Packing, 100g to 500g, 1kg/bag or 25 kg/barrel. Or as you request.
CoCrW shipping: CoCrW can be shipped by sea, air or express as soon after payment receipt.
