A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including CoCrW Powder .
About 3D Printing Alloy CoCrW Powder:
3D Printing Alloy CoCrW Powder is one of the Stellite alloys, which are hard alloys resistant to various types of wear and corrosion as well as high-temperature oxidation. Namely commonly referred to as cobalt-based alloy. Initially, the Stellite alloy is a cobalt-chromium binary alloy and later developed into a cobalt-chromium tungsten ternary composition. Cobalt-Cr-W alloy is an alloy with cobalt as the main component, containing a considerable amount of chromium and tungsten and a small amount of nickel, molybdenum, silicon, carbon, niobium, tantalum and occasionally iron. Depending on the composition of the alloy, they can be made into welding wire, powder for hard surfacing, thermal spraying, spray welding and other processes, as well as cast and forged parts and powder metallurgy parts.
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. It is these characteristics that make the cobalt-chromium tungsten alloy in the grinding process spark is dark red, the number of sparks is very small, the metal from the workpiece surface is easy to block the grinding wheel, so that the grinding conditions quickly deteriorate, at the same time produce a lot of grinding heat can not quickly spread, resulting in low efficiency, workpiece surface burns.

How is 3D Printing Alloy CoCrW Powder produced?
The waste iron is smelted to the melting point, and then the eight raw materials of cobalt, chromium, tungsten, sulfur, silicon, carbon, aluminum and copper are added in turn, and then the temperature is reduced to 1150-1200°C for high-temperature solution treatment for 40-60min, and then the temperature is again reduced to 880-970°C for aging treatment for 2-3h, and the cobalt, chromium and tungsten alloy is obtained through annealing treatment again.
Applications of 3D Printing Alloy CoCrW Powder:
CoCrW powder is one of the rough alloys that can resist various types of wear, corrosion and oxidation at high temperatures. Depending on the composition of the alloy, they can be made into welding wires, powders for hard surface substrates, thermal spray, and spray. They can also be made into castings, forgings and powder metallurgy parts.
COCRW powder can be used in laser/electron beam additive manufacturing (SLM/EBM), powder metallurgy (PM), spraying, welding and other processes. The powder is mainly used for 3D printing of biomedical materials, such as teeth, body supports, artificial joints, etc.
Cobalt-Cr-W alloy is widely used in locomotive engines, nuclear power plant valves, Marine engines and various aircraft.
Early cobalt-chromium - tungsten alloys were produced by non - vacuum smelting and casting processes. Later developed alloys, such as MAR-M509 alloy, which contains more active elements such as zirconium and boron, are produced by vacuum smelting and vacuum casting.
Generally, cobalt-chromium-tungsten alloy lacks a uniform strengthening phase. Although its strength is low at medium temperature (only 50-75% of that of nickel-based alloy), it has high strength, good thermal fatigue resistance, thermal corrosion resistance and abrasion resistance at temperatures higher than 980℃, and good weldability. It is suitable for the production of guide vane and nozzle guide vane of aviation jet engine, industrial gas turbine, naval gas turbine and nozzle, etc.
Storage Condition of CoCrW Powder:
The damp reunion will affect CoCrW powder dispersion performance and using effects, therefore, CoCrW powder should be sealed in vacuum packing and stored in cool and dry room, the CoCrW powder can not be exposure to air. In addition, the CoCrW powder should be avoided under stress.
Packing & Shipping of CoCrW Powder:
We have many different kinds of packing which depend on the CoCrW powder quantity.
CoCrW powder packing:vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
