The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on 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.

3D Printing Alloy CoCrW Powder Health & Safety Information
Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.
The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.
Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.
"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.
Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.
Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.
Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the CoCrW Powder will be influenced by that.
