Description:

Alloy CoCrW powder is a Stellite alloy, which is a cemented carbide, which can resist various types of wear, corrosion and high temperature oxidation. It is commonly referred to as a cobalt-based alloy. At first, Stellite was a cobalt-chromium binary alloy, and later developed into a cobalt-chromium-tungsten ternary alloy. Cobalt-chromium-tungsten alloy is an alloy with cobalt as the main component, containing considerable amounts of chromium and tungsten, as well as a small amount of nickel, molybdenum, silicon, carbon, niobium, tantalum, and occasionally iron. According to the different alloy composition, it can be made into welding wire, powder for hard surfacing, thermal spraying, spray welding and other processes, and it can also be made into castings and forgings and powder metallurgy parts.

 

Application field：

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.

Applicable Equipment: Powder can be used in various types of metal 3D printers, including Renishaw from the UK, EOS (EOSINT M series) from Germany, Concept Laser, 3D systems from the United States and many other laser melting equipment.
