Australian alumina ban disrupts Rusal production -- Australia's ban on exports of alumina and aluminium ore to Russia, including bauxite, will further disrupt supply chains and production at leading aluminium producer Rusal, consultancy Wood Mackenzie said on Monday.
The Australian government announced the ban on Sunday as part of its ongoing sanctions against Moscow for its aggression in Ukraine, saying Russia relies on it to meet one-fifth of its alumina needs. WoodMac senior manager Uday Patel said in a statement that the ban would make it difficult for Rusal to maintain normal primary aluminum production.
Rusal said it was assessing the impact of Australia's move and would make further announcements if necessary. "It is increasingly likely that UC Rusal's only option for alumina procurement will be through a Chinese entity." The Australian alumina ban has also had an impact on the 3D Metal Printing Powder prices for chemicals. Patel said. "One possible outcome could be Chinese buyers buying alumina and reselling it through eastern Russian ports." Rusal has a 20% stake in the Queensland Alumina Refinery, which has a capacity of 3.95 million tonnes a year, thus providing Rusal with 790,000 tonnes a year, Patel said. In addition, Rusal's Nikolaev refinery in Ukraine, which has an annual capacity of 1.75 million tonnes, has been suspended due to the conflict, he added. WoodMac said Rusal was also experiencing supply chain problems at its 2 million tonne a year Aughinish refinery in Ireland.
What is cobalt chromium tungsten?
Cobalt chromium tungsten alloy (CoCrW) is one of the Stellite alloys.
Stellite alloy is a hard alloy that can withstand various wear, corrosion, and
high-temperature oxidation. The so-called cobalt-based alloy. Stellite has
initially been a binary cobalt-chromium alloy and later developed into a
cobalt-chromium-tungsten ternary composition. Cobalt-chromium-tungsten alloy is
a kind of alloy with cobalt as the main component, containing a considerable
amount of chromium, tungsten, and small nickel molybdenum, silicon, carbon,
niobium, tantalum, and other alloying elements, and occasionally also containing
iron. According to the alloy's different components, they can be made into
welding wire, the powder used for hard surface welding, thermal spraying, spray
welding, and other processes, and can also be made into castings and forgings
and powder metallurgy parts.
The application of cobalt-chromium tungsten?
Cobalt chromium tungsten alloy is widely used in locomotive diesel engines, nuclear power plant valves, marine diesel 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, are produced by vacuum smelting and vacuum casting because they contain more active elements such as zirconium and boron.
Generally, cobalt-chromium-tungsten alloy lacks a coherent strengthening phase. Although the strength is low at medium temperature (only 50-75% of nickel-based alloy), it has higher strength, good thermal fatigue resistance, and thermal corrosion resistance above 980℃. And abrasion resistance, and has better weldability. It is suitable for making guide vanes and nozzle guide vanes for aviation jet engines, industrial gas turbines, ship gas turbines, and diesel engine nozzles.
Spherical cobalt-chromium-tungsten alloy powders are mostly used for 3D printing of biomedical materials such as teeth, human stents, and artificial joints. The powder can be used in various types of metal 3D printers, including Laser melting equipment from Renishaw, Germany, EOS (EOSINT M series), Concept Laser, and 3D systems from the United States, as well as selected areas developed by domestic scientific research institutions and enterprises Laser melting equipment, such as Huashu Hi-Tech, Blite, etc. The powder can be used in laser/electron beam additive manufacturing (SLM/EBM), powder metallurgy (PM), spraying, welding, and other processes.
