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 Ti6Al4V 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 Ti6Al4V?
The composition of titanium alloy TC4 material is Ti-6Al-4V, which belongs to (α+β) type titanium alloy and has good comprehensive mechanical and mechanical properties. than the strength. The strength sb=1.012GPa of Ti6Al4V, the density g=4.51g/cm3, the specific strength sb/g=23.5, while the specific strength sb/g of alloy steel is less than 18. Titanium alloys have low thermal conductivity. The thermal conductivity of titanium alloy is 1/5 of iron and 1/10 of aluminum, and the thermal conductivity of Ti6Al4V is l=7.955W/m·K.
The main application of Ti6Al4V
Ti6Al4V is a titanium alloy material widely used in the aerospace and medical fields. After Tongrun Ti6Al4V powder is formed by selective laser melting (SLM) additive manufacturing equipment, the microstructure of the obtained parts is uniform and dense, and has the characteristics of rapid solidification.
TA15 is a high temperature titanium alloy with room temperature mechanical properties slightly higher than Ti6Al4V and medium high temperature mechanical properties. It is mainly used for the printing and forming of aerospace structural parts and engine parts. Tongrun independently developed TA15 powder. At present, the powder has been used in the forming of various types of titanium alloy parts. The maximum size of the parts has reached 1000mm. Some products have been successfully delivered to customers to meet the stringent requirements of the aerospace industry.
