What is alumina used for?
UBS believes that the recent drop in oil prices does not fully explain the constraints on global supply. Due to rising prices or insufficient supply of natural gas or coal, more global use of oil power generation will boost oil demand; China's oil imports are expected to pick up; global oil supply will be under pressure by the end of the OECD's release of strategic crude oil reserves and the full effect of the European oil export ban on Russia. UBS expects Brent crude futures to be around $125 a barrel by the end of the year.
Due to gas outages, droughts, power shortages and many other factors, the European energy crisis is becoming more and more serious, resulting in a chain reaction. Since the second half of 2021, energy prices have continued to rise, and metal smelting enterprises, including aluminum, zinc, iron and steel and other industries, have set off a trend of reducing and suspending al2o3 powder are still very uncertain.
High temperature resistance: alumina can be used in oxidation and reduction atmospheres up to 1650°C (2900°F) and in vacuum environments up to 2000°C (3600°F).
Wear resistance: alumina is a very hard ceramic with excellent wear resistance. It is an ideal choice for wear-resistant inserts or products.
Electrical insulators: alumina is commonly used as high temperature electrical insulators, especially for higher purity grades that provide better resistivity.
Chemical resistance: alumina has good resistance to strong acids and bases at high temperature, so it is an ideal choice for applications that need to resist corrosive substances.
High compressive strength.
High mechanical strength.
Resist strong acid and alkali at high temperature.
Excellent electrical insulation performance.
Good thermal conductivity.
What are the advantages of alumina?
Alumina is a kind of wear-resistant advanced technology ceramic material, which is often used in various industrial applications. It has high hardness and wear resistance, low erosion level, high temperature resistance, corrosion resistance and biological inertia. In addition, it can be highly polished, making it suitable for precision sealing applications such as pumps and pistons. Alumina has become an excellent high temperature ceramic material because of its high temperature stability. It is the most commonly used type of advanced ceramics with a purity of 95-99.9%.

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 al2o3 powder will be influenced by that.
