Reputation depends on quality, quality comes from Hard!
Alumina Ceramic:
As energy prices continue to rise, the world's major aluminum companies began to turn their attention to the construction of aluminum production base to the low-cost Middle East and Africa. By reducing the electricity cost of the left and right production costs, and ensuring the price competitiveness of aluminum production, it has become the focus of the world's major aluminum companies. From the domestic policy analysis, the national industrial policy has positioned the aluminum industry to meet domestic demand, and there will be differences in policy between high-precision products and low-tech products. Therefore, upstream and downstream aluminum companies should focus on the domestic market to expand the application of aluminum in the domestic market; expand the application of aluminum, increase the added value of aluminum applications, and increase the technological content. In addition, aluminum producers should pay more attention to the development of related industries and downstream industries, especially the development trends of transportation, power, packaging, home appliances, etc., while increasing technical research and technology investment. According to the survey, domestic alumina imports remained at a high level year-on-year, mainly due to the fall in the price of imported alumina. According to statistics, as the main source of domestic alumina imports, Australia's alumina FOB average price fell by US$7/ton to US$312/ton in June, and after entering July, Australia's alumina FOB fell to US$305/ton. The price of CFR to Lianyungang also fell to US$328/ton.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
