In May 2022, the demand for white aluminum oxide is lower because of the covid policy. Many abrasive tools and ceramic manufacturers don’t buy as many raw materials as normal. As a result, the white aluminum oxide price did not get much support.
In the past month, there are 7 white-fused alumina manufacturers in China cut production capacity. That number is same as last month. Among the 7 factories, five are Henan WFA factories and two are Shandong factories. Henan WFA manufacturers quitting is caused by Covid lockdown in Zhengzhou city.
In thermal spraying processing, ceramic powders such as Al oxide and tungsten carbide are usually used as coating materials. The powder is sprayed on the surface of the workpiece through high-temperature melting spraying. The formed coating has the effects of wear resistance, high-temperature resistance, and corrosion resistance.
Due to its high refractory temperature and high specific gravity, white fused alumina WFA aggregate is a kind of refractory commonly used in the refractory kiln and steel-making industry. The water absorption of WFA aggregate reflects the technical indexes of porosity. The porosity of WFA is generally less than 15% and the water absorption is less than 5%.
The bulk density of white aluminum oxide is a key index for abrasive production. Bulk density refers to the mass (weight) of abrasive in unit volume under the condition of natural accumulation. It is called LPD means loose pack density.
It is very important to use proper blasting media on surfaces of acrylic, plastic, aluminum, etc. It is proved by using white alundum grit will avoid black defects. White alundum grit won’t pollute workpieces.
White alox powder for lost wax precise casting is a refractory powder with proper particle range. Its main chemical is Al2O3. And it’s a kind of electrocorundum powder. In the production of precision casting, refractories have a great influence on the casting accuracy. Especially for surface materials, it is not only necessary to have high fire resistance temperature, but also need to have good fluidity, high density and appropriate particle size distribution.
The Australian government announced on March 20 that it would immediately stop exporting alumina and bauxite products to Russia. So, this move will bring more pressure on Rusal and further push up the international market price of aluminum raw materials.
White Aluminum Oxide Sandblasting Media also known as alumina sand, is a high hardness abrasive with a purity of 99%. Aluminum oxide blasting media is suitable for stainless steel, aluminum alloy, glass, steel castings, gel coat surfaces, and alloy parts. White aluminum oxide has high hardness, aggressive grinding performance.
White corundum powder can improve the thermal conductivity, wear-resistance, and dielectric properties of epoxy resin insulation composites such as insulating boards.
