Black Alumina Wholesale Suppliers UAE

As black aluminium oxide grinding applications, abrasives should have the following basic properties: Abrasives should have a relatively high hardness, and the magic hardness should be higher than the hardness of the workpiece being processed, and they must have good abrasion resistance. In general, under the same conditions, the higher the hardness of the white fused alumina suppliers abrasive, the better its abrasion resistance and cutting performance.

Abrasives should be processable and pelletizable, capable of being made into particles of a wide range of brown fused alumina sizes, uniform shapes, and regular sizes. For grinding, in order to obtain the required processing accuracy and efficiency, the abrasive must be granulated into uniform and uniform particles with a certain size. Therefore, pink corundum materials which are difficult to be processed into a granular shape are not suitable as abrasives.


For example, hard alloy, although its hardness is very high, but its toughness is also quite high, it is difficult to process and granulate, so it is not suitable for white fused alumina price. The abrasive should have some toughness. The toughness of honing abrasive refers to the ability to resist chipping and maintain the cutting edge during the grinding process. The silicon carbide abrasive should be able to withstand high temperatures and have high temperature stability.


During grinding, a large amount of heat is generated in the contact area between the brown aluminum oxide and the workpiece, especially high-speed grinding and heavy-duty grinding. The local temperature can be as high as 1500 ° C. Therefore, the abrasive used should be able to maintain its inherent hardness and strength at high grinding temperatures. Therefore, the glass beads manufacturers abrasive should be chemically stable to avoid chemical abrasion. 


For example, boron carbide, although its hardness is higher than that of brown fused aluminium oxide, is easily oxidized at high temperatures, so it is not suitable for use as an abrasive tool, and can only be used as an abrasive paste. Abrasives should be chemically stable and should not react chemically with workpieces, bonding agents, or coolant during the green silicon carbide grinding process. Grinding is not just a purely mechanical process.


With the development of metallurgy, brown aluminium oxide chemical industry, building materials, electrical, transportation and some emerging industries, the requirements for material properties continue to increase. Silicon carbide-reinforced metal materials have excellent thermal creep resistance and thermal shock resistance, and garnet abrasive price have become an indispensable material for the outer shell of aerospace vehicles and rocket engines.


In addition to grinding applications, more artificial ordinary abrasives are used for non-grinding purposes. Today, the amount of brown fused alumina price used in refractories, steelmaking deoxidants, and carbon-silicon rods has exceeded the amount of grinding. Chemical reactions also play a very important role. Abrasives are used for a wide range of black silicon carbide purposes. Its grinding application is greatly limited. 


The fine white alumina powder is not coarser than the ordinary abrasive grains with a particle size of 240 or the superhard abrasive grains finer than 36/54 μm. Refractory materials and engineering ceramic materials made of corundum and silicon carbide show good oxidation resistance, impact resistance, and glass bead abrasive thermal conductivity, and will be key parts of steam turbines, engines and heat exchangers in the 21st century.
