Aluminium Oxide Grit 24 Mesh Manufacturers USA

The thermal conductivity indicates the speed of wholesale brown fused alumina heat transfer when the object is suddenly cold or hot. The thermal conductivity a of silicon carbide can be 6.28 ~ 9.63w.m1.k. that of corundum can be 1.5702.41w.m1.k. The hardness of brown corundum is a little lower than that of common abrasives. When grinding, it has good grinding performance and strong cutting force.

The temperature difference between the inner and outer layers of the products with large thermal conductivity is small, which correspondingly reduces the thermal stress between the inner and outer layers, and is conducive to improving the thermal shock stability. For the manufacturing of white aluminum oxide abrasive tools, the abrasive with high thermal conductivity is selected, which is conducive to heat dissipation during grinding. The melting point of a-Al2O3 is 2050 ℃. 

(aluminium oxide grit 24 mesh manufacturers usa)The melting point is the melting temperature of the crystal. The melting point of brown aluminium oxide is in the range of 1850~2050 ℃. The melting point of SiC is related to the atmosphere, which is in the range of 2200 ~ 2700 ℃. Corundum is suitable for processing steel, silicon carbide is suitable for processing non-ferrous metals and non-metallic materials. white fused aluminium oxide is one of the most common and widely used abrasives.

However, in the process of grinding, the 100 grit aluminum oxide white particles have good crushing resistance, that is to say, good toughness, which is suitable for grinding metals with high tensile strength, such as rough grinding and regrinding of ordinary steel, especially for carbon steel, general alloy steel, and also for grinding malleable cast iron and hard bronze. White corundum is another basic kind of common abrasive. Its hardness is slightly higher than that of brown aluminum oxide 250 grit.(aluminium oxide grit 24 mesh manufacturers usa)

brown fused alumina is suitable for grinding steel with high hardness, such as high carbon steel, high speed steel, quenched steel, etc. it is also suitable for machining workpieces that are prone to burn, such as grinding of cutters, thin-walled workpieces and precision grinding of alloy steel, etc. Single crystal corundum has good multi edge cutting edge, high hardness, high toughness value, strong grinding force, less grinding heat, long brown fused alumina suppliers cutting life.

(aluminium oxide grit 24 mesh manufacturers usa)Thermal conductivity is particularly important for brown fused alumina oxide refractories. It can process hard and tough steel, such as stainless steel, high vanadium high speed steel, etc. it is also especially suitable for the grinding processing and large feed grinding of easily deformed and easily burned workpieces. Its brittleness is moderate and its cutting performance is good. It is suitable for aluminium oxide grit suppliers surface machining or form grinding with high roughness requirements.

The crystal size of brown aluminum oxide is small, its strength is high, its self sharpening property is good, and it can be used for deep grinding. In the process of grinding, the microcrystalline corundum grains are in the state of micro fracture and have good self sharpening, so it is suitable for heavy load slow feed grinding with large grinding depth. brown fused alumina 60 grit is rose colored, so it is called rose colored corundum in foreign countries.(aluminium oxide grit 24 mesh manufacturers usa)
