Black Synthetic Corundum Wholesale Supplier

First of all, introduce what is black corundum, also known as low alumina corundum(black synthetic corundum wholesale supplier). It is a kind of gray black crystal with α - Al2O3 and iron ore phase, which is made by smelting bauxite in electric arc furnace. It is characterized by low Al2O3 content and a certain amount of Fe2O3 (about 10%), so it has the characteristics of moderate hard bottom, high toughness, brown fused alumina price high temperature resistance and constant hot performance temperature.

Black corundum is mostly used for free grinding, such as the rough grinding of the grinder before electroplating, mainly used for polishing and white alumina sandblasting of stainless steel, metal products, optical glass, bamboo and wood products, and it is also a new abrasive for manufacturing resin steel grid grinding wheel, cutting pieces and gauze. From the introduction of "low aluminum" and "Fe2O3 (about 10%), we can see why the price of black corundum is low(black synthetic corundum wholesale supplier).


(black synthetic corundum wholesale supplier)Because aluminum is certainly more expensive than iron, brown fused alumina is mixed with more iron. The highest aluminum content of the first grade black corundum is 85%, that of the second grade is only 75%, and that of the third grade is 65%. The aluminum content just corresponds to the second grade, the second grade and the third grade sand of the pink corundum, and the price is in turn corresponding.


With the increase of vanadium content, the corrosion wear decreases(black synthetic corundum wholesale supplier). Rail, roll, etc. this form of wear is also known as contact fatigue wear(white aluminum oxide 240 mesh). Special attention is paid to the analysis and calculation of contact stress and the analysis of material structure and properties. The results show that the process of rolling fatigue wear has two stages, namely, crack initiation stage and crack propagation to spalling stage. After steel cupping treatment, the surface is mainly work hardening hardness.


The most common artificial abrasives are white corundum and brown corundum. White corundum is made of high quality aluminum oxide powder by electrofusion. Brown corundum is made of high-quality bauxite, anthracite and tiexiao. It is melted at a high temperature of more than 2000 degrees in the arc. It is crushed and shaped by the autogenous mill. Iron is removed by magnetic separation(black synthetic corundum wholesale supplier). It is divided into many kinds of particle sizes.(black synthetic corundum wholesale supplier)


The main factor affecting wear-resistant materials is chemical composition. Chemical corrosion wear can be divided into oxidation wear and special medium corrosion wear(brown aluminum oxide 24 grit). This repeated process of corrosion and wear is called corrosion wear. This wear is usually slight, but it can turn into severe wear in high temperature and humid environment. Erosion wear has become one of the causes of material damage in many industrial sectors(black synthetic corundum wholesale supplier).


It has dense texture, brown aluminum oxide high hardness and spherical shape. It is suitable for manufacturing ceramics, resin high consolidation abrasive tools, grinding, polishing, sandblasting, precision casting, etc(black synthetic corundum wholesale supplier). it can also be used for manufacturing high-grade resistance. Fire materials. This is also a better material made according to Chinese technical means. silicon carbide abrasive powder and brown corundum powder are mostly used as grinding paste.


Common types of grinding paste: white corundum grinding paste - mainly used for grinding iron and steel parts; black silicon carbide and boron carbide grinding paste - mainly used for grinding hard alloy, glass, ceramics and semiconductors; Chromium oxide grinding paste is mainly used for fine polishing or non-metallic grinding; diamond grinding paste is mainly used for green carborundum grinding and polishing of tungsten steel mold, optical mold, injection mold, etc(black synthetic corundum wholesale supplier).
