Good quality Black Fused Aluminum Oxide Grains for Sale

good quailty black fused aluminum oxide grains for sale   Black aluminum oxide fused corundum is also known as low aluminum corundum. It is also a new type product of polishing material, and it is a dark gray crystal body made α-Al2O3 and ferropicotite as main ore in the electric arc furnace by smelting the bauxite. It has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability. It is mainly suitable for free grinding, such as coarse grinding before electroplating products, mainly for polishing and sandblasting of stainless steel, fabricated metal products.Black Fused Alumina Chemcal AnalysisChemical Composition (% by weight)Range of GritsChemical CompositionAl2O3   SiO2     Fe2O3   TiO224#-100#  8511 5.0 1.5-3.5120#-200#  75-81 9-12 4-6 2-3240#-280#  64107.0 1.5-3.0  Black Fused Alumina physical propertiesHardness (Mohs)    ≥ 9.0Melting point (°C)  2050The maximum temperature (°C)    1850True Density (g/cm3)    ≥ 3. 50Linear expansion coefficient (0-1600 °C)     7-9High content industry calcined black fused alumina ApplicationApplication1. Extremely hard, sharp, and durable abrasive2. Angular shape and fairly high bulk density will produce a matte surface finish3. Abrasive is generally reusable many times because of its hardness and durability4. Anchor pattern creation prior to coating or bonding5.Rust, scale, or other tough contaminant removal6. Application must tolerate some metal removal7.
