Brown Fused Alumina for Coated Abrasives
The significant chemical composition of brown fused alumina is aluminum trioxide (Al2O3). Brown fused alumina is made by electric arc furnace smelting under high temperature with the raw materials of bauxite, anthracite and scrap iron. It is characterized by high hardness, toughness, and abrasion resistance.
The brown fused alumina P grain has a more aggregative distribution than the F grain, with sharpness and evenly distributive features, bringing more efficiency for surface treatment. Brown fused alumina P grain is widely used in coated abrasive such as abrasive cloth, abrasive paper, abrasive belts, etc.
Brown Fused Alumina for Coated Abrasives（FAQ）
What is porosity?
Porosity is defined as the gas proportion (cavity volume) of a particle’s total volume. It can be determined using different measurement techniques, such as gas adsorption and mercury porosimetry. With the same grain size and shape, a lower bulk density corresponds to a higher porosity of the grains.
What is your terms of payment?
T/T 30% as deposit, and 70% before delivery. We’ll show you the photos of the products and packages .before you pay the balance.
What is mohs hardness?
Mohs hardness (according to Friedrich Mohs, 1773 – 1839) ascribes a relative hardness value to certain known minerals on a scale ranging from 1 (talc) to 10 (diamond). Accordingly, a mineral is considered harder than another if it can scratch the latter. Please note that these values merely form an
What is the grit type?
Grit type is either aluminum oxide (white, pink, ruby red, brown, grey, etc.) silicon carbide (black or green), ceramic (blue and pink) or any combination of these. Grit types are sometimes mixed in combination for achieving certain cutting characteristics. Aluminum oxide is friable (white) or semi-friable (pink, brown and grey, red,
What is the warranty policy?
Firstly, We make sure the quality before the goods to be packed, if clients get the item with Substandard products, We have warranty for our clients,we will ship out the new replacements.
