White corundum

The white corundum for industry is manufactured from bauxite. calcined, in electric arc furnace. The prepared blocks of bauxite are subjected to temperatures around 2100 ºC in presence of some reducer and flux. The blocks have been removed from the are crushed and then screened. This type of corundum has great application in sandblasting of materials as stainless steel, bronze, brass, aluminium, zamack, compositions aeronautics in titanium, etc. This grain abrasive has the advantage that practically doesn't have Fe2 O3, so it's suitable in these alloys to avoid ferrous contaminations. This material can be used as for sandblasting than for shot blasting both in suction as well as in pressure. It has no free silica and does not contain carcinogenic or toxic components. There may be slight variations of one or more components. The material is manufactured under Fepa standard. This is also manufacturers under military standard for the aeronautical industry. Total quality control is available by inspecting: particle size, shape of the material, etc. grain, composition and resistance. Supplied in 25 kg multi-layer paper bags. The pallets are 1.000 Kg. It is recommended to store on pallets, in a dry place, protected from rain and humidity.
