Aluminium Oxide
Description:
Aluminium Oxide has the characteristics of high hardness, sharpness, tenacity, stable chemical properties, heat-resisting and corrosion-resisting. This abrasive is fast-cutting and does not contain free silica. It gives a matte finish or produces anchor patterns on most metal surfaces, and can be used economically in a closed system blasting machine.
Application
Removal of sand from casting or surface preparation prior to enamelling, Teflon coating, plating or bonding, etching, descaling, deburring, cleaning moulds, glass carvings and decorative works in the glasses industry.
