Product description

Technical data

Mixed alumina type WIWOX® RK has a low ferrite content and is particularly suitable for applications where a high consumption of blasting abrasives cannot be avoided. Mixed Alumina is produced from ceramic grinding wheels and reclaimed alumina dust from the blasting and grinding industry. It consists of a mixture of white, pink and brown alumina, and is an iron-free alternative for many sectors of the blasting and grinding industry.
