Metallographic cutting discs (63m/s-80m/s) resin bond

In the field of cutting off metallographic specimens, IMPA ABRASIVI establishes itself with its abrasive discs among the best national and foreign leaders, the result of continuous research into highly selected raw materials from the best corundum producers available on the world market.

Our experience, which now takes advantage of 60 years of continuous analyses, has allowed us to develop abrasive cutters suitable for any material in the metallographic field (from highly alloyed steels to particular alloys, cast iron, titanium, etc.). With the formulation of these discs, a fast, precise cut is obtained which allows the structure of the specimen not to be altered or overheated. 

The choice of the right disc, depending on the material to be sectioned, is essential in order to obtain a perfect analysis of the metallographic specimen. Specialized technicians will be at your complete disposal for any need you may have regarding our products.
