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. - Diameter mm: 125, 150, 180, 200, 230, 250, 300, 350, 400, 450, 500 - Thickness mm: 0.5, 0.8, 1, 1.5, 1.6, 1.8, 2, 2.5, 2.8, 3, 3.5, 4, 4.5 - Available holes (mm): 16, 20, 22, 25.4, 30, 32, 40, 51, 76 - Available grits: 60, 80, 100, 120 - Also available on request in the reinforced version (80m/s) - High performance extra version (type AMC) also available on request STANDARD SERIES HARDNESS TABLE - Metals to be cut / hardness: Impa reference - Ferrous metals <15 HRC (soft material): A60N – A60P - Ferrous metals 30-50 HRC (medium soft material): A60M – A60L - Ferrous metals 50-58 HRC (medium hard material): A60K - Ferrous metals 60-70 HRC (hard material): A60J – A60G - Ferrous metals 70 HRC (very hard material): A80F - Non-ferrous metals (cast iron, bronze, copper, aluminum): AC60J – AC60K - Non-ferrous metals (titanium): AC80G/T - Non-ferrous metals (stone, granite, marble): C60K - Diameter range: 125 mm to 500 mm - Thickness range: 0.5 mm to 4.5 mm (see table for combinations) - Available holes: 16, 20, 22, 25.4, 30, 32, 40, 51, 76 mm - Available grits: 60, 80, 100, 120 - Standard and reinforced versions available - High performance AMC type available on request
