Abrasive Sanding Belts 3M Trizact – Aluminium Oxide. Macro replicated abrasive structures are designed to cut faster at higher pressures. Controlled mineral breakdown delivers more consistent, predictable finishes over the life of the abrasive. Geometric "bricks" wear evenly throughout service life due to multiple layers of mineral. Ideal for Stainless Steel, Titanium, Zirconium, High Nickel Alloy and Carbon Steel.
