We used aluminum oxide mineral for our Scotch-Brite Cut and Polish Disc, which is a popular mineral choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
Our Scotch-Brite industrial abrasives are a unique surface conditioning product with abrasives incorporated into non-woven nylon or other synthetic fibers. Combining abrasives into the fibers creates an abrasive system that delivers consistent results for the life of the product. The open-web material is load resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the fibers.
