COATED AND NON-WOVEN ABRASIVES Coated Abrasive Basics
Coated Abrasives A coated abrasive product is made up of three basic raw materials: an abrasive grain, the backing onto which the abrasive is applied, and an adhesive bond.
Abrasive Types Emery (6) Emery is a dark gray, round-shaped grain which tends to polish rather than abrade a work surface. • For polishing and cleaning metal only Garnet (5) Garnet is reddish brown in color. This natural abrasive is medium hard and relatively sharp, but not as durable as synthetic abrasives. • For use on wood only • Particularly good for soft woods such as pine
Heat-treated Aluminum Oxide (2) Heat-treated aluminum oxide is a tough but cool cutting abrasive which gives both long life and freeness of cut on a wide range of materials.
• Ferrous metals • Wood sanding Zirconia Alumina (8)
Zirconia alumina is an ultra-tough, synthetic abrasive which provides a free, cool cut for high stock removal applications. It is tougher and sharper than aluminum oxide. It has a micro-crystalline structure which
allows for controlled breakdown and self-sharpening. • Heavy-duty snagging and grinding of all ferrous and non-ferrous metals • Abrasive planing of wood, plywood and particleboard • Grinding fiberglass, rubber and plastics Ceramic Alumina (9)
• Produces an excellent finish Silicon Carbide (4)
Silicon carbide is the hardest and sharpest of the manufactured abrasives. Because of its extreme sharpness, this bluish-black abrasive grain permits fast stock removal and cool cut. • Cast iron • Non-ferrous metals, i.e. brass, aluminum and bronze • Non-metallics, i.e. glass, rubber, plastic and stone • Final finish on wood and stainless steel • Abrasive planing particleboard Light Brown Aluminum Oxide (2) Light brown aluminum oxide is a tough, yet sharp synthetic abrasive characterized by cool cut, long life and the ability to break down under pressure, producing new cutting edges.
The sub-micron structure of ceramic alumina allows each grain to continually expose sharp cutting points, resulting in a cooler cutting action and an extended life. • All ferrous/non-ferrous metals, carbon steel and exotic alloys Engineered Shaped Ceramic (9) Engineered shaped ceramic grain features a consistent shape from grain to grain along with razor-sharp cutting points. The unique patented geometry and tough micro-structure enable the grain to stay sharp, as new cutting points are exposed when the
grain fractures. • Carbon steel • Aluminum • Stainless steel • Hard-to-grind metals
• Production wood sanding • Non-ferrous metal finishing Brown Aluminum Oxide (2, 7)
Brown aluminum oxide is a tough, durable, synthetic abrasive characterized by the long life and wear resistance of its cutting edges. It offers enormous penetrating strength, even at high speeds. • Ferrous metals
• Aluminum • Hardwood
