This closed coat aluminum oxide abrasive comes in a range of grades for common applications like repairing metal finishes, removing rust, deburring, blending and surface preparation for paints and coatings. From the Manufacturer The desired length of the strip can be torn from the roll for a specific application. The aluminum oxide abrasive can be used on ferrous and non-ferrous metals, wood, and plastic. The light J-weight cloth backing provides the flexibility needed to conform to circular edges, angles, or other contours. It remains durable even when bent or rolled, without tearing or shelling. On the other hand, the cloth can be torn by hand when a smaller piece is needed, without compromising the sanding surface. Aluminum oxide is a popular 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. The sanding surface is closed-coat, meaning that the abrasive mineral covers 100% of the sanding surface, for maximum cutting efficiency. Tough aluminum oxide abrasive mineral cuts fast and performs well on metal Flexible cloth backing makes a good general purpose abrasive for dry sanding Closed coat construction provides a consistent, fine finish Glue bond yields uniform, fine finishes in dry applications Available in grades from 80 to 500 and make-to-order converted forms
