abradant

Abradant refers to any material, typically a hard substance, that is used to abrade, or wear away, another surface through friction. This process is fundamental to various manufacturing and finishing operations. Abradants are characterized by their hardness, particle size, shape, and chemical inertness, which influence their effectiveness and suitability for specific applications. Common examples include sand, emery, diamond, silicon carbide, and aluminum oxide. These materials can be used in a loose form or bonded to a substrate, such as in sandpaper, grinding wheels, or abrasive cloths. The choice of abradant depends on the material being worked and the desired outcome, ranging from coarse grinding to fine polishing. The abrasive action occurs when the harder abradant particles cut or scrape away material from the softer workpiece surface. Abrasion is a crucial technique for shaping, smoothing, cleaning, and preparing surfaces in industries like metalworking, woodworking, and stone cutting.
