Tungsten carbide (WC), also referred to as cemented carbide, is a composite material manufactured by a process called powder metallurgy. Tungsten carbide powder, generally ranging in proportion between 70%-97% of the total weight, is mixed with a binder metal, usually cobalt or nickel, compacted in a die and then sintered in a furnace.

2018/9/27· Carbide is unusually heavy, so if the metal in these types of objects seems heavy for its size, it could be carbide. You can try the magnet test (explained later) or a variety of other identifiion tests to get a better idea of whether your scrap metal is carbide.
About Abrasives for Sanding Wood
Silicon carbide abrasives stay sharp until they die, but they die relatively quickly. This makes it the least expensive option for belt sanders. There is only one kind of silicon carbide and it’s harder and sharper than most aluminium oxides, making it the best choice for cutting hard materials like wood finishes, paint, plastic and metal.
What is a carborundum Stone? - Sharpening
