Types of carbide scrap, grouped the way a shop makes them

Most carbide is made into cutting tools. The National Toxicology Program puts it at about 70% of hard-metal production for cutting tools and 30% for wear-resistant parts, mainly tools for mining and grinding.

USGS sorts the scrap itself into hard scrap, which is solid pieces such as cemented carbide parts, and soft scrap, the fine particles such as grinding sludges, loose powders and swarf. Our pages follow the same line:

A mixed bucket is fine to send as it is. Sorting it first, as our sorting guide shows, lets us quote each part of the lot on its own.

The exotic metals that end up in the same boxes

Carbide is what we came for, but we also buy all exotic metals and alloys: tungsten, titanium, nickel and cobalt alloys, tantalum, niobium, molybdenum and high-speed steel. In OSHA's scrap recycling guidance, exotic metals (cobalt, titanium, tungsten and the like) sit under nonferrous metals. Keep them in their own bags, and see metals we buy for each one.

Carbide and exotic metals sell to us the same way. Sellers anywhere in the US can ship to us and we pay the shipping, and in every city in California, Arizona, Utah and Nevada we can come and pick it up. We pay cash where state law allows. Send photos and a rough weight through the quote form, email help@carbidebuyersusa.com, or call (877) 899-5778.
