Washington Mills 150 years

History of Fused Minerals

Established in 1868, Washington Mills was the first abrasive producer in the United States. Through its commitment to the industry and its goals of internal growth and strategic acquisitions, Washington Mills offers the broadest selection of abrasive grain and specialty electro-fused mineral products available in the market today.


Fused Mineral Properties

We manufacture many of our fused materials through an electric arc fusion process or Acheson furnace technology. The fusion process transforms raw materials such as bauxite, silica sand and alumina into materials such as aluminum oxide, silicon carbide, zirconia, mullite and many other fused materials. These abrasive and fused materials possess properties that make them valuable in hundreds of different applications.
