Washington Mills Electro Minerals Corporation

Washington Mills is a leading manufacturer of abrasive grains, fused minerals, and specialty materials serving manufacturers and industrial customers worldwide.

Washington Mills is a leading manufacturer of abrasive grains, fused minerals, and specialty materials serving manufacturers and industrial customers worldwide. Founded in 1868, Washington Mills is one of the world’s largest producers of abrasive grain and fused mineral products, with significant manufacturing operations in Niagara Falls and Tonawanda, NY.

Washington Mills manufactures a broad range of engineered mineral grains and powders, including brown fused aluminum oxide, white fused aluminum oxide, silicon carbide, boron carbide, alumina-zirconia, fused mullite, fused zirconia-mullite, fused spinel, chrome alumina, fused magnesium oxide, fused calcium aluminate, alumina bubbles, ferro silicon, fused silica, ceramic grains, and other specialty fused materials.

The company utilizes electric arc fusion and Acheson furnace technologies to transform raw materials into high-performance industrial minerals with controlled chemistry, purity, particle size, density, shape, and other material properties. Products are available in a wide range of macrogrit, microgrit, powder, and custom particle sizes to meet specific customer and application requirements.

Washington Mills materials are used in abrasive blasting, grinding wheels, coated abrasives and sandpaper, lapping, polishing, surface preparation, refractories, advanced ceramics, metal preparation, coatings, semiconductor and electronics manufacturing, metallurgy, steel production, aerospace, infrastructure, oil and gas, pipelines, shipbuilding, and numerous other industrial applications.

In addition to standard materials, Washington Mills provides custom material and new product development services. Its Research & Development team can conduct pilot-scale custom fusions and milling to help customers develop new materials, evaluate formulations, improve existing products, and scale successful concepts toward commercial production.

Laboratory and material testing services include chemical and physical analysis, X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), particle characterization, and other analytical capabilities used to control material chemistry, purity, crystal structure, and performance.

Washington Mills also provides closed-loop recycling for spent aluminum oxide. Used aluminum oxide can be returned to the manufacturing process and fused into new material, helping manufacturers reduce waste and support sustainability and circular manufacturing initiatives.
