American Metal Chemical

Rossborough Supply was founded in 1942 by chemist Alexander Rossborough to develop, manufacture and supply specially formulated chemical compounds called fluxes to aluminum foundries. AMCOR has grown considerably over the years and currently manufactures products in four locations; Medina, Ohio; Lorain, Ohio; Chicago, Illinois; and Florence, Alabama. AMCOR's philosophy is to maintain diligent cost controls while providing consistent, quality products. Additionally, AMCOR's focus is to develop products for an increasingly wide range of melting and casting industries. The industries served include primary and secondary aluminum processing, rolled products, dross processing, extrusion and billet, aluminum, magnesium and zinc die casting and gray iron and steel foundries.
