Cover Flux

Cover fluxes are applied to the melt surface to form a physical cover and improve metal recovery. AMCOR can trace its roots back to the original development and formulation of cover fluxes for UBC recycling in the 1960s. Today, cover fluxes are used almost anywhere aluminum scrap is melted. Chemistry and particle sizing are critically important in cover fluxes in order to achieve the desired melting point and performance.

Tap Cones

Tap cones act as a plug to regulate the flow of molten metal from furnaces and ladles. AMCOR manufactures vacuum-formed tap cones designed to fit the size and shape of the mandrill and the tap hole block. Common sizes are in stock or available to order, while other custom sizes can be designed and produced to a target specification.
