Pyrocoat FM-W is graphite-based, non-reflective, energy absorbing coating that is applied to the surface of aluminium prior to melting, typically in a dry hearth furnace. This coating reduces the reflectivity of the aluminium, thereby increasing the absorption of radiant heat into the aluminium. Non-coated aluminium naturally reflects heat from its bright surface, taking longer to melt than aluminium coated with Pyrocoat FM-W. Typical melting rate times have shown melt rates cut in half by coating the aluminium with Pyrocoat FM-W. Decreasing melt time has many advantages, including increased productivity and decreased energy usage.
