It’s the latest and most advanced Pre-Melt Specification Aluminum (PSA) product developed exclusively by Federal Metal as an alternative to more expensive prime and RSI (remelt secondary ingot). It comes from a single raw material input, utilizes a dry process, and has been proven to consistently meet the Aluminum Association’s 1100 chemical composition. We currently ship it in blocks (7 lb briquettes) or as granulated flake (fractions 1/16” to 1/2”). COMING SOON: additional product offerings.
