High-Purity Extrusion Grade Stock Reaches Mainstream Converters
High-purity impact extrusion grade aluminum slugs, which use engineered low-impurity alloy formulations designed to minimize tooling wear and defect formation throughout the forming process rather than relying on conventional commercial grade architecture alone, have moved from niche premium aerosol brands into mainstream tube and collapsible packaging converters since 2023 as high-purity production costs declined enough to reach smaller regional converters worldwide. This documented forming advantage addresses genuine tooling wear concerns that standard commercial grade slugs alone could never satisfy, particularly as converters began requiring certified purity ratings for feedstock renewal programs this cycle. The same pull shows up in the aerosol packaging market, where MMA projects a 4.8% CAGR through 2036.
Market Impact: Adds 4% consumption driven demand
