Scandium Scarcity Slows Aerospace Aluminium Alloy Commercialization Timelines
A Critical Bottleneck in Advanced Alloy Development Scandium’s scarcity continues to frustrate the commercialization of high-performance aluminium-scandium alloys, a material class that aerospace manufacturers have long regarded as a step-change in structural efficiency. Despite well-documented engineering advantages, the supply chain for this rare element remains too thin, too concentrated, and too unpredictable to support the kind of industrial-scale procurement that
