ScBeMo

ScBeMo is an experimental scandium–beryllium–molybdenum alloy that combines the lightweight properties of beryllium with scandium's strengthening effects and molybdenum's high-temperature stability. This ternary system is primarily a research-phase material investigated for applications where extreme weight savings and thermal performance are critical, though it remains limited to specialized aerospace and defense programs due to beryllium's manufacturing complexity and toxicity constraints. The alloy represents an advanced materials strategy for pushing performance envelopes in weight-critical structures, competing against titanium aluminides and nickel superalloys where beryllium toxicity and cost can be justified by mission requirements.
