AlBeCast 910®: High-Performance Al‑Be Composite for Superior Strength and Thermal Properties

Materion's AlBeCast® product line is a family of investment cast aluminum-beryllium metal matrix composites that provides designers a net-shape product. Advantages over aluminium A356.0:

~22% lower density

~3 times stiffer (modulus of elasticity in tension)

Up to 10 times better in damping coefficient

~40% lower in coefficient of thermal expansion (CTE)

~50% higher specific heat

~28% higher thermal conductivity

Advantages over beryllium:

~3 times greater ductility than hot pressed beryllium with greater damage tolerance

Castable for complex and precise net shape configurations

Weldable for defect repair

Reduced machining and scrap generation

Reduced environmental processing concerns resulting from reduced waste

Does not require chemical etching

Reduced material usage

Reduced cost
