    Beryllium’S AdvantagesBeralcast® MaterialBeralcast® in The F-35 Lightning II FighterNear-Net Shape CastingBeryllium is simply an amazing metal. It is the second lightest metal after lithium, but is also as stiff as steel. In fact, its modulus of elasticity is 50% greater than steel. It has a very high melting point (1,287°C) and a low density (1.844 g/cm3). It resists oxidation and corrosion in the air.When alloyed with aluminum, copper, and other metals, beryllium’s application in aerospace and other applications really begins to shine.For one, the low coefficient of thermal expansion (CTE) prov...
