This beryllium aluminum alloy provides an ideal solution for weight, stiffness and thermal critical applications in aerospace, defense and commercial markets. BeAl-363 is a metal matrix composite which consists of 65% Be (by weight) and 35% Al.

BeAl-363 is used primarily for high-strength/high-elastic modulus precision cast structural applications. This alloy is 22% less dense than Al-356 and is 3.5 times as stiff.
