"World's strongest aluminum alloy" made via spray forming.(METALS/POLYMERS/CERAMICS)

An aluminum alloy with a tensile strength of 780 MPa (113 ksi) has reportedly been developed by means of a spray forming process, reports Kobe Steel Ltd., Japan. With a breaking elongation of 14%, ductility is said to be nearly three times higher than that of Weldalite.

Zinc, magnesium, and copper are added to strengthen the material. In conventional melting and casting processes, when the amount of the alloy elements is increased, segregation develops during solidi
