Titanium-Aluminum Alloy

Abstract

The invention relates to a titanium/aluminium alloy with an alloy composed of titanium, aluminium and niobium, with an aluminium content of between 35 and 60 wt. %. The alloy can further contain 1-100 ppm chlorine and/or fluorine and 0.01-1.0 wt. % gold and/or silver. The invention further relates to a lightweight component made from a titanium/aluminium alloy and the use of a titanium/aluminium alloy for the production of a homogeneous, fine-grain, precursor by means of a spin casting method.
