Abstract
The present invention provides a corrosion resistant aluminum-based alloy consisting of a compound which has a composition represented by the general formula: EQU Al.sub.a M.sub.b Mo.sub.c Hf.sub.d Cr.sub.e wherein: PA1 M is at least one metal element selected from Ni, Fe and Co and a, b, c, d and e are atomic percentages falling within the following ranges: 50%.ltoreq.a.ltoreq.88%, 2%.ltoreq.b.ltoreq.25%, 2%.ltoreq.c.ltoreq.15%, 4%.ltoreq.d.ltoreq.20% and 4%.ltoreq.e.ltoreq.20%, the compound being at least 50% by volume composed of an amorphous phase. The aluminum-based alloys not only have a high degree of hardness, strength and heat resistance but also exhibit a significantly improved corrosion resistance.
