Title:

Al BASE ALLOY EXCELLENT IN HEAT RESISTANCE, WORKABILITY AND RIGIDITY

Document Type and Number:

WIPO Patent Application WO/2006/103885

Kind Code:

A1

Abstract:

Disclosed is a lightweight Al base alloy which is high in heat resistance and elongation characteristics at around 200-300&ring C while having excellent workability in hot working. Also disclosed is a heat-resistant Al base alloy which is excellent in wear resistance and rigidity. Specifically disclosed is an Al base alloy composed of, in mass%, 5-10% of Mn, 0.5-5% of V, 0.5-5% of Cr, 0.5-5% of Fe, 1-8% of Si, 0.5-5% of Ni and the balance of Al and unavoidable impurities. The Al base alloy structure is composed of 35-80% by volume of an intermetallic compound phase and a metal Al matrix constituting the remaining part of the alloy structure.
