HIGH TOUGHNESS ALUMINUM-ALLOY CASTING AND ITS PRODUCTION METHOD

PROBLEM TO BE SOLVED: To provide a high toughness Al-alloy casting in which all of tensile strength, 0.2% proof stress and elongation can be obtained at high levels in a well balance. SOLUTION: The high toughness Al-alloy casting contains, by mass, 2 to 4% Si, 0.2 to 0.5% Mg, 0.4 to 0.8% Cu, 0.1 to...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a high toughness Al-alloy casting in which all of tensile strength, 0.2% proof stress and elongation can be obtained at high levels in a well balance. SOLUTION: The high toughness Al-alloy casting contains, by mass, 2 to 4% Si, 0.2 to 0.5% Mg, 0.4 to 0.8% Cu, 0.1 to 0.4% Zr, and the balance Al with inevitable impurities. The casting has the tensile strength of ≥280 MPa, the 0.2% proof stress of ≥220 MPa, and the elongation of ≥10%. COPYRIGHT: (C)2006,JPO&NCIPI
