Title:
HIGH PRESSURE CAST ALUMINUM ALLOY EXCELLENT IN STRENGTH AND TOUGHNESS AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH09143605
Kind Code:
A
Abstract:
To produce a high pressure cast Al alloy for an automobile 2 piece or 3 piece wheel disk having improved strength and toughness compared to those of the conventional casting alloy and low in cost compared to that of a forging and to provide a method for producing the same.
This aluminum alloy has a compsn. contg., by weight, 0.6 to 1.0% Si, 0.8 to 1.2% Mg, 0.1 to 0.5% Cu, 0.4 to 1.2% Zn, 0.4 to 1.2% Mn, 0.01 to 0.20% Ti and 0.002 to 0.04% B, and the balance Al with inevitable impurities. Furthermore, the method for producing the high pressure cast aluminum alloy for a wheel disk in which the molten metal of the above alloy is filled into a mold and is thereafter solidified under ≥500kgf/cm2 is provided.
