Document Type and Number:
Japanese Patent JP7217091
Kind Code:
B2
Abstract:
A method and alloys for low pressure permanent mold casting without a coating are disclosed. The method includes preparing a permanent mold casting die that is devoid of die coating or lubrication along the die surface, preparing a permanent mold casting alloy, pushing the alloy into the die under low pressure, cooling the permanent mold casting, and removing the casting from the die. One alloy has 4.5-11.5% by weight silicon; 0.45% by weight maximum iron; 0.20-0.40% by weight manganese; 0.45-0.110% by weight strontium; 0.05-5.0% by weight copper; 0.01-0.70% by weight magnesium; and the balance aluminum. Another alloy has 4.2-5.0% by weight copper; 0.005-0.45% by weight iron; 0.20-0.50% by weight manganese; 0.15-0.35% by weight magnesium; 0.045-0.110% by weight strontium; 0.50% by weight maximum nickel; 0.10% by weight maximum silicon; 0.15-0.30% by weight titanium; 0.05% by weight maximum tin; 0.10% by weight maximum zinc; and the balance aluminum.
