Title:
ALUMINUM ALLOY FOR FORGING HAVING SUPERIOR STRENGTH AND COLD FORGEABILITY
Document Type and Number:
Japanese Patent JPS60174845
Kind Code:
A
Abstract:
PURPOSE: To obtain the titled non-heat-treatment type Al alloy by adding prescribed amounts of Mg, Zn, Cu, Ti and B to Al.
CONSTITUTION: This Al alloy consists of, by weight, 4.0W<6.0% Mg, 0.5W2.0% Zn, 0.05W0.8% Cu, 0.001W0.10% Ti, 0.0001W0.01% B and the balance Al or further contains one or more among ≤0.3% Zr, ≤0.3% Cr, ≤1.0% Mn and ≤0.01% Be. The alloy is a non-heat-treatment type Al alloy having about 30kg/mm2 tensile strength and higher strength and cold forgeability than 5056 alloy as a non- heat-treatment type Al alloy. This Al alloy can be used as the material of a rod or a coil of a small diameter such as a metallic fitting of a brake horse for an automobile in place of iron by extrusion.
