Title:
ALUMINUM ALLOY FILLER MATERIAL AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3219293
Kind Code:
B2
Abstract:
PURPOSE: To obtain the aluminum alloy filler material which improves the strength of welding joint part while improving the crack resistance against Al-Zn-Mg based aluminum alloy filler material at the same time.
CONSTITUTION: This filler material contains 1-6% Zn, 3-6% Mg (here, Zn≤Mg). 0.2-0.9% Mn, 0.05-0.5% Cr, 0.05-0.2% Ti, 0.01-0.2% B, and 0.05-0.2% Zr, and balance composed of Al and inevitable impurities. As necessary, further 0.02-1% Al may be incorporated. Such filler material is produced by re-melting an aluminum cast ingot having the above-mentioned chemical composition cast with a conventional method by using the energy beam having the high power density of 104-109w/mm2 and the zone melting method that the melting width of one time is made ≤30mm, and rapidly solidifying by the solidifying speed of higher than 1-3×102°C/sec, and Zr may be incorporated more than the quantity the of solid solution.
