Kind Code:
A1
Abstract:
Disclosed is a frame for a two-wheeler or all-terrain vehicle, the frame being composed of a plurality of aluminum members constituted of a high-strength 7000-series aluminum alloy. The frame has reduced susceptibility to weld cracking and includes weld joints having excellent strength properties. A 7000-series aluminum alloy for giving a plurality of aluminum members is regulated so as to have an alloy composition containing 0.01-0.50% Cu, 0.5-2.1% Mg, and 4.0-8.5% Zn, with the remainder being Al and incidental impurities, and the aluminum members formed therefrom are united by welding to produce a frame for a two-wheeler or all-terrain vehicle, using a filler metal having an alloy composition containing 5.5-8.0% Mg, 0.05-0.25% Cr, up to 0.25% Ti, up to 0.4% Si, up to 0.4% Fe, up to 0.1% Cu, up to 0.05% Zr, and up to 0.25% Zn, with the remainder being Al and incidental impurities.
