Abstract
A core material for an aluminum alloy clad material contains Si in a content of 0.3% to 1.5% (hereinafter “%” means “percent by mass”), Mn in a content of 0.3% to 2.0%, Cu in a content of 0.3% to 1.5%, Ti in a content of 0.01% to 0.5%, and B in a content of 0.001% to 0.1%, with the remainder including Al and inevitable impurities. The core material and an aluminum alloy clad material using the same ensure sufficient corrosion resistance and give a product having an extended life.
Claims6

- wherein the core material consists of:
- silicon (Si) in a content of 0.3 to 1.5 percent by mass,
- manganese (Mn) in a content of 0.3 to 2.0 percent by mass,
- copper (Cu) in a content of 0.3 to 1.5 percent by mass,
- titanium (Ti) in a content of 0.01 to 0.5 percent by mass,
- boron (B) in a content of 0.001 to 0.1 percent by mass, and
- calcium (Ca) in a content of 1.0 percent by mass or less (excluding 0%)
- with the remainder including aluminum (Al) and inevitable impurities.
An aluminum alloy clad material comprising
- a layer of the core material;
- a filler material layer clad on one side of the core material layer;
- and
