Aluminum alloy clad member adopted to heat exchanger, and core material for the same
View Patent ↗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.
1. An aluminum alloy clad material comprising:
a layer of the core material; and
a filler material layer clad on one or both sides of the core material layer,
wherein the filler material contains an Al—Si alloy, a Zn alloy, or a Sn alloy, and
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.
2. An automobile heat exchanger comprising the aluminum alloy clad material according to claim 1 .
3. An automobile brazed radiator tube comprising the aluminum alloy clad material as clamed in claim 1 .
4. 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
a sacrificial material layer clad on the other side of the core material layer,
wherein the filler material contains an Al—Si alloy, a Zn alloy, or a Sn alloy, and
wherein the sacrificial material contains an Al—Zn alloy, and
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.
5. An automobile heat exchanger comprising the aluminum alloy clad material according to claim 4 .
6. An automobile brazed radiator tube comprising the aluminum alloy clad material as clamed in claim 4 .
