Claims
- 1. A brazing sheet composite, comprising:
- (a) an aluminum core alloy material; and
- (b) a filler alloy cladding, applied to the core alloy material, consisting essentially of about 4 to 18 wt. % silicon; about 0.173 to 0.64 wt. % magnesium; about 0.01 to 0.3 wt. % lithium; not more than about 2 wt. % zinc; not more than about 1.25 wt. % manganese; not more than about 0.30 wt. % iron; not more than about 0.10 wt. % copper; not more than 0.15 wt. % impurities; balance aluminum.
- 2. The brazing sheet composite of claim 1 wherein said core material has at least one major surface area and the cladding is applied to the surface area.
- 3. The brazing sheet composite of claim 2 wherein the cladding comprises a thickness ranging from about 5 to 20% of the total thickness of the composite sheet.
- 4. The brazing sheet composite of claim 1 wherein the core material has at least two major surface areas and the cladding is applied to both of the surface areas.
- 5. The brazing sheet composite of claim 4 wherein the cladding comprises a thickness ranging from about 5 to 20% of the total thickness of the composite sheet.
- 6. The brazing composite of claim 1 wherein the core material is selected from the group consisting of the Aluminum Association 1XXX, 3XXX, 5XXX, and 6XXX series aluminum alloys.
- 7. The filler alloy of claim 1, wherein the magnesium content ranges from about 0.2 to 0.4 wt. %.
- 8. A filler alloy for brazing, consisting essentially of: about 4 to 18 wt. % silicon; about 0.190 to 0.64 wt. % magnesium; about 0.01 to 0.3 wt. % lithium; not more than about 2 wt. % zinc; not more than about 1.25 wt. % manganese; not more than about 0.30 wt. % iron; not more than about 0.10 wt. % copper; not more than 0.15 wt. % impurities; balance aluminum.
- 9. The filler alloy of claim 8, wherein the magnesium content ranges from about 0.190 to 0.508 wt. %.
- 10. The filler alloy of claim 8, wherein the magnesium content ranges from about 0.2 to 0.4 wt. %.
- 11. The filler alloy of claim 8, wherein the magnesium content is about 0.4 wt %.
