| 摘要 |
This application discloses a multilayer aluminum material having an aluminum alloy core and aluminum alloy cladding, wherein the aluminum alloy cladding contains 0.1-1.0 wt% Cu, 0.1-0.5 wt% Fe, 0.1-1.0 wt% Mn, 3-15 wt% Si, 0.005-0.15 wt% Ti and 0.1-7 wt% Zn, remainder Al. The aluminum alloy cladding can also optionally contain one or more of 0.001-0.3 wt% Mg, 0.001-0.01 wt% Ni or 0.001-0.05 wt% of at least one of Sr, Ca or Na. A process for producing the material is also described. The material can be produced in sheet form and is suitable for brazing application. The metal forms fabricated from the multilayer aluminum material comprising brazing steps are also described. |
