| 摘要 |
The invention refers to an aluminium alloy, a clad or unclad material for brazed products containing said alloy as a core, as well as a method of producing materials to be used in brazed products from said alloy. The material is suitable for controlled atmosphere brazing (CAB). The alloy comprises 0.6-0.9 wt% silicon, 0.1-0.35 wt% magnesium, 0.4-0.7wt% manganese, 0,1-0.25 wt% titanium, 0.25-0.35 wt% copper, and optionally 0.05-0.25 wt% zirconium, the balance consisting of aluminium and unavoidable impurities. The method for producing the material comprises the steps of subjecting said alloy to a casting process and subjecting the cast alloy to hot rolling and a cold rolling process, possibly followed by an annealing process. |
