ALUMINUM ALLOY HAVING SUPERIOR INTEGRATION CHARACTERISTIC

PURPOSE:To remarkably improve the integration strength of a conjugated material, by incorporating specific amounts of Be to an Al alloy at the time of manufacturing the conjugated material by joining an Mg-containing Al alloy to an Al alloy of the same kind or a dissimilar material such as ceramics and carbon. CONSTITUTION:At the time of manufacturing the conjugated material containing Al alloy by joining an Al-alloy material containing >=0.5% Mg to other Al alloys, ceramics materials, carbon materials, etc., a material prepared by adding and incorporating 0.01-1.0% Be to an Al alloy is used. By this method, the conjugated material in which the integration characteristic between the above- mentioned Al alloy and the opposite material to be combined with this Al alloy is improved and which has superior adhesive strength can be obtained.
