ALUMINUM ALLOY FREE OF SI PRIMARY PARTICLES

摘要

The invention relates to an aluminum alloy, to an aluminum alloy product at least partially composed of an aluminum alloy, to a bar made of an aluminum alloy, and to a method for producing an aluminum alloy. The aim of providing an AlSi aluminum alloy that ensures an improved soldering process is achieved by means of an AlSi aluminum alloy that has the following fractions of alloying elements in weight percent: 4.5% = Si = 12%, P = 10 ppm, B = 10 ppm, 30 ppm = Ti = 240 ppm, Fe = 0.8%, Cu = 0.3%, Mn = 0.10%, Mg = 2.0%, Zn = 0.20%, Cr = 0.05%, remainder Al and unavoidable contaminants, no more than 0.05 wt% individually, no more than 0.15 wt% in total, wherein the aluminum alloy is free of Si primary particles having a size greater than 10 µm.
