The invention relates to an aluminium alloy, and aluminium alloy product consisting at least in part of an aluminium alloy, an ingot formed from an aluminium alloy, and also a method for producing an aluminium alloy. An improved soldering process is achieved by an AlSi aluminium alloy that has the following proportions of alloy components in percentage by weight: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%,the remainder being Al and unavoidable impurities, individually at most 0.05% by weight and in total at most 0.15% by weight, wherein the aluminium alloy is free from Si primary particles with a size of more than 10 μm.
