1060 aluminum alloy belongs to the pure aluminum series, with an aluminum content typically above 99.6%. Among various aluminum alloys, 1060 aluminum has relatively low strength, but its excellent corrosion resistance and good formability make it widely used in many fields. Especially in the H18 temper, 1060 aluminum alloy undergoes strong cold working, resulting in higher hardness and strength.
H18 refers to the temper obtained through intense cold working (such as stretching, rolling, etc.). In the case of 1060 aluminum alloy, H18 indicates that the material has undergone a high degree of cold working, resulting in higher hardness and strength. Compared to the H16 temper, H18 has a higher hardness, approaching the strength of harder aluminum alloys, but its formability is somewhat reduced. This means that higher forces may be required during the forming process, but its physical properties will be superior to those of aluminum alloys in lower cold worked states.
