2618 heat-resistant aluminum alloy is an Al-Cu-Mg series alloy that introduces the appropriate content of Fe and Ni elements to introduce the intermetallic compound phase Al9FeNi phase. This alloy is a heat-treatable alloy, which is widely used in the aerospace industry and the automotive industry because of its good high-strength, light-weight performance and heat resistance.



2618 heat-resistant aluminum alloy wire rod, its chemical composition (mass fraction, the same below): Cu is 2.63%, Mg is 1.59%, Fe is 1.11%, Ni is 1.08%, Si is 0.13%, Mn is 0.15%, Ti < 0.1%, Zη <0.1%, other impurities content <0.05%, the rest is aluminum
Measures and means to improve the strength and heat resistance of 2618 heat-resistant aluminum alloy reduce the plasticity and toughness of the alloy to varying degrees. Therefore, it is an inevitable trend to fully tap the potential of 2618 heat-resistant aluminum alloy wire rod and to greatly improve the strength and heat resistance of the alloy on the basis of ensuring its room temperature plasticity and toughness, and it has strong practical significance and use value.

2618 heat-resistant aluminum alloy wire rod is generally used for molds and hand forgings, high temperature operation pistons and aircraft engine rotating parts, tire molds.
