The invention belongs to the technical field of automobile alloy production, provides a high-strength aluminum alloy light truck girder, raw material components thereof and a heat treatment process ofthe high-strength aluminum alloy light truck girder, and belongs to the technical field of automobile alloy production. The frame comprises a left longitudinal beam, a right longitudinal beam, a first cross beam assembly, a second cross beam assembly, a third cross beam assembly, a fourth cross beam assembly, a fifth cross beam assembly, a sixth cross beam assembly and a seventh cross beam assembly. The aluminum alloy frame consists of the following components in percentage by mass: 0.001%-0.05% of silicon; 0.04%-0.35% of zirconium; 4.0%-9.0% of zinc; 0.001%-0.6% of iron; 0.001%-0.45% of manganese; 1.0%-4.0% of magnesium; 1.0%-3.0% of copper; 0.001%-0.20% of impurity elements; and metal aluminum. The materials are subjected to water quenching treatment, natural aging treatment and manualaging treatment, so that a finished product can be obtained. The frame provided by the invention has the advantages of simple structure, convenient disassembly and the assembly, light weight, small pollution, and effectively improved transportation economic benefits.
