The invention relates to the technical field of alloys, in particular to an alloy connecting piece for an automobile seat adjuster and a forming process of the alloy connecting piece. The method specifically comprises the following steps that firstly, a grain refiner is prepared; and secondly, an aluminum ingot is melted, the intermediate alloy and a grain refiner are added into molten aluminum, casting is carried out to obtain an alloy connecting rough part, nitriding treatment is carried out on the alloy connecting rough part, and the alloy connecting part is obtained. The alloy connecting piece comprises the following raw materials of, by mass, 0.5%-1% of copper, 0.2%-0.6% of nickel, 0.2%-0.6% of manganese, 8%-11% of silicon, 0.02%-0.06% of strontium, 0.02%-0.04% of boron, 0.4%-1% of a grain refiner and the balance aluminum and inevitable impurities, and the impurities are smaller than or equal to 0.03%. Furthermore, the alloy comprises 0.6% of copper, 0.4% of nickel, 0.4% of manganese, 10.2% of silicon, 0.04% of strontium, 0.02% of boron and 0.8% of grain refiner.
