The invention discloses a casting technology for a front-axle beam of an automobile steering axle. The front-axle beam of the steering axle is prepared from raw materials in percentage by weight as follows: 0.22%-0.38% of Mg, 1.2%-2.4% of Cu, 0.1%-0.3% of Cr, 0.2%-0.44% of Mn, 0.3%-0.6% of Si, 0.08%-0.12% of Ni, 0.08%-0.12% of Ti, 0.3%-0.52% of Li, 0.4%-0.6% of nano-carbide, 0.8%-1.0% of rare earth element RE and the balance of Al. The front-axle beam of the automobile steering axle is high in strength, good in corrosion resistance and long in service life. 本发明公开了种汽车转向桥的前梁铸造工艺，所述转向桥前梁的原料按照如下重量百分含量配料：Mg：0.22-0.38%、Cu：1.2-2.4%、Cr：0.1-0.3%、Mn：0.2-0.44%、Si：0.3-0.6%、Ni：0.08-0.12%、Ti：0.08-0.12%、Li：0.3-0.52%、纳米碳化:0.4-0.6%、稀土元素RE:0.8-1.0%，余量为Al。本发明的汽车转向桥的前梁强度高、耐蚀性好、使用寿命长。
