Zhigu's aftermarket alloy wheels blend performance and affordability, using A356-T6 cast aluminum with T6 heat treatment to achieve 220 MPa tensile strength. The low-pressure casting process ensures uniform density, while CNC machining provides precise tolerances (±0.1mm). Available in 15-22" sizes with 5-10 lug patterns, they feature a 12-step finishing process including e-coat primer, powder coat, and clear coat for 500-hour salt spray resistance. These wheels are 15% lighter than steel OEM alternatives, improving fuel efficiency and handling. Load ratings range from 1,500 to 3,000 lbs per wheel, suitable for daily drivers to light-duty trucks.
