Steering wheel |
摘要 |
A one-piece steering wheel is formed as a unitary casting from an alloy that includes 11.5% to 14% by weight silicon, and 350 to 450 parts per million strontium. Preferably the steering wheel mold is rotated during casting at relatively high rotational speeds exerting 100 g to 250 g force on the wheel. An optimum rotational speed is disclosed. A one-piece steering wheel formed according to the invention exhibits minimal length ferro-silicon hair-like strands, and thus exhibits reduced brittleness.
