Direction of future development of alloy wheels
1. casting aluminum wheel: 1.1 casting aluminum wheel of material casting aluminum wheel used A356 casting aluminum grades, by melting casting, will solid of aluminum ingots into liquid of aluminum water, by pouring to mold type cavity, get aluminum wheel shape, again by solid dissolved quenching artificial limitation of heat treatment, makes manufacturing aluminum wheel of material mechanical performance strength can meet General passenger cars on wheel products of requirements. Cast aluminum-alloy wheels are the material requirements: tensile strength 260mpa 180mpa yield strength and elongation of 7% However, for casting reasons, due to cooling of castings have different will have mechanical properties vary greatly in different parts. Spoke of extending only below 4%, and the elongation of the rim is about 10%. Casting production of aluminum alloy wheel can only be used in passenger cars.
