By utilizing new casting technical process, the 22nd China Metallurgical Construction Group (22MCC Group) successfully completed the 20-inch super-hard aluminum alloy wheel on October 11, 2014. As the very first aluminum alloy product made by 22MCC Group, it marks that 22MCC Group has fully mastered the forging technology for aluminum alloy and successfully enter into the aluminum alloy forging field.
Such wheel is designed with the largest diameter of 630mm, with the weight of 65kg, and can be formed by pre-forging and final-forging. It is suitable for production by 120MN multi-cored forging press in terms of product material, size and production technology. It enjoys a huge market demand, and is the latest target product developed by 22MCC Group. In comparison with the traditional casting process, the strength of the aforesaid wheel is twice stronger than that of the common one, with 20% lesser of weight, and sufficient strength could be maintained even that the thickness could be greatly reduced. This type of wheel is featured by not only density uniformity, smooth surface, thin wall and light weight, but also endurance for greater pressure.
