What is the difference between automobile steel ring and aluminum alloy ring ?
1. Different production costs: the production cost of steel ring is low, the process is relatively simple, and it is less difficult to repair after deformation; Aluminum alloy ring, with complex processing technology, is easy to break after impact and difficult to repair.
2. Different weight: aluminum ring has good rigidity and light weight. Compared with the aluminum ring, the steel ring is much heavier.
3. Different hardness: the high density of steel ring leads to heavy mass, which leads to the amplification of tire dynamic balance buffeting at high speed Heavy mass leads to large driving resistance during cold start, increasing fuel consumption during start-up; Aluminum alloy ring: it has high hardness and lighter quality than steel ring. When the car is running at high speed, the tire dynamic balance jitter is smaller than steel ring, and the fuel consumption is smaller than steel ring at start-up.
