Advantages and disadvantages of aluminum alloy control arms

The advantage of the aluminum alloy control arm is that it is durable, lightweight and the aluminum is corrosion resistant. the aluminum control arm has the following three advantages over the iron control arm.

• The strength of aluminum control arm is higher than that of iron control arm, and aluminum is less prone to rust than iron, so the service life of aluminum control arm is longer.

• The density of aluminum is lower than that of iron. In the same size, the weight of aluminum is much smaller than that of iron, which can make the car more fuel-efficient and easier to control.

• And the metal ductility of aluminum is better than that of iron, which can make the car more comfortable to ride.

Jiahangaero said that the disadvantage of aluminum control arms is that it is much more difficult to manufacture than iron control arms, so, usually, the price will be much higher than iron control arms.

Because aluminum has more advantages, high-end cars usually use aluminum alloy control arms to improve comfort, and super sports cars use aluminum suspensions to improve handling. However, the cost of the aluminum alloy swing arm is relatively high, so it will not be used in ordinary small family cars.
