6056 Aluminium Alloy Used in Cars

6056 Aluminum is an Al-Mg-Si-Cu alloy widely used in the automotive and aviation fields. Its strength is 15% higher than that of 6061 aluminum alloy. Its weldability, corrosion resistance and cutting performance are better than 7075 and 2024 alloy.

6056 aluminum alloy has complex chemical compositions. During the semi-continuous casting process, the ingot structure will deviate from the equilibrium state, resulting in severe dendrite segregation and a large amount of non-equilibrium solidification eutectic structure.

Therefore, 6056 aluminum alloy ingot must be homogeneously annealed to eliminate dendrite segregation, while dissolving the non-equilibrium solidified eutectic structure of the alloy into the matrix, minimizing the residual crystalline phase in the matrix, and improving the plasticity of the alloy. Homogenization annealing treatment is one of the key point to obtain mechanical properties.

Machinery applications: It is used to those parts where moderate to high strength, good toughness, weldability and lighter weight are required.

Transportation applications: It is used to manufacture structural parts where higher strength and toughness than conventional 6xxx series alloys are required.

In recent years, as global warming and energy problems have become serious, lightweight car has become a common sense of most countries. The lightweight car can help to reduce energy consumption, reduce pollution, and improve fuel economy. T

The related data shows that every 100 kg reduction of the car, fuel consumption can be reduced by 0.7 L/km. Therefore, minimizing the weight of the car has become a hot research topic. Aluminum alloy is one of the ideal lightweight material due to its low density and satisfying strength.
