Aluminium alloy is one of the most commonly used structural materials in the world. It is used for a variety of applications including automotive, aerospace and engineering structures. Aluminium alloy is light weight, strong and provides excellent corrosion resistance and fatigue resistance.
Aluminium alloy has a high strength-to-weight ratio and is an excellent choice for high-performance applications. Due to its strength, excellent corrosion resistance and relatively low cost, aluminium alloy is an ideal material for use in engineering applications. To improve the strength of aluminium alloys, additional elements such as magnesium and manganese are added to the alloy. This is known as the heat-treatable process, which is used to produce aluminium alloys with higher strength than pure aluminium.
One of the highest strength aluminium alloys is 7068-T6 aluminium alloy. 7068-T6 aluminium alloy has a high yield strength of 523 MPa, ultimate strength of 614 MPa and a high level of fatigue resistance and crack propagation resistance. 7068-T6 aluminium alloy is widely used in the aerospace industry due to its high strength and fatigue resistance properties. It is also used for components in automotive, transport and engineering structures.
7068-T6 aluminium alloy is an aluminium-zinc-magnesium-copper alloy with excellent dimensional stability, excellent weldability and corrosion resistance. The composition of 7068-T6 aluminium alloy is; 4.4% copper, 1.2% magnesium, 4.0% manganese, 1.2% silicon and 0.2% zinc and the remainder is aluminium. 7068-T6 aluminium alloy is commonly heat-treated to increase its strength, making it one of the strongest aluminium alloys available.
Heat-treatable 7068-T6 aluminium alloy contains high levels of manganese and magnesium, which provide a strong grain refinement effect, increasing the strength of the alloy. Heat-treatable 7068-T6 aluminium alloy can be formed using standard cold or warm working processes. The strength of this alloy is best achieved using a combination of solution heat-treat and rapid cooling, quenching and tempering.
The strength of 7068-T6 aluminium alloy makes it ideal for applications where high strength is required, such as aircraft structures, automotive and transportation components, as well as engineering components. It also offers excellent electrical and thermal conductivity, strong weldability and good ductility and formability.
In conclusion, 7068-T6 aluminium alloy is the highest strength aluminium alloy available with a high level of fatigue resistance and corrosion resistance. It is the ideal material for applications that require high strength and durability. Its high strength and light weight makes it an ideal choice for automotive, aerospace and engineering components and structures.
