Aluminum extrusion is a process in which a block of aluminum alloy, called a "billet," is heated and then pushed through a die to create a specific shape. The shape of the die determines the shape of the extruded product.
Extruded aluminum is used in a wide range of products, including window frames, door frames, and structural components for buildings, as well as in manufacturing consumer goods such as appliances, electronics, and automobiles.
The 2020 alloy is a type of aluminum alloy often used in manufacturing various structures and parts, including industrial extruded profiles. It is known for its high strength-to-weight ratio and good machinability.
It is composed of aluminum (91-95%) and a small amount of copper (1-2%), manganese (0.5-1.2%), and magnesium (0.5-1.0%). The alloy is available in different tempers, such as T3, T4, and T6, which affect its strength and other properties.
The strength of the 2020 aluminum alloy depends on various factors, such as the specific alloy used, the temper of the material, and the manufacturing process. In general, the strength of the 2020 alloy is relatively high. The 2020 alloy typically has a tensile strength of around 45,000 psi or 310 MPa.
However, this value can vary depending on the specific alloy composition and the temper of the material. For example, the T6 temper, which is solution heat-treated and artificially aged, has the highest strength of the 2020 alloy tempers, while the T3 temper, which is solution heat-treated and cold worked, has the lowest strength but the highest flexibility.
It's important to note that tensile strength is just one measure of the strength of a material, and other properties such as yield strength, compressive strength, shear strength, fatigue strength, and impact strength are also important, depending on the specific application.
As mentioned above, the 2020 alloy is available in several different tempers, which affect its mechanical properties and suitability for different applications. The most common tempers for 2020 alloy are:
This temper is known as "solution heat-treated, and then cold worked." The alloy is first heated to a high temperature to dissolve any solid solution-hardening constituents. Then it is cooled rapidly to lock in the desired properties.
After that, the alloy is cold-worked, which means it is subjected to plastic deformation at a low temperature. This process increases the flexibility of the alloy and improves its formability.
The T3 temper has the lowest strength and highest flexibility of the 2020 alloy tempers and is well suited for cold forming and bending operations.
This temper is often used in applications that require good formability, such as electrical components, structural members, and machinery parts. It has the softest temper and the highest flexibility, making it well-suited for cold forming and bending operations.
The T4 temper is also known as "solution heat-treated and then naturally aged. “The alloy is first heated to a high temperature to dissolve any solid solution-hardening constituents. Then it is cooled rapidly to lock in the desired properties. After that, the alloy is left to age naturally at room temperature. This process increases the strength and hardness of the alloy.
The T4 temper has a higher power than the T3 but still has good ductility and formability. This temper is often used in applications that require a balance of strength and formability, such as automotive parts, structural members, and machine components. It has a higher power than T3 temper but still has good ductility and formability.
This temper is also known as "solution heat-treated and then artificially aged." The alloy is first heated to a high temperature to dissolve any solid solution-hardening constituents. Then it is cooled rapidly to lock in the desired properties. After that, the alloy is aged at an elevated temperature to strengthen the alloy further.
This process increases the strength of the alloy and improves its resistance to stress-corrosion cracking. The T6 temper is the strongest of the 2020 alloy tempers and is often used in applications that require high strength and toughness, such as aerospace components, aircraft fittings, and truck and bike frames. It has the highest power of the three tempers but lower ductility and formability.
The 2020 aluminum alloy is considered to be a strong material for several reasons:
In addition, the strength of 2020 aluminum alloy can be further increased through cold working processes, such as rolling or drawing, which increases the density of dislocations in the alloy and thus increases its strength.
Other tempers like T5, T42, T8, T9, T10, T11 and T12 are also available. Each temper has specific mechanical properties and is used in specific applications. It is important to note that the specific properties of 2020 alloy in different tempers may vary depending on the specific alloy composition and manufacturing process.
