2017-T4 Aluminum Round Bar
2017-T4 is a type of 2000 series aluminum alloy, primarily based on aluminum and copper. In the T4 temper, the alloy undergoes solution heat treatment and natural aging. This treatment provides excellent ductility (allowing for high machinability) and sufficient strength for demanding applications. It is widely used in the aerospace industry, automatic screw machine work, and other high-stress environments.
- Temper (T4) process: Solution heat treatment (heated to ~500°C, then quenched) and natural aging at room temperature.
- 2017-T4 Aluminum provides a balance of strength and ductility. The strength is lower than T6 (artificial aging), but its formability and machinability are better.
- Machinability and finishing: The T4 temper not only offers high ductility but also facilitates excellent machining, drilling, and forming operations. Protective surface treatments can be applied to enhance corrosion resistance in harsh environments.
In summary, the 2017-T4 aluminum round bar is a high-performance material that combines:
- Carefully controlled chemical composition (rich in copper and magnesium) to improve strength.
- T4 temper provides high ductility and ease of machining. Mechanical properties suitable for critical structures and high-stress applications.
The combination of these characteristics makes 2017-T4 an excellent choice for applications where both lightweight design and mechanical strength are crucial.
