Different Tempers of 4043 Aluminum Bars
T4 Temper
- Description: Solution heat-treated and naturally aged. Provides a good balance of strength and ductility.
- Applications: Used where moderate strength and good machinability are required, often in components that are not subjected to extreme conditions.
T6 Temper
- Description: Solution heat-treated and artificially aged. Offers improved strength and hardness compared to the T4 temper.
- Applications: Suitable for high-performance applications requiring higher strength and hardness, such as aerospace and high-stress automotive parts.
As-Cast
- Description: The aluminum is in its original state as cast. It has good castability but lower mechanical properties compared to heat-treated tempers.
- Applications: Typically used for cast parts where no additional heat treatment is needed, providing good overall properties for less demanding applications.
