What does "T4" mean in the material of aluminum bar?
T4 represents the production process is quenching, Aluminum Alloy material of natural aging, usually is 2A12 grade aluminum rod
2, aluminum rod material label in T4 is the state subdivision grading after solution treatment for grade T4, T--- material for heat treatment after the state of the 4----, as the level state divided after heat treatment, T4 refers to the material after solution heat treatment, have natural aging to stable state not, after cold processing can be used directly.Note: solid solution treatment - heating allows all phases in the material to be fully dissolved, strengthens solid solution, improves toughness and corrosion resistance, and eliminates stress and softening.
1, aluminum is mostly heat treatment, but because of the application of different occasions, so the heat treatment of the material after the state is divided into T1~T10, a total of ten levels, called the state subdivision level, for different purposes.
