Aluminum coil alloy temper

Aluminum coil alloy temper

H1 pure work hardening condition suitable for obtaining the desired strength by work hardening without additional heat treatment

H2 working hardening and incomplete annealing; Applicable to work hardening degree beyond the requirements of the finished product, after incomplete annealing, so that the strength of the specified index products.

State of H3 work hardening and stabilization; It is suitable for products with stable mechanical properties after work hardening after low-temperature heat treatment or due to the action of heat in the process of processing.

State of H4 work hardening and paint treatment; It is suitable for the products with incomplete annealing caused by paint treatment after work hardening.

The tensile strength limit of HX1 is the intermediate value between 0 and HX2 state, less than 10% déformation.

HX2 tensile strength limit is the intermediate value between 0 and HX4 state, 15% déformation (aussi connu sous le nom 114 hard worry state).

The tensile strength limit of HX3 is the intermediate value between HX2 and HX4 states.

HX4 tensile strength limit is the intermediate value between 0 and HX8 state, 35% déformation (also known asSemi-hard state).

The tensile strength limit of HX5 is the intermediate value between HX4 and HX6 states.

HX6 tensile strength limit is the intermediate value between HX4 and HX8 state, 55% deformation amount (aussi connu sous le nom 3/4 hard state)

The tensile strength limit of HX7 is the intermediate value of HX8 hard state between HX6 and HX8 state.
