Foreword
This standard was drafted in accordance with the rules given in GB/T
1.1-2009.
This standard replaces GB/T 6892-2006 “Wrought aluminum and aluminum
alloys extruded profiles for general engineering”. As compared with GB/T
6892-2006, the main technical changes of this standard are as follows.
- DELETE the vehicle profiles;
- DELETE the original appendix A, Appendix B and Appendix C;
- ADD the 6008, 6360, 7021 alloy;
- ADD the H111 state of 2014, 2014A, 2024, and 6082 alloys;
- MODIFY the mechanical properties of 2017 alloy;
- ADD the 0 and H111 state of 5005 and 5005A alloy;
- ADD the T1 state of 6005 alloy;
- MODIFY the performance of 6005 and 6005A alloy under T5 state;
- ADD the T66 state of the 6063 and 6060 alloy;
- In respect of the profile mechanical property limit value of T4 state of 2A11
and 2A12 alloy, the T5 state of 6261 alloy, and the T6 state of 7A04 alloy,
SPECIFY the maximum wall thickness of the applicable profile;
- ADD the surface treatment profiles of anodizing, anodizing +
electrophoretic coating, powder spraying and liquid spraying.
This standard was proposed by China Nonferrous Metals Industry Association.
This standard shall be under the jurisdiction of the National Nonferrous Metals
Standardization Committee (SAC/TC 243).
