Foreword
GB/T 3880 "Wrought aluminium and aluminium alloy plates, sheets and strips for general engineering" is divided into the following 3 parts.
- Part 1. Technical conditions of delivery;
- Part 2. Mechanical properties;
- Part 3. Tolerances on forms and dimensions.
This Part is the first part of GB/T 3880.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009. This Part replaces GB/T 3880.1-2006 "Wrought Aluminium and Aluminium Alloy Plates, Sheets and Strips for General Engineering - Part 1. Technical
Conditions of Delivery".
Compared with GB/T 3880.1-2006, the main technical changes are as follows. - Add 31 alloy designations in total - 1070A, 1080A, 2017A, 2A12, 2A14, 2014A, 2E12 (previous. 2524), 2219, 3103, 3A21, 4006 , 4007, 4015,
5A02, 5005A, 5040, 5049, 5449 , 5050, 5251, 5154A, 5754, 5454, 5383,
6016, 7A04, 7A09, 7020, 7021, 7022, 7475, 8011 and 8079.
- The maximum thickness is expanded from 150 mm to 250 mm;
- The maximum width is expanded from 2500 mm to 3500 mm;
- Change the maximum thickness of cold-rolled plates, sheets and strips to 6 mm;
- Add requirements for conductivity;
- Add requirements for stress corrosion resistance;
- Add requirements for exfoliation corrosion resistance;
- Add requirements for fracture toughness;
- Add requirements for corrosion resistance to fatigue;
- Add requirements for macrostructure.
This Part uses redrafting method to modify and adopt EN 485-1.2008
"Aluminium and aluminium alloys - Sheet, strip and plate - Part 1. Technical conditions for inspection and delivery", and it is non-equivalent with EN 485- 1.2008.
This Part shall be under the jurisdiction of National Standardization Technical Committee on Nonferrous Metals (SAC/TC 243).
Main drafting organizations of this Part. Southwest Aluminum (Group) Co., Ltd., China Nonferrous Metals Industry Institute of Standards Metrology and Quality, Northeast Light Alloy Co., Ltd., Chalco Ruimin Co., Ltd, Xiamen Xiashun Aluminum Foil Company Limited, Northwest Aluminum Fabrication Company,
Zhenjiang Ding Sheng Aluminum Co., Ltd AND Fujian Nanping Aluminium
Sheet and Strip Co. Ltd.
