Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 439-2001 "aluminum and aluminum alloy extruded flat stick" compared with YS/T 439-2001, the main technical change
as follows.
--- Increased alloy classification. It is about 2 ×××, 7 ××× alloys and magnesium content ≥3.0% average of 5 ××× alloy into
A class (referred to as the hard alloy type), is another type of other alloys (referred to soft alloys);
--- Increased 1350,2014,2014A, 2017A, 3102,3103,5005,5005A, 5051A, 5251,5019,5049,5154A,

--- The maximum thickness of the product expanded from the original 150mm to 240mm;
--- Resistivity index of the original 6101 alloy requirements into the conductivity indicator;
--- Increasing the angular deviation of the requirements in size deviations;
--- Increased porosity in low magnification, the compound and the oxide film between the bright grains, non-metallic inclusions, segregation or metal compounds
Regulations defects.
