Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 496-2005 "brazed heat exchangers with aluminum foil."
Compared with this standard YS/T 496-2005, the main differences are as follows.
--- Increasing the term;
--- Increased 4004,4045,4047,4104,4343,4A13,4A43,4A45 alloy grades;
--- Original grade 3003 1% Zn to 3A11, the original designation 3003 1.5% Zn to 7A11;
--- Increasing the chemical composition of the alloy 4A43,4A45 requirements;
--- Increasing the width of aluminum foil;
--- Increase the mechanical properties of the alloy 4004,4045,4047,4104,4343,4A13,4A43,4A45;
--- Increasing the aluminum test methods;
--- Modified aluminum foil thickness, width tolerance.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
