Foreword
This standard adopts, through modification, ASTM B 85-03 “Standard
specification for aluminum-alloy die castings”. As compared with ASTM B 85-
03, this standard has the following differences in the main technical contents.
- It made large editorial changes in the structure;
- It did not adopt the reference documents in clause 2 of ASTM B 85-03, but
adopted the relevant Chinese standards;
- It did not adopt the finished product dimensional tolerance and performance
requirements of casting after processing in clauses 10 and 11 of ASTM B
85-03;
- It did not adopt the acceptance criteria for casting raw materials in Appendix
A of ASTM B 85-03;
- It added Appendix B and Appendix C.
This standard replaces GB/T 15114-1994 “Aluminum alloy die castings”.
As compared with GB/T 15114-1994, the main technical contents of this
standard are as follows.
- ADD the chemical composition table for casting materials;
- ADD the material grade YZAlSi10Mg (YL101), DELETE the material grade
YZAlSi12Cu2 (YL108);
- MODIFY the acceptance requirements for mechanical properties;
- ADD the reference value for mechanical properties of die castings in
Appendix A;
- ADD the additional amount when the line size is affected by the parting
surface in Appendix B;
- ADD the additional amount when the line size is affected by the active part
of the mold.
Appendix A, Appendix B, Appendix C and Appendix D of this standard are
informative appendixes.
This standard was proposed by the China Machinery Industry Federation.
