Aluminum Alloy 319 T5
  • Alloy 319  is a 6Si-3.5 Cu alloy with 1.0 Fe (max) and 1.0 Zn (max). The T5 heat treatment is a thermal aging  at 310F .

  • Alloy 319 has good casting characteristics and machinability.

  • Typical applications for sand castings of 319 include internal combustion and diesel engine crankcases; gasoline and oil tanks; and oil pans.

The Alloy 319 has good ductility, hardness, fatigue strength, and machinability, but the alloy fails to meet the requirements for tensile strength, yield strength, pressure tightness, and fluidity.
