What is 713.0-F?
713.0-F is 713.0 in the F temper — freshly cast condition before natural aging completes; used when parts will be machined immediately or aged in service. 713.0-F has a yield strength of 110 MPa (16 ksi) and a tensile strength of 180 MPa (26.1 ksi) — weaker than 81% of aluminum grades. Elongation at break is 6% and the elastic modulus is 71 GPa (10.3 Msi). 713.0-F has a density of 2.81 g/cm³ (0.102 lb/in³), heavier than 86% of aluminum grades. It melts at 595°C (1,103 °F). T5 is the default condition FabDigit quotes; F is available on request or by drawing note.

Working with 713.0-F
Is 713.0 easy to machine?
Machines well in T1/T5 with sharp carbide tooling, high speed and light cuts; chips are short and surface finish is better than for high-Si Al-Si castings.
Can 713.0 be welded?
Fusion welding is only fair — use 4043 or 5356 filler, preheat sparingly, and expect a local strength drop in the HAZ that partially recovers by natural re-aging.
Can 713.0 be formed, bent or molded?
Sand and permanent-mold casting alloy of moderate fluidity and above-average hot-tear tendency; generous fillets, chills and good risering are needed, but no solution treatment or quench is required.
What surface finishes work on 713.0?
Takes paint, chromate conversion and protective anodizing well; decorative bright anodizing is poor and grey because of the high Zn/Cu, and salt-spray exposure requires an applied coating.

713.0-F — frequently asked
What is 713.0-F used for?
713.0-F is typically used for automotive castings, pump housings and machinery components. In short: pressure-tight cast aluminum; no solution treatment required; fair weldability for 7xx.x.
What is the yield strength of 713.0-F?
713.0-F has a typical yield strength of 110 MPa (16 ksi) and a tensile strength of 180 MPa (26.1 ksi) — weaker than 81% of aluminum grades. Strength varies by condition: see the 3 listed tempers.
Is 713.0-F easy to machine?
Reasonably — machinability is rated good (65/100, better than 62% of aluminum grades). Machines well in T1/T5 with sharp carbide tooling, high speed and light cuts; chips are short and surface finish is better than for high-Si Al-Si castings.
Can 713.0-F be welded?
With care — weldability is rated fair (45/100). Fusion welding is only fair — use 4043 or 5356 filler, preheat sparingly, and expect a local strength drop in the HAZ that partially recovers by natural re-aging.
What surface finishes work on 713.0-F?
Takes paint, chromate conversion and protective anodizing well; decorative bright anodizing is poor and grey because of the high Zn/Cu, and salt-spray exposure requires an applied coating.
Can 713.0-F be formed, bent or molded?
Sand and permanent-mold casting alloy of moderate fluidity and above-average hot-tear tendency; generous fillets, chills and good risering are needed, but no solution treatment or quench is required.
What is the maximum service temperature of 713.0-F?
713.0-F is rated for continuous use to about 120°C (248 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 713.0-T5 and 713.0-F?
T5 is the default condition — standard commercial condition: a short low-temperature age stabilises dimensions and gives full strength without solution treatment or quench distortion. F: freshly cast condition before natural aging completes; used when parts will be machined immediately or aged in service. Yield strength is 152 MPa in T5 versus 110 MPa in F.
