What is 713.0?
713.0 (A07130, ZC81A) is an Al-Zn-Cu sand and permanent-mold casting alloy with good as-cast strength and pressure tightness, reached without solution heat treatment. It suits automotive castings, pump housings and machinery components that must hold fluid pressure and be machined: 152 MPa yield, 210 MPa tensile, 4% elongation, 75 HB, 140 W/m·K and 30% IACS, in F, T1 and T5. Weldability is only fair, hot-tear tendency is above average, and service is capped near 150 °C. 711.0 is the more ductile choice when pressure tightness is less critical. 713.0 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). 713.0 has a yield strength of 152 MPa (22 ksi) and a tensile strength of 210 MPa (30.5 ksi) — weaker than 64% of aluminum grades. Elongation at break is 4% and the elastic modulus is 71 GPa (10.3 Msi).

Working with 713.0
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 — frequently asked
What is 713.0 used for?
713.0 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?
713.0 has a typical yield strength of 152 MPa (22 ksi) and a tensile strength of 210 MPa (30.5 ksi) — weaker than 64% of aluminum grades. Strength varies by condition: see the 3 listed tempers.
Is 713.0 easy to machine?
Yes — machinability is rated very good (72/100, better than 80% 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 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?
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 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?
713.0 is rated for continuous use to about 150°C (302 °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.
How much does 713.0 cost?
713.0 is a standard-cost aluminum ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
