What is 710.0-F?
710.0-F is 710.0 in the F temper — use for castings machined and put in service immediately after shakeout, before natural ageing has completed. 710.0-F has a yield strength of 125 MPa (18.1 ksi) and a tensile strength of 205 MPa (29.7 ksi) — weaker than 75% of aluminum grades. Elongation at break is 6% and the elastic modulus is 71 GPa (10.3 Msi). 710.0-F has a density of 2.81 g/cm³ (0.102 lb/in³), heavier than 86% of aluminum grades. It melts at 600°C (1,112 °F). T5 is the default condition FabDigit quotes; F is available on request or by drawing note.

Working with 710.0-F
Is 710.0 easy to machine?
One of the best-machining cast aluminium alloys — free-cutting chips, sharp corners and good finish at high speed with sharp carbide and light lubrication.
Can 710.0 be welded?
Poor fusion weldability; the high-Zn matrix is hot-crack and porosity prone, so repairs are usually mechanical rather than welded.
Can 710.0 be formed, bent or molded?
Sand casting only (permanent-mould use is served by 711.0); needs generous risering and controlled cooling to avoid hot tears, and gains strength without a solution-treat/quench cycle so distortion is minimal.
What surface finishes work on 710.0?
Machines and polishes well; anodizes to a fair, slightly dull clear film — paint or chromate/anodize plus sealing is advised for chloride environments to limit SCC risk.
710.0 chemical composition (wt %)

710.0-F — frequently asked
What is 710.0-F used for?
710.0-F is typically used for machinery parts, hardware castings and fittings. In short: best-machining cast aluminum; no solution treatment needed; sand-cast Al-Zn-Cu.
What is the yield strength of 710.0-F?
710.0-F has a typical yield strength of 125 MPa (18.1 ksi) and a tensile strength of 205 MPa (29.7 ksi) — weaker than 75% of aluminum grades. Strength varies by condition: see the 3 listed tempers.
Is 710.0-F easy to machine?
Yes — machinability is rated very good (80/100, better than 92% of aluminum grades). One of the best-machining cast aluminium alloys — free-cutting chips, sharp corners and good finish at high speed with sharp carbide and light lubrication.
Can 710.0-F be welded?
Not readily — weldability is rated poor (25/100). Poor fusion weldability; the high-Zn matrix is hot-crack and porosity prone, so repairs are usually mechanical rather than welded.
What surface finishes work on 710.0-F?
Machines and polishes well; anodizes to a fair, slightly dull clear film — paint or chromate/anodize plus sealing is advised for chloride environments to limit SCC risk.
Can 710.0-F be formed, bent or molded?
Sand casting only (permanent-mould use is served by 711.0); needs generous risering and controlled cooling to avoid hot tears, and gains strength without a solution-treat/quench cycle so distortion is minimal.
What is the maximum service temperature of 710.0-F?
710.0-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 710.0-T5 and 710.0-F?
T5 is the default condition — most commonly supplied condition — a short low-temperature age stabilises dimensions and locks in full strength without solution treatment or quench distortion. F: use for castings machined and put in service immediately after shakeout, before natural ageing has completed. Yield strength is 170 MPa in T5 versus 125 MPa in F.
