What is 711.0-F?
711.0-F is 711.0 in the F temper — freshly cast, un-aged stock; strength is noticeably lower and still rising, so use only when parts will be machined and then allowed to age before loading. 711.0-F has a yield strength of 125 MPa (18.1 ksi) and a tensile strength of 200 MPa (29 ksi) — weaker than 75% of aluminum grades. Elongation at break is 9% and the elastic modulus is 71 GPa (10.3 Msi). 711.0-F has a density of 2.84 g/cm³ (0.103 lb/in³), heavier than 93% of aluminum grades. It melts at 600°C (1,112 °F). T1 is the default condition FabDigit quotes; F is available on request or by drawing note.

Working with 711.0-F
Is 711.0 easy to machine?
Machines very well dry or with light lubricant — low Si means little tool wear, and the naturally aged T1 structure gives clean chips and good surface finish.
Can 711.0 be welded?
Poor fusion weldability: wide freezing range and Zn volatilization cause porosity and hot cracking; repair by mechanical means or use dedicated Al-Zn-Mg filler with strict preheat control.
Can 711.0 be formed, bent or molded?
Permanent-mold (metal-mold) casting alloy; fluidity is only fair and it is hot-tear sensitive, so use generous fillets, controlled mold temperature and directional solidification — not for cold forming.
What surface finishes work on 711.0?
Takes a good machined or polished surface and accepts sulfuric-acid anodizing with a slightly darker film; chromate conversion or paint is recommended for chloride exposure because of the anodic Zn-bearing matrix.
711.0 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

711.0-F — frequently asked
What is 711.0-F used for?
711.0-F is typically used for machine hardware, brackets and housings. In short: permanent-mold Al-Zn alloy; most ductile of the 7xx.x group; no quench distortion.
What is the yield strength of 711.0-F?
711.0-F has a typical yield strength of 125 MPa (18.1 ksi) and a tensile strength of 200 MPa (29 ksi) — weaker than 75% of aluminum grades. Strength varies by condition: see the 2 listed tempers.
Is 711.0-F easy to machine?
Reasonably — machinability is rated good (68/100, better than 67% of aluminum grades). Machines very well dry or with light lubricant — low Si means little tool wear, and the naturally aged T1 structure gives clean chips and good surface finish.
Can 711.0-F be welded?
Not readily — weldability is rated poor (30/100). Poor fusion weldability: wide freezing range and Zn volatilization cause porosity and hot cracking; repair by mechanical means or use dedicated Al-Zn-Mg filler with strict preheat control.
What surface finishes work on 711.0-F?
Takes a good machined or polished surface and accepts sulfuric-acid anodizing with a slightly darker film; chromate conversion or paint is recommended for chloride exposure because of the anodic Zn-bearing matrix.
Can 711.0-F be formed, bent or molded?
Permanent-mold (metal-mold) casting alloy; fluidity is only fair and it is hot-tear sensitive, so use generous fillets, controlled mold temperature and directional solidification — not for cold forming.
What is the maximum service temperature of 711.0-F?
711.0-F 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 711.0-T1 and 711.0-F?
T1 is the default condition — the standard and essentially only commercial condition: no furnace heat treatment, properties develop by room-temperature aging over ~2–3 weeks. F: freshly cast, un-aged stock; strength is noticeably lower and still rising, so use only when parts will be machined and then allowed to age before loading. Yield strength is 170 MPa in T1 versus 125 MPa in F.
