What is A535.0?
A535.0 is an Al-Mg7 casting alloy from the ANSI/AA 5xx.x family that reaches 275 MPa tensile, 125 MPa yield, 12% elongation and 65 HB in the as-cast F condition with no heat treatment. It is specified for corrosion resistance in marine and food-processing hardware, a machinability rating of 88, and bright polishing and anodizing response, as sand, permanent-mold (F-PM) and investment (F-IC) castings. Limits are foundry-side low fluidity and hot-tear sensitivity, 96 W/m·K conductivity and service to about 120 °C; A356.0-T6 casts more easily for thin, intricate parts. A535.0 has a density of 2.62 g/cm³ (0.0947 lb/in³), lighter than 96% of aluminum grades. It melts at 549°C (1,020 °F). A535.0 has a yield strength of 125 MPa (18.1 ksi) and a tensile strength of 275 MPa (39.9 ksi) — weaker than 75% of aluminum grades. Elongation at break is 12% and the elastic modulus is 70 GPa (10.2 Msi).

Working with A535.0
Is A535.0 easy to machine?
Machines very freely with sharp positive-rake tools and high speeds; gives clean chips and excellent surface finish with minimal built-up edge.
Can A535.0 be welded?
Readily GTAW/GMAW welded with 5356 or matching Al-Mg filler; use clean, dry surfaces and low heat input to limit Mg loss and porosity.
Can A535.0 be formed, bent or molded?
Foundry-critical alloy: melt under protective flux/cover gas, keep low turbulence gating with generous risers, and expect low fluidity plus hot-tearing risk in thin or restrained sections.
A535.0 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.

A535.0 — frequently asked
What is A535.0 used for?
A535.0 is typically used for marine hardware, food-processing equipment and decorative castings. In short: corrosion-resistant cast aluminum; free-machining as-cast; bright-anodizing casting alloy.
What is the yield strength of A535.0?
A535.0 has a typical yield strength of 125 MPa (18.1 ksi) and a tensile strength of 275 MPa (39.9 ksi) — weaker than 75% of aluminum grades. Strength varies by condition: see the 3 listed tempers.
Is A535.0 easy to machine?
Yes — machinability is rated excellent (88/100, better than 96% of aluminum grades). Machines very freely with sharp positive-rake tools and high speeds; gives clean chips and excellent surface finish with minimal built-up edge.
Can A535.0 be welded?
Yes — weldability is rated very good (70/100). Readily GTAW/GMAW welded with 5356 or matching Al-Mg filler; use clean, dry surfaces and low heat input to limit Mg loss and porosity.

Foundry-critical alloy: melt under protective flux/cover gas, keep low turbulence gating with generous risers, and expect low fluidity plus hot-tearing risk in thin or restrained sections.
What is the maximum service temperature of A535.0?
A535.0 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 A535.0-F and A535.0 F-PM?
F is the default condition — standard supply condition: sand-cast and used as-cast for corrosion-resistant, dimensionally stable, easily machined parts. F-PM: choose for higher-volume, thinner-section parts where the chill of a metal mould raises strength and refines the structure. Yield strength is 125 MPa in F versus 130 MPa in F-PM.
