Working with A535.0 F-IC
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.
What surface finishes work on A535.0?
Outstanding bright polishing and clear/colour anodising; chromate or trivalent conversion coatings and paint adhere well, but avoid flux brazing and Hg-bearing chemicals.

A535.0 F-IC — frequently asked
What is A535.0 F-IC used for?
A535.0 F-IC 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 F-IC?
A535.0 F-IC has a typical yield strength of 125 MPa (18.1 ksi) and a tensile strength of 265 MPa (38.4 ksi) — weaker than 75% of aluminum grades. Strength varies by condition: see the 3 listed tempers.
Is A535.0 F-IC 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 F-IC 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.
What surface finishes work on A535.0 F-IC?
Outstanding bright polishing and clear/colour anodising; chromate or trivalent conversion coatings and paint adhere well, but avoid flux brazing and Hg-bearing chemicals.
Can A535.0 F-IC 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.
What is the maximum service temperature of A535.0 F-IC?
A535.0 F-IC 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.
