What is 511.0?
511.0 is a low-alloy Al-Mg sand casting alloy at about 4% Mg (A05110), used in the as-cast F temper at roughly 83 MPa yield, 145 MPa tensile, 3% elongation and 50 HB. Engineers select it for corrosion resistance (rated 80), high machinability (85) and a surface that polishes and anodizes better than Al-Si castings, typically in sand-cast food, dairy and architectural hardware. Fluidity is poor with a high hot-tear and oxide-film tendency, so section design must be generous, and service is limited to about 120 °C at only 3% elongation. Choose 356.0 when castability or strength govern. 511.0 has a density of 2.65 g/cm³ (0.0957 lb/in³), lighter than 90% of aluminum grades. It melts at 588°C (1,090 °F). 511.0 has a yield strength of 83 MPa (12 ksi) and a tensile strength of 145 MPa (21 ksi) — weaker than 89% of aluminum grades. Elongation at break is 3% and the elastic modulus is 71 GPa (10.3 Msi).

Working with 511.0
Is 511.0 easy to machine?
Excellent — soft, non-gummy chips with sharp high-rake carbide/PCD tooling; gives clean bores and fine surface finish with minimal built-up edge.
Can 511.0 be welded?
Readily GTAW/GMAW welded with 5356 (Al-Mg) filler; preheat is unnecessary and repairs of castings are straightforward, but weld zone remains as-cast strength.
Can 511.0 be formed, bent or molded?
Sand casting only — poor fluidity and high hot-tear/oxide-film tendency require generous fillets, controlled pouring and flux/cover protection of the melt.
