|---|---|---|---|---|---|---|

Permanent (chill) mould cast, as-cast | Choose chill casting for thinner walls, finer grain and roughly 10–15 % higher strength and ductility than sand casting. | 105 | 195 | 7 | 55 HB | 35 % IACS |
What is EN AC-51300?
EN AC-51300 (AlMg5, 514.0) is a medium-magnesium, non-heat-treatable Al-Mg sand and gravity casting alloy from the EN 1706 family, used in S-F and K-F condition. It balances corrosion resistance, the best machinability and surface finish of the cast aluminum alloys (score 78) and moderate strength — 170 MPa tensile, 95 MPa yield, 5% elongation, 50 HB, 146 W/m·K — with good weldability (score 72). Service temperature is limited to about 100 °C and foundry practice is demanding because of modest fluidity and hot-tearing risk. Choose EN AC-51100 AlMg3 for easier casting or EN AC-51200 AlMg9 for higher strength. EN AC-51300 has a density of 2.65 g/cm³ (0.0957 lb/in³), lighter than 90% of aluminum grades. It melts at 600°C (1,112 °F). EN AC-51300 has a yield strength of 95 MPa (13.8 ksi) and a tensile strength of 170 MPa (24.7 ksi) — weaker than 86% of aluminum grades. Elongation at break is 5% and the elastic modulus is 71 GPa (10.3 Msi).

Working with EN AC-51300
Is EN AC-51300 easy to machine?
Machines cleanly with the best surface finish of the cast Al alloys — sharp polished carbide, high speed, low feed, minimal built-up edge; use emulsion or MQL.
Can EN AC-51300 be welded?
Good TIG/MIG weldability with ER5356/AlMg5 filler; preheat only lightly (<120 °C), avoid Al-Si fillers and prolonged heat to prevent grain-boundary β-phase sensitization.
Can EN AC-51300 be formed, bent or molded?
Foundry-critical alloy: fluidity is modest and hot-tear/oxide-film tendency high — needs melt cover/flux protection, low pouring temperature (~700–730 °C), generous risering and Ti grain refinement; not heat treatable, used as-cast.
EN AC-51300 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.

What surface finishes work on EN AC-51300?
Outstanding for clear, bright and colour anodizing and mechanical polishing; also takes chromate-free conversion coatings and paint — mask Mg-rich oxide by good pre-cleaning.
