What is 513.0?
513.0 (A05130) is an Al-Zn-Mg permanent mold casting alloy in the ANSI/AA 5xx.x series, formerly designated A514.0, that develops its properties by natural ageing rather than heat treatment. As-cast F temper gives 185 MPa tensile strength, 110 MPa yield, 7% elongation and 60 HB, with 138 W/m·K conductivity, making it useful for gravity die-cast hardware and housings that must resist corrosion and machine freely. Maximum service temperature is 100 °C, and castability is the main constraint: fluidity is poor and hot-tear sensitivity is high. For sand-cast parts in the same corrosion class, 514.0 is the closer choice. 513.0 has a density of 2.68 g/cm³ (0.0968 lb/in³), lighter than 72% of aluminum grades. It melts at 582°C (1,080 °F). 513.0 has a yield strength of 110 MPa (16 ksi) and a tensile strength of 185 MPa (26.8 ksi) — weaker than 81% of aluminum grades. Elongation at break is 7% and the elastic modulus is 71 GPa (10.3 Msi).

Physical3
513.0 has a density of 2.68 g/cm³ (0.0968 lb/in³), lighter than 72% of aluminum grades. It melts at 582°C (1,080 °F).
Mechanical11
513.0 has a yield strength of 110 MPa (16 ksi) and a tensile strength of 185 MPa (26.8 ksi) — weaker than 81% of aluminum grades. Elongation at break is 7% and the elastic modulus is 71 GPa (10.3 Msi).
Thermal6
513.0 is rated for continuous service to 100°C (212 °F). It conducts heat at 138 W/m·K (79.7 BTU/hr·ft·°F), worse than 55% of aluminum grades. Thermal expansion is 23.9 µm/m·K (13.3 µin/in·°F).
Electrical3
513.0 conducts electricity at 34 % IACS, worse than 52% of aluminum grades.
Chemical & Environmental3
Corrosion resistance is very good (75/100), better than 88% of aluminum grades.
Sustainability4
Producing a kilogram of 513.0 takes about 200 MJ of energy and emits 12 kg of CO₂ — less than 60% of aluminum grades. Typical recycled content is 55%.
Manufacturability8
513.0's machinability is very good (78/100, better than 89% of aluminum grades); weldability good (65/100); formability poor (15/100).

Working with 513.0
Is 513.0 easy to machine?
Machines very freely with sharp polished-flute carbide tooling and generous rake; chips are long and gummy, so use high speed, flood emulsion and chip breakers.
Can 513.0 be welded?
GTAW/GMAW with 5356 (Al-5Mg) filler gives sound repairs; preheat sparingly and avoid restraint because the high-Mg matrix is hot-crack sensitive.
Can 513.0 be formed, bent or molded?
Permanent-mold (gravity die) casting only — poor fluidity and strong hot-tear tendency demand generous fillets, controlled mold temperature and well-fed risers; melt must be protected against Mg oxidation/dross.
513.0 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.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| Si | ≤ 0.3 | |
| Fe | ≤ 0.4 | |
| Cu | ≤ 0.1 | |
| Mn | ≤ 0.3 | |
| Mg | 3.5 – 4.5 | 4 |
| Cr | ≤ 0.35 | |
| Zn | 1.4 – 2.2 | 1.8 |
| Timax, grain refiner | ≤ 0.2 | |
| Others (each) | ≤ 0.05 | |
| Others (total) | ≤ 0.15 | |
| Al | balance |
What surface finishes work on 513.0?
Outstanding for bright clear and colour anodizing and for mechanical polishing; chromate/chrome-free conversion coatings and paints adhere well without heat treatment.
