Linsy A413 is a hypereutectic aluminum-silicon die casting alloy prized for its exceptional fluidity and pressure tightness. Highly resistant to hot tearing, it provides good corrosion resistance and is an ideal choice for intricate, thin-walled parts. A413 is primarily used in the as-cast condition and requires no heat treatment for its strength.
Available forms: ingot / die casting / sand casting / permanent-mold casting / CNC-machined cast parts
Common tempers: F (as-cast)
Processing support: CNC machining / polishing / anodizing / heat treatment
Quality documents: MTC report with every order

Linsy supplies A413 in the forms most useful for foundries and component buyers. Standard and custom dimensions are available; contact our team for non-listed sizes.
| Form | Typical Size / Specification | Common Use |
|---|---|---|
| Die casting | Per drawing; wall 0.8–5 mm | Intricate thin-wall dies |
| Sand casting | Per drawing | Lower-volume parts |
| Permanent-mold casting | Per drawing | Structural components |
| CNC-machined casting | Tolerances per ISO 2768 | Finished parts |
The tables below list the alloy’s common commercial and standard designations. Cross-references follow widely used naming systems; verify the exact designation required for your target market.
| System | Designation |
|---|---|
| Former / trade style | A413 |
| AA (Aluminum Association) | A413 |
| EN | EN AC- series (market dependent) |
| ASTM | ASTM B26 / B85 (castings), B179 (ingot) |
Composition limits below follow common casting-alloy standards. Values are weight percent, balance aluminum. Confirm exact limits against your required specification.
| Element | Content (wt.%) |
|---|---|
| Si | 11.0–13.0 |
| Fe | 2.0 max |
| Cu | 1.0 max |
| Mn | 0.35 max |
| Mg | 0.10 max |
| Zn | 0.50 max |
| Ni | 0.50 max |
| Others, each | 0.05 max |
| Others, total | 0.15 max |
| Al | Remainder |
The values below are typical room-temperature properties for the indicated condition and should be confirmed against mill test data for your specific casting and heat treatment. Casting method, section thickness, and cooling rate affect results.
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|
| F (as-cast) | 240–295 | 130–155 | 1.5–3.5 |
Choose the temper based on your priority between strength, ductility, and dimensional stability:
| Temper | When to Use |
|---|---|
| F (as-cast) | As-cast, no heat treatment. Best economy and dimensional stability for die and sand castings. |
The high silicon content gives A413 outstanding die-filling capability for the most intricate shapes.
Resists cracking during solidification, enabling large thin-wall sections.
Good atmospheric and general corrosion resistance for indoor and light-outdoor use.
A413 is normally die cast and used as-cast (F). It is not heat treated. Machining uses carbide tooling given the high silicon; painting and plating are common finishes. Anodizing is limited by silicon content.
Every A413 shipment is delivered with an MTC (material test certificate) covering chemical composition and mechanical properties as ordered. Dimensional inspection and third-party verification (e.g. SGS report, available on request) can be arranged. Our production system is managed under ISO 9001, ISO 14001, and ISO 45001.
Linsy operates a Shenzhen-based aluminum manufacturing facility with over 20 years of experience across the 1000–8000 series and a broad range of casting grades. We support both ingot supply and finished cast components with in-house CNC machining, polishing, and anodizing.
A413 has higher silicon (11–13% vs 7.5–9.5%) for better fluidity and thin-wall capability, but lower strength than A380. Choose A413 for intricacy, A380 for strength.
No. A413 is used as-cast (F) and gains its properties from composition and die-cast process alone.
For standard ingot and common sand/permanent-mold castings, typical lead time is 10–60 days depending on temper, quantity, and any required machining or surface finishing. Confirm exact timing with our sales team when requesting a quote.
Yes. Every shipment is supplied with an MTC (material test certificate / inspection report) covering chemical composition and mechanical properties as ordered.
We support custom dimensions, casting method selection, heat treatment (F, T4, T5, T6 as applicable), and downstream CNC machining, polishing, and anodizing. Share your drawing or spec and we will quote against it.
Our casting alloys are produced and inspected against widely recognized standards such as ASTM B26/B85 and EN 1706. Specific designation cross-references are listed on each product page; confirm the exact standard requirement for your market when ordering.
