Linsy A383 is an aluminum-silicon-copper die casting alloy offering an excellent balance of high fluidity, superior pressure tightness, and good strength. It is preferred over A380 for intricate parts and those requiring improved hot-cracking resistance during casting. A383 achieves its properties in the as-cast (F) condition and performs reliably in high-pressure applications.

Linsy supplies A383 in the forms most useful for foundries and component buyers. Standard and custom dimensions are available; contact our team for non-listed sizes.
| Formulier | Typical Size / Specification | Common Use |
|---|---|---|
| Die casting | Per drawing; wall 0.8–6 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 | Benaming |
|---|---|
| Former / trade style | A383 |
| AA (Aluminum Association) | A383 |
| NL | 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 | 9.5–11.5 |
| Fe | 1.3 max |
| Cu | 2.0–3.0 |
| Mn | 0.50 max |
| Mg | 0,10 max |
| Zn | 1.0 max |
| Ni | 0.50 max |
| Anderen, elk | 0,05 max |
| Overige, totaal | 0,15 max |
| Al | Rest |
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 | Treksterkte (MPa) | Opbrengststerkte (MPa) | Rek (%) |
|---|---|---|---|
| F (as-cast) | 300–320 | 145–160 | 2.5–4.0 |
| T5 | 300–320 | 150–170 | 2.0–3.5 |
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. |
| T5 | Artificially aged only (no solution treatment). Improved strength with lower cost and distortion than T6. |
Higher silicon than A380 lets A383 fill very thin and complex die cavities with fewer cold-shut defects.
Improved resistance to hot tearing supports intricate geometries and large flat sections.
Fine, sound microstructure suits hydraulic and pneumatic housings.
A383 is normally die cast and used as-cast. Machining and surface finishing follow standard aluminum die-cast practice. Like A380, anodizing is limited by high silicon; painting or plating are the usual finishes.
Every A383 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.
Choose A383 for very intricate or thin-wall castings and where hot-cracking resistance is important. A380 remains the default for general strength-driven parts.
It is typically supplied as-cast (F). T5 may be applied for added stability but is less common than for A356/A357.
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.
