5657 aluminum is a non-heat-treatable 5xxx alloy with about 1 percent magnesium, known for its excellent anodizing characteristics. It combines good corrosion resistance with moderate strength and is particularly popular where surface finish and aesthetic appeal are important, such as architectural trim, building facades, and consumer product casings.

5657 is a non-heat-treatable 5xxx alloy with about 1 percent magnesium, developed for high-quality anodized surfaces. It provides an excellent anodizing response, good corrosion resistance, and moderate strength, and is widely used for decorative and architectural finishes.
Linsy supplies 5657 mainly as sheet and coil for anodized decorative finishes, with bar and profiles available on request. The tempers most commonly supplied are O, H25, H28, and H38. Dimensions below are typical ranges; other sizes can be discussed on request.
5657 is supplied primarily as thin-gauge sheet and coil in thicknesses from 0.3 mm to 4 mm, widths up to 2000 mm, and lengths up to 6000 mm or cut to size.
Thick plate is not a standard 5657 product; thin rolled coil and sheet are the typical forms. Other gauges can be discussed on request.
Round, flat, and square bars can be produced in diameters or side lengths from 6 mm to 200 mm, normally in O or H25.
5657 tube can be supplied in outer diameters from 6 mm to 200 mm with wall thicknesses from 0.5 mm to 20 mm, usually in O or H25 temper.
Extruded and drawn profiles for trim are available on request.
5657 is identified by the following common standards and designations.
| Стандарт | Наименование |
|---|---|
| AA | 5657 |
| UNS | A95657 |
| EN AW | EN AW-AlMg1 |
The typical composition of 5657 aluminum is listed below in weight percent, with aluminum as the balance.
| Элемент | Состав (%) |
|---|---|
| Кремний (Si) | 0,25 макс. |
| Железо (Fe) | 0.40 max |
| Медь (Cu) | 0.10 макс. |
| Марганец (Mn) | 0.15 – 0.35 |
| Магний (Mg) | 0,8 – 1,2 |
| Хром (Cr) | 0,05 макс. |
| Цинк (Zn) | 0.10 макс. |
| Титан (Ti) | 0.03 max |
| Others each | 0.05 |
| Others total | 0.15 |
| Алюминий (Al) | Баланс |
The values below are typical for rolled and extruded products and should be confirmed against the mill test certificate for the specific temper and thickness ordered.
| Темпер | Прочность на разрыв (МПа) | Предел текучести (МПа) | Удлинение (%) |
|---|---|---|---|
| O | 115 – 160 | 45 min | 18 |
| H25 | 180 – 220 | 150 min | 8 |
| H28 | 215 – 260 | 180 min | 5 |
| H38 | 230 – 270 | 200 min | 4 |
Choose O or H25 for bright decorative trim that is formed before anodizing; H28 and H38 give higher strength for anodized parts that are not heavily formed.
5657 is valued for a clear, consistent, and attractive anodized finish, its main selection reason.
Corrosion behavior is good for interior and architectural exposure.
In O and H25 tempers it forms and bends well for panels and trim.
Strength is moderate; the grade is chosen for appearance more than load capacity.
5657 is most often supplied for anodizing and polishing; surface preparation before finishing is important. It can be cut, bent, and CNC machined. It is non-heat-treatable, so no solution heat treatment is involved.
Linsy provides a mill test certificate (MTC) with every shipment, documenting chemical composition and mechanical properties per EN 10204 3.1 where applicable. Third-party inspection and SGS material test reports can be arranged on request. Production is managed under ISO 9001 (quality), ISO 14001 (environment), and ISO 45001 (occupational health and safety) systems.
Linsy Aluminum operates a production and processing base with over 20 years of experience across the 1xxx to 8xxx aluminum series. For 5657, we supply sheet, plate, bar, tube, and extruded profiles with optional CNC machining, laser cutting, and surface finishing such as anodizing and polishing. Every order is shipped with a mill test certificate (MTC), and production follows ISO 9001, ISO 14001, and ISO 45001 management systems. Custom dimensions and tempers can be arranged, with typical lead times of 10 to 60 days depending on the specification.
Its low magnesium content and clean composition give a uniform, bright anodized surface that higher-magnesium grades cannot achieve.
No. It is a non-heat-treatable 5xxx alloy; tempers are O and H-strain-hardened only.
5005 is the most common anodizing grade; 5657 and 5457 are selected for brighter or formed decorative trim. Confirm the exact spec with our team.
Yes for architectural trim, though in aggressive marine environments a higher-magnesium grade may be preferred for corrosion reasons.
MOQs depend on form and temper. Standard stock items often start from a few hundred kilograms, while custom sizes are quoted per inquiry.
Standard specifications are usually available within 10 to 60 days. Custom tempers or dimensions may require longer; we confirm a date with each quotation.
A mill test certificate (MTC) is included with every order. Production carries ISO 9001, ISO 14001, and ISO 45001 system certifications, and SGS or third-party test reports can be supplied on request.
Yes. Linsy supports cut-to-size, custom dimensions, and selected tempers. Share your drawing or specification for a quote.
Products are packed to prevent surface damage in transit, with export-standard seaworthy packaging available.
