5457 aluminum is a non-heat-treatable 5xxx alloy with low magnesium, specifically developed for bright-anodized decorative trim. It combines good strength, excellent corrosion resistance, and superior bright anodizing characteristics, making it well suited to automotive bright trim, architectural molding, and other applications where appearance and durability matter.

5457 is a non-heat-treatable 5xxx alloy with low magnesium (about 1 percent) and manganese, engineered for bright-anodized decorative trim. It offers good strength, excellent corrosion resistance, and a high-quality bright finish after anodizing, which makes it ideal for automotive and architectural trim.
Linsy supplies 5457 mainly as sheet and coil for bright trim, with bar, tube, and profiles available on request. The tempers most commonly supplied are O, H25, and H28. Las dimensiones a continuación son rangos típicos; otros tamaños pueden consultarse bajo solicitud.
5457 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. O and H25 are the common trim tempers.
Thick plate is not a standard 5457 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.
5457 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.
5457 is identified by the following common standards and designations.
| Estándar | Denominación |
|---|---|
| AA | 5457 |
| UNS | A95457 |
| EN AW | EN AW-AlMg1 |
The typical composition of 5457 aluminum is listed below in weight percent, with aluminum as the balance.
| Elemento | Composición (%) |
|---|---|
| Silicio (Si) | 0.08 max |
| Hierro (Fe) | 0,10 máx. |
| Cobre (Cu) | 0,10 máx. |
| Manganeso (Mn) | 0.10 – 0.40 |
| Magnesio (Mg) | 0,8 – 1,2 |
| Cromo (Cr) | 0.05 – 0.20 |
| Zinc (Zn) | 0,05 máx. |
| Titanio (Ti) | 0,05 máx. |
| Otros cada uno | 0.05 |
| Otros total | 0.15 |
| Aluminio (Al) | Saldo |
Los valores a continuación son típicos para productos laminados y extruidos y deben confirmarse con el certificado de prueba del molino para el temple y espesor específicos solicitados.
| Temple | Resistencia a la tracción (MPa) | Límite elástico (MPa) | Alargamiento (%) |
|---|---|---|---|
| O | 130 – 180 | 55 min | 18 |
| H25 | 200 – 240 | 170 min | 8 |
| H28 | 230 – 270 | 200 min | 5 |
Use O or H25 where the part must be formed before bright anodizing; H28 gives higher strength for decorative parts that are not heavily formed. 5457 is not heat-treatable, so no T tempers apply.
5457 was developed for a high-quality, reflective bright-anodized finish, its main reason for selection.
Corrosion behavior is good for interior and architectural exposure.
In O and H25 tempers it forms and bends well for trim and cladding.
Strength is moderate; it is chosen for appearance rather than load-bearing duty.
5457 is most often supplied for bright anodizing and polishing; surface cleanliness before finish is important. It can be cut, bent, and CNC machined. It is non-heat-treatable, so no solution heat treatment is involved.
Linsy proporciona un certificado de prueba del molino (MTC) con cada envío, documentando la composición química y las propiedades mecánicas según EN 10204 3.1 cuando corresponda. Se puede organizar una inspección por terceros e informes de prueba de materiales SGS bajo solicitud. La producción se gestiona bajo los sistemas ISO 9001 (calidad), ISO 14001 (medio ambiente) e ISO 45001 (salud y seguridad ocupacional).
Linsy Aluminum operates a production and processing base with over 20 years of experience across the 1xxx to 8xxx aluminum series. For 5457, 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.
No. 5457 is a non-heat-treatable 5xxx alloy; its properties come from strain hardening (O, H25, H28). The source often lists a solution-heat-treated temper in error, which does not apply to this grade.
Its low magnesium content allows a high-quality, reflective bright-anodized finish that higher-magnesium grades cannot match.
Both are low-magnesium bright-anodizing grades; 5657 is typically used for architectural anodized sheet while 5457 is favored for formed automotive trim. Confirm the exact spec with our team.
It can be welded, but for decorative trim mechanical joining or adhesive bonding is more common to preserve the finish.
Las cantidades mínimas de pedido (MOQ) dependen de la forma y el temple. Los artículos estándar en stock a menudo comienzan desde unos pocos cientos de kilogramos, mientras que los tamaños personalizados se cotizan por consulta.
Las especificaciones estándar suelen estar disponibles en un plazo de 10 a 60 días. Los temple o dimensiones personalizados pueden requerir más tiempo; confirmamos una fecha con cada cotización.
Se incluye un certificado de prueba de fábrica (MTC) con cada pedido. La producción cuenta con certificaciones de sistema ISO 9001, ISO 14001 e ISO 45001, y se pueden proporcionar informes de prueba de SGS o de terceros bajo solicitud.
