What Is 5457 Aluminum?<\/h2>\n

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.<\/p>\n

Available 5457 Aluminum Products<\/h2>\n

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<\/strong>. Le dimensioni seguenti sono intervalli tipici; altre misure possono essere discusse su richiesta.<\/p>\n

Lamiera e bobina<\/h3>\n

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.<\/p>\n

Piatto<\/h3>\n

Thick plate is not a standard 5457 product; thin rolled coil and sheet are the typical forms. Other gauges can be discussed on request.<\/p>\n

Barra (tonda, piatta, quadrata)<\/h3>\n

Barre tonde, piatte e quadrate possono essere prodotte con diametri o lunghezze laterali da 6 mm a 200 mm, normalmente in tempera O o H25.<\/p>\n

Tubo e condotto<\/h3>\n

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.<\/p>\n

Profilato estruso<\/h3>\n

Profili estrusi e trafilati per finiture sono disponibili su richiesta.<\/p>\n

Guida alla scelta della tempra<\/h2>\n

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.<\/p>\n

Caratteristiche principali<\/h2>\n

Bright anodizing<\/h3>\n

5457 was developed for a high-quality, reflective bright-anodized finish, its main reason for selection.<\/p>\n

Resistenza alla corrosione<\/h3>\n

Il comportamento alla corrosione \u00e8 buono per esposizione interna e architettonica.<\/p>\n

Formabilit\u00e0<\/h3>\n

In O and H25 tempers it forms and bends well for trim and cladding.<\/p>\n

La forza<\/h3>\n

Strength is moderate; it is chosen for appearance rather than load-bearing duty.<\/p>\n
