5754 铝合金

What Is 5754 Aluminum?

5754 aluminum belongs to the 5xxx family of aluminum-magnesium alloys. With about 2.6-3.6% magnesium and small additions of manganese and chromium, it offers a strong balance of corrosion resistance, weldability, and formability. It is not strengthened by heat treatment; its properties come from strain hardening (the H tempers).

Because 5754 keeps good strength and ductility after welding and resists attack from seawater and many industrial chemicals, it is widely used in shipbuilding, vehicle bodies, and welded structures.

硬度选择指南

O / H111 give the best formability and the highest retained strength after welding – choose these for welded tanks, hulls, and deep-drawn parts.

H22 / H24 / H32 / H34 add moderate strength while staying formable, suiting vehicle body panels and structural components that are lightly formed.

H36 / H38 deliver the highest strength of the range for stiffeners and parts with little further forming.

主要特点

耐腐蚀性

5754 resists seawater and many industrial atmospheres better than most heat-treatable grades, which makes it a default choice for marine service.

焊接性

It welds readily by MIG and TIG using 5356 or 5183 filler. Strength in the weld zone stays close to the parent metal, so welded assemblies keep their integrity.

成型性

In O and soft H tempers it bends and draws well, supporting complex fabricated shapes.

Low-temperature behaviour

Toughness is maintained at low temperatures, useful for refrigerated and cryogenic-adjacent equipment.

应用

• Ship hulls, decks, and superstructures
• Welded pressure vessels and storage tanks
• Automotive and truck body panels
• Trailer and container structures
• 建筑与装饰面板
• Railway vehicle interiors

加工与表面处理说明

5754 is welded with MIG/TIG using 5356 or 5183 filler wire. It is not heat-treatable, so fabrication relies on cold work and welding rather than aging. The alloy cuts, saws, and bends cleanly; anodizing gives a uniform decorative finish when required.

5754 Aluminum FAQ

Is 5754 heat-treatable?

No. 5754 is a non-heat-treatable 5xxx alloy; its strength comes from magnesium content and strain hardening (O, H tempers).

What filler should I use for welding 5754?

5356 or 5183 filler is typical, matching the magnesium-rich base metal and preserving corrosion resistance in the joint.

5754 vs 5083 – which to pick?

5083 has higher magnesium (4.0-4.9%) and greater as-welded strength for heavy marine structures, while 5754 offers better formability for thinner, formed body and panel work.
