What Is 5059 Aluminum?<\/h2>\n

5059 aluminum is a high-magnesium 5xxx-series alloy developed for marine and structural applications that require the highest levels of corrosion resistance combined with strength. It carries approximately 5.0-6.0% magnesium, supported by manganese, chromium, and a deliberate zirconium addition that refines the grain structure and improves strength after welding. Because it is non-heat-treatable, 5059 is strengthened by strain hardening and is most often supplied in H116, H321, and H131 tempers for plate, sheet, and extrusions.<\/p>\n

In practice 5059 is treated as a stronger, more corrosion-resistant successor to 5083. It is widely specified for naval vessels, LNG and chemical tankers, offshore platforms, and large welded storage tanks where long service life in seawater is mandatory.<\/p>\n

    Exceptional Seawater Corrosion Resistance<\/h3>\n

    5059 offers the best exfoliation and stress-corrosion resistance among the high-Mg 5xxx alloys, especially in the H116\/H321 tempers after welding.<\/p>\n

    High Strength Without Heat Treatment<\/h3>\n

    Strain-hardened 5059 reaches tensile strengths near 400-440 MPa, rivalling some 6xxx and 7xxx tempers while remaining weldable.<\/p>\n

    \u51fa\u8272\u7684\u710a\u63a5\u6027<\/h3>\n

    5059 welds well with MIG and TIG processes. Use matching or 5xxx filler such as 5556 or 5183 to keep corrosion resistance in the heat-affected zone.<\/p>\n

    Good Low-Temperature Toughness<\/h3>\n

    Strength and toughness are retained at sub-zero temperatures, supporting LNG and cryogenic tank use.<\/p>\n

          5059 Aluminum FAQ<\/h2>\n

          Is 5059 the same as 5083?<\/h3>\n

          No. 5059 is a stronger, zirconium-modified variant of 5083 with higher allowable magnesium and better strength after welding. Choose 5059 where maximum corrosion resistance and strength are required.<\/p>\n

          Can 5059 be anodized?<\/h3>\n

          5xxx alloys anodise to a grey, sometimes uneven finish, so anodizing is not usually recommended for appearance. Powder coating or PVC film protection is preferred.<\/p>\n

          What filler should I use to weld 5059?<\/h3>\n

          Use a matching or higher-Mg 5xxx filler such as 5556 or 5183 to maintain corrosion resistance in the weld zone. Confirm the exact filler with your welding procedure.<\/p>\n

          Which tempers are available?<\/h3>\n

          Common tempers are O, H111, H116, H321, and H131. H116 and H321 are the standard marine plate tempers.<\/p>\n

          5059 aluminum is a high-magnesium 5xxx-series alloy engineered for marine and structural service that demands the highest levels of seawater corrosion resistance and strength. With roughly 5.0-6.0% magnesium plus manganese, chromium, and a small zirconium addition, 5059 reaches tensile strengths comparable to many heat-treatable grades while staying fully weldable and non-heat-treatable. Linsy supplies 5059 sheet, plate, bar, tube, and profile in H116, H321, H131, and O tempers for naval, offshore, and pressure-vessel applications.<\/p>\n
