It is non-heat-treatable, so its strength is developed through cold work and strain hardening rather than solution or precipitation treatment. The alloy contains approximately 4.5\u20135.6% magnesium and 0.05\u20130.20% chromium, giving it a combination of high strength, good weldability and outstanding resistance to marine and industrial atmospheres.<\/p>\n<p>5056 wire is most commonly used as a filler metal for welding magnesium-rich 5xxx alloys, and as cold-heading or rivet wire where strength and corrosion resistance are both required. It is supplied in <strong>O<\/strong> (annealed), <strong>H32<\/strong> (quarter-hard), <strong>H34<\/strong> (half-hard) and <strong>H111<\/strong> (lightly worked, annealed) tempers. Equivalent designations include UNS A95056, EN AW-5056 (AlMg5Cr), JIS A5056 and GB\/T 3190 5056.<\/p>\n<h2>Available 5056 Aluminum Products<\/h2>\n<h3>Filo di alluminio 5056<\/h3>\n<p>This page focuses on 5056 aluminum wire.

Use when the wire will be bent, headed, crimped or formed into complex shapes before going into service.<\/li>\n<li><strong>H32 \u2013 Quarter-hard:<\/strong> A good balance of strength and ductility. Suitable for general structural fasteners, rivets and lightly stressed brackets.<\/li>\n<li><strong>H34 \u2013 Half-hard:<\/strong> Higher strength with reduced but still useful ductility. Choose for pins, clips, springs and fasteners where higher load-carrying capacity is needed.<\/li>\n<li><strong>H111 \u2013 Lightly worked, annealed:<\/strong> Similar to O but with slightly better surface finish and dimensional consistency. Often used for decorative or precision wiring and for lightly formed parts.<\/li>\n<\/ul>\n<h2>Key Characteristics of 5056 Aluminum Wire<\/h2>\n<h3>High Strength for a Non-Heat-Treatable Alloy<\/h3>\n<p>The magnesium content of 5056 makes it one of the stronger 5xxx alloys in the cold-worked condition. H34 temper wire can reach tensile strengths above 400 MPa while remaining weldable and corrosion resistant.<\/p>\n<h3>Excellent Marine and Industrial Corrosion Resistance<\/h3>\n<p>The Mg-Cr combination forms a stable protective film, giving 5056 very good resistance to seawater, salt spray and humid industrial environments. This makes it a natural choice for marine fittings, coastal structures and offshore hardware.<\/p>\n<h3>Good Weldability as a Filler Metal<\/h3>\n<p>5056 is frequently used as a filler wire for gas-metal-arc (MIG) and gas-tungsten-arc (TIG) welding of 5083, 5086 and 5456 base alloys. The chemistry matches the base-metal Mg level closely, producing weld metal with compatible strength and corrosion behavior.<\/p>\n<h3>Work-Hardening, Not Heat-Treatable<\/h3>\n<p>Strength is controlled by cold drawing and annealing, not by heat treatment. This is an advantage for wire producers because properties are stable during shipping and storage, but it means users cannot increase strength by artificial aging.<\/p>\n<h3>Storage and Handling Cautions<\/h3>\n<p>High-magnesium aluminum alloys can be sensitive to stress-corrosion cracking if stored in warm, corrosive environments after heavy cold work. Store coils in a dry location and avoid contact with copper, steel or chloride salts.<\/p>\n<h2>Applicazioni comuni<\/h2>\n<ul>\n<li>Welding rods and filler wire for 5083, 5086 and 5456 alloys<\/li>\n<li>Marine components, railings, fasteners and rigging<\/li>\n<li>Pressure vessels and cryogenic tanks<\/li>\n<li>Structural fabrication in corrosive environments<\/li>\n<li>Rivets, pins, clips and cold-headed fasteners<\/li>\n<li>Electrical grounding and braided shielding (where conductivity is acceptable)<\/li>\n<\/ul>\n<h2>Note sulla lavorazione e sulla finitura superficiale<\/h2>\n<p>5056 wire is produced by cold drawing from redraw rod, followed by annealing (for O and H111) or controlled cold reduction (for H32 and H34). Straightening, cutting and surface cleaning can be performed as final operations. Linsy can supply the wire on DIN spools, random-wound coils or as precision-cut lengths.<\/p>\n<p>Surface finishes normally include <strong>mill finish<\/strong> with a light oxide film; optional cleaning, degreasing and PVC wrapping are available for applications requiring bright, contaminant-free wire before welding or anodizing. Because 5056 is often used as a welding filler, surface cleanliness is critical: avoid copper or steel contamination and keep the wire dry until use.<\/p>\n<h2>Documenti di qualit\u00e0 e ispezione<\/h2>\n<ul>\n<li><strong>Mill Test Certificate (MTC):<\/strong> Issued with every order, showing chemical analysis, mechanical test results and dimensional checks.<\/li>\n<li><strong>Third-party test reports:<\/strong> SGS reports and other independent inspections are available on request.<\/li>\n<li><strong>Management system certificates:<\/strong> Linsy operates under ISO 9001, ISO 14001 and ISO 45001.<\/li>\n<li><strong>Dimensional inspection:<\/strong> Diameter, ovality and coil weight are checked against the order specification.<\/li>\n<\/ul>\n<p>We do not claim blanket stock of every diameter or temper.

For 6061, 5356 or 4043 filler is normally preferred.<\/p>\n<p><strong>Which temper should I choose for rivets?<\/strong><br \/>O temper is easiest to drive and form; H32 is often used for structural rivets that must retain higher shear strength. The best choice depends on the rivet diameter and the required shear load.<\/p>\n<p><strong>Does 5056 wire need special storage?<\/strong><br \/>Store in a dry, covered area. High-magnesium alloys can be sensitive to stress corrosion if exposed to chloride or warm, humid conditions after heavy cold work. Keep the wire free of copper, steel or grease contamination.<\/p>\n<p><strong>Is a mill test certificate included?<\/strong><br \/>Yes.
