With a magnesium content of 3.5\u20134.5%, 5086 aluminium offers an exceptional balance of seawater corrosion resistance, weldability, and moderate\u2011to\u2011high strength. It is the material of choice for boat and yacht hulls, vessel gangways, cryogenic tanks, offshore platforms, and any application where weld integrity and long\u2011term durability in saltwater are paramount \u2013 bridging the gap between the formability of 5052 and the extreme strength of 5083.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is Aluminium 5086?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aluminium alloy 5086 is a member of the <strong>5xxx series<\/strong> (aluminium\u2011magnesium), registered with the US Aluminium Association in <strong>1954<\/strong> as part of the post\u2011war expansion of marine\u2011grade alloys. Like 5052, 5754, 5454, and 5083, 5086 is a <strong>non\u2011heat treatable<\/strong> alloy; its strength comes from <strong>solid solution strengthening<\/strong> (magnesium dissolved in aluminium) and <strong>cold working (strain hardening)<\/strong>, not from heat treatment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Within the 5000 series, 5086 occupies a <strong>distinct middle ground<\/strong>. It is stronger than 5052 but not as strong as 5083; it is more weldable than 5083 in certain respects, particularly regarding <strong>stress\u2011corrosion cracking resistance at weld seams<\/strong>, while offering better formability than its higher\u2011strength cousin. This balanced profile \u2013 combined with the US Navy\u2019s adoption of 5086 sheet (H32) and extrusions (H111) in the 1960s \u2013 has made 5086 a <strong>mainstay of shipbuilding, offshore engineering, and cryogenic equipment<\/strong>.<\/p><div class=\"pai-ad\" style=\"min-height:250px;visibility:hidden;\"><span style=\"display: block; text-align: center; font-size: 10px; margin: 0 0 10px 0; color: #999999;\">Ads<\/span>\r\n<!-- Display-300x250-1 -->\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:inline-block;width:300px;height:250px\"\r\n     data-ad-client=\"ca-pub-3838168351244230\"\r\n     data-ad-slot=\"9933646018\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Key Characteristics at a Glance:<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-center\" data-align=\"center\">Property<\/th><th class=\"has-text-align-center\" data-align=\"center\">Value<\/th><\/tr><\/thead><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\">Density<\/td><td class=\"has-text-align-center\" data-align=\"center\">2.66 g\/cm\u00b3<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">Melting Range<\/td><td class=\"has-text-align-center\" data-align=\"center\">574 \u2013 590 \u00b0C<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">Thermal Conductivity<\/td><td class=\"has-text-align-center\" data-align=\"center\">125 \u2013 127 W\/m\u00b7K<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">Modulus of Elasticity<\/td><td class=\"has-text-align-center\" data-align=\"center\">70 \u2013 71 GPa<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">Electrical Resistivity<\/td><td class=\"has-text-align-center\" data-align=\"center\">29 \u2013 34% IACS<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Data compiled from industry specifications<\/em><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:75px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Chemical Composition of Aluminium 5086<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aluminium 5086 derives its balanced properties from a composition that sits between 5052 and 5083.
