With outstanding resistance to seawater corrosion, medium-to-high strength that persists at elevated temperatures (65\u2013170\u00b0C), and good weldability, 5454 aluminum is the preferred choice for pressure vessels, chemical storage tanks, marine pipelines, and automotive wheels where operating conditions exceed the comfort zone of standard alloys.<\/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 5454?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aluminium alloy 5454 belongs to the <strong>5xxx series<\/strong> of aluminum alloys, where <strong>magnesium (2.4\u20133.0%)<\/strong> serves as the primary alloying element, with <strong>manganese (0.5\u20131.0%)<\/strong> as a secondary strengthener.

While most aluminum alloys experience significant strength loss above 65\u00b0C, 5454 maintains good mechanical properties all the way up to <strong>170\u00b0C<\/strong>, making it the go-to alloy for applications involving heat, pressure, and corrosive environments simultaneously.<\/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\">2.68\u20132.69 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\">645 \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\">130\u2013135 W\/m\u00b7K<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">Electrical Resistivity<\/td><td class=\"has-text-align-center\" data-align=\"center\">34% IACS<\/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\u201370.5 GPa<\/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 5454<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aluminium 5454 derives its distinctive properties from a carefully balanced composition that sets it apart from other 5xxx series alloys.
