With a nominal magnesium content of approximately <strong>0.8%<\/strong>, Aluminium 5005 offers a balanced combination of properties that make it one of the most commonly used aluminum alloys in sheet and plate form.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Key Characteristics at a Glance:<\/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<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\">2.70 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\">632 \u2013 655 \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\">201 \u2013 205 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\">52% 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\">69.5 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 5005<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As a lean aluminum-magnesium alloy, 5005 aluminum derives its distinctive properties from a carefully balanced composition.
