The presence of inclusions and gaseous hydrogen destroys the continuity of the metal. Due to the different elastic modulus and expansion coefficient between the inclusion and the metal matrix, the sharp corners of the inclusion phase are prone to stress concentration and become a source of fracture and corrosion in the material. Various defects are likely to occur during the processing and deformation of aluminum alloy materials. In order to improve the Aluminum Alloy Melt Purity, in addition to the smelting of aluminum melt and the purification of the static process, the aluminum alloy purification system outside the furnace is more important.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3865\" src=\"https:\/\/aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/Aluminum-Alloy-Melt-Purity.jpg\" alt=\"\u0646\u0642\u0627\u0621 \u0633\u0628\u0627\u0626\u0643 \u0627\u0644\u0623\u0644\u0648\u0645\u0646\u064a\u0648\u0645 \u0627\u0644\u0645\u0635\u0647\u0648\u0631\u0629\" width=\"500\" height=\"400\" srcset=\"https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/Aluminum-Alloy-Melt-Purity.jpg 500w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/Aluminum-Alloy-Melt-Purity-300x240.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_83 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">\u062c\u062f\u0648\u0644 \u0627\u0644\u0645\u062d\u062a\u0648\u064a\u0627\u062a<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">\u062a\u0628\u062f\u064a\u0644<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewbox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewbox=\"0 0 24 24\" version=\"1.2\" baseprofile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.aluminiumceramicfiber.com\/ar\/aluminum-alloy-melt-purity\/#Aluminum_Alloy_Melt_Purity_Classification\" >Aluminum Alloy Melt Purity Classification<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.aluminiumceramicfiber.com\/ar\/aluminum-alloy-melt-purity\/#Production_Control_of_Purity\" >Production Control of Purity<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Aluminum_Alloy_Melt_Purity_Classification\"><\/span>Aluminum Alloy Melt Purity Classification<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>According to the measured data of online hydrogen measurement and the slag measurement method, the purity of aluminum liquid is divided.<\/p>\n<p>First-class purity: the ultra-thin aluminum foil, can body materials and other products.
