protective oxide layer (Al\u2082O\u2083) when in contact with oxygen, this layer can break down under certain conditions, leading to corrosion. The most common forms of corrosion in aluminum include: <\/p><ul><li>Pitting: Occurs when exposed to chlorides (salt water), where the oxide layer breaks down locally, which can lead to deep perforations.<\/li><li>Galvanic corrosion: Occurs when aluminum is in contact with more noble metals such as copper or stainless steel in a humid or electrolytic environment.<\/li><li>Crevice corrosion: Occurs in narrow cracks or joints where oxygen access is limited, creating aggressive local environments.<\/li><li>Filiform corrosion: Occurs under paint and coating systems if moisture penetrates and breaks down the adhesion.<\/li><li>Intercrystalline corrosion: Can occur in certain aluminum alloys, where corrosion attack occurs along the grain boundaries in the material.<\/li><\/ul><p>To minimize these corrosion risks, a combination of surface treatment, appropriate coating systems and cathodic protection is used.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1f6db8c5 cta elementor-widget elementor-widget-button\" data-id=\"1f6db8c5\"

Surface preparation<\/strong><\/p><p>To ensure optimal corrosion protection and adhesion of protective coatings, thorough pre-treatment of the aluminum surface is required:<\/p><ul><li>Alkaline or acid-based cleaning: Removes oxides, grease and impurities.<\/li><li>Anodizing: An electrolytic process that artificially reinforces the natural oxide layer and creates a hard, corrosion-resistant surface.<\/li><li>Chromating or zirconium treatment: Chemical pre-treatments that improve the adhesion of paints and coatings and increase corrosion resistance.<\/li><\/ul><p><strong>2. Protective coating systems<\/strong><\/p><p>Despite the natural oxide layer, aluminum requires an additional protective coating in many applications to resist aggressive environmental influences:<\/p><ul><li>Epoxy and polyurethane coatings: High mechanical and chemical resistance, ideal for industrial and marine environments.<\/li><li>Fusion Bonded Epoxy coating, particularly strong coating against aggressive environments.<\/li><li>Powder coated coatings: Often used on aluminum facades and components to improve corrosion resistance and aesthetics.<\/li><li>Zinc or zirconium-containing primers: Create a barrier against galvanic corrosion when aluminum is in contact with other metals.<\/li><\/ul><p><strong>3. Cathodic protection of aluminum<\/strong><\/p><p>In certain extreme environments, such as offshore installations and marine applications, cathodic protection can be used to prevent corrosion:<\/p><ul><li>Sacrificial anodes (galvanic protection): Magnesium or zinc anodes can be used to protect aluminum, but must be chosen carefully to avoid unwanted electrochemical reactions.<\/li><li>Impressed current systems (ICCP): Can be used in certain underwater applications to control corrosion potential.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3d74fceb cta elementor-mobile-align-justify elementor-widget-mobile__width-inherit elementor-widget elementor-widget-button\" data-id=\"3d74fceb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/jakob-albertsen.dk\/en\/contact\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Contact us<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-610891af e-flex e-con-boxed e-con e-parent\" data-id=\"610891af\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-6fd7d27a e-con-full e-flex elementor-invisible e-con e-child\" data-id=\"6fd7d27a\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;animation&quot;:&quot;fadeInLeft&quot;}\">\n\t\t<div class=\"elementor-element elementor-element-17878a7a e-con-full e-flex e-con e-child\" data-id=\"17878a7a\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-507f755d prehead elementor-widget elementor-widget-text-editor\" data-id=\"507f755d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>JAKOB ALBERTSEN KOMPOSIT A\/S<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6c2e2ce elementor-widget elementor-widget-text-editor\" data-id=\"6c2e2ce\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>Corrosion protection of aluminum according to ISO standards<\/h2><p>Several international standards regulate corrosion protection of aluminum, including:<\/p><ul><li>ISO 12944: Used primarily for steel structures, but can also guide the selection of coating systems for aluminum in aggressive environments.<\/li><li>ISO 7599: Standard for anodized aluminum products, specifying requirements for the thickness and quality of the oxide layer.<\/li><li>ISO 9227: Salt spray test used to evaluate the corrosion resistance of aluminum surfaces.<\/li><\/ul><h3>Advanced corrosion protection for aluminum from Jakob Albertsen Komposit A\/S<\/h3><p>At Jakob Albertsen Komposit A\/S we offer tailor-made solutions for corrosion protection of aluminum, whether it concerns industry, offshore or building constructions.
