Aluminum Extrusion Heat Profiles Sink Sometimes aluminum extrusions need to be joined to form complex shapes or extended lengths. But is welding them really reliable, or will it compromise their strength? Yes, aluminum extrusions can be reliably welded using the right methods, materials, and post-processing. Weld quality depends on alloy type, surface prep, and proper […]<\/p>\n","protected":false},"author":6,"featured_media":7937,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","footnotes":""},"categories":[1],"tags":[],"class_list":["post-27427","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-custom-mold"],"meta_box":{"post-to-quiz_to":[]},"_links":{"self":[{"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/posts\/27427","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/comments?post=27427"}],"version-history":[{"count":0,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/posts\/27427\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/media\/7937"}],"wp:attachment":[{"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/media?parent=27427"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/categories?post=27427"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sinoextrud.com\/cs\/wp-json\/wp\/v2\/tags?post=27427"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
