Les aimants annulaires en n\u00e9odyme BMAG repr\u00e9sentent la r\u00e9f\u00e9rence en mati\u00e8re de densit\u00e9 de flux \u00e9lev\u00e9e pour les g\u00e9om\u00e9tries circulaires. Fritt\u00e9s \u00e0 partir d'un alliage haute performance de n\u00e9odyme, de fer et de bore, ces aimants offrent un BHmax (produit \u00e9nerg\u00e9tique maximal) extraordinaire dans un facteur de forme compact \u00e0 centre creux. La g\u00e9om\u00e9trie de l'anneau est sp\u00e9cialement con\u00e7ue pour permettre un passage m\u00e9canique ou un montage dans l'axe central, fournissant un champ magn\u00e9tique \u00e9quilibr\u00e9 qui rayonne sym\u00e9triquement autour du vide central.<\/p>\n

Ces aimants sont fabriqu\u00e9s gr\u00e2ce \u00e0 un processus rigoureux de m\u00e9tallurgie des poudres, garantissant un alignement uniforme des grains pour une anisotropie magn\u00e9tique maximale. Disponibles dans des grades allant de N33 \u00e0 N55, ils offrent une r\u00e9manence (Br) et une force coercitive (Hcj) exceptionnelles. Pour contrer les tendances naturelles \u00e0 l'oxydation des mat\u00e9riaux de terres rares, chaque anneau est prot\u00e9g\u00e9 par un rev\u00eatement triple couche de haute qualit\u00e9 Ni-Cu-Ni (Nickel-Cuivre-Nickel). Cela cr\u00e9e une finition r\u00e9sistante, brillante comme de l'argent, qui r\u00e9siste \u00e0 l'humidit\u00e9 et \u00e0 l'usure physique. Chaque pi\u00e8ce est rectifi\u00e9e avec pr\u00e9cision pour r\u00e9pondre \u00e0 des tol\u00e9rances dimensionnelles strictes, assurant un ajustement parfait pour les assemblages n\u00e9cessitant des forces de couple \u00e9lev\u00e9es ou des forces de maintien \u00e9lev\u00e9es.<\/p>\n

BMAG Neodymium Ring Magnets represent the gold standard in high-flux density for circular geometries. Sintered from a high-performance alloy of Neodymium, Iron, and Boron, these magnets deliver an extraordinary BHmax (Maximum Energy Product) in a compact, hollow-center form factor. The ring geometry is specifically engineered to allow for mechanical passage or center-axis mounting, providing a […]<\/p>\n","protected":false},"featured_media":3620,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[36,15,105,111,123],"product_tag":[],"class_list":["post-3619","product","type-product","status-publish","has-post-thumbnail","product_cat-by-coating","product_cat-by-shape","product_cat-neodymium-ring-magnets","product_cat-nickel-plated","product_cat-speaker","desktop-align-left","tablet-align-left","mobile-align-left","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product\/3619","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/comments?post=3619"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/media\/3620"}],"wp:attachment":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/media?parent=3619"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_brand?post=3619"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_cat?post=3619"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_tag?post=3619"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
