FUSiO2N<\/a>\u2122<\/a>\u00a0SP de Rex Materials est sp\u00e9cialement formul\u00e9 pour les copeaux utilis\u00e9s dans les machines de coul\u00e9e Wagstaff. FUSiO2N SP est une composition de silice fusionn\u00e9e de tr\u00e8s haute puret\u00e9, avec une granulom\u00e9trie extr\u00eamement fine, qui offre des propri\u00e9t\u00e9s d\u2019usure exceptionnelles ainsi qu\u2019une excellente r\u00e9sistance aux chocs thermiques. Des propri\u00e9t\u00e9s sp\u00e9ciales d\u2019immersion quasi nulle, ainsi qu\u2019une finition en nitrure de bore int\u00e9gr\u00e9e au usinage, emp\u00eachent l\u2019adh\u00e9rence du m\u00e9tal et l\u2019attaque par l\u2019aluminium et d\u2019autres m\u00e9taux fondu. FUSiO2N SP a pass\u00e9 toutes les principales tests de r\u00e9sistance \u00e0 l\u2019aluminium sp\u00e9cifi\u00e9s par les principaux fabricants d\u2019aluminium.<\/p>\n

La faible masse thermique et la faible conductivit\u00e9 minimisent le risque de blocages lors de l\u2019amor\u00e7age ou \u00e0 faible d\u00e9bit de m\u00e9tal. Notre proc\u00e9d\u00e9 sp\u00e9cial FUSiO2N SP nous permet d\u2019offrir cette performance exceptionnelle \u00e0 un prix tr\u00e8s raisonnable. Notre proc\u00e9d\u00e9 a \u00e9t\u00e9 con\u00e7u de mani\u00e8re \u00e0 ce que la surface de contact m\u00e9tallique de nos embouts soit pratiquement d\u00e9pourvue de porosit\u00e9s.<\/p>\n

Les tests effectu\u00e9s par le client montrent que le FUSiO2N SP dure plus longtemps que les pinces en silice fusionn\u00e9e traditionnelles. Nous sommes tellement convaincus que vous serez satisfait de la performance que nous offrons que nous proposons une garantie de remboursement !<\/p>\n
