{"product_id":"master-alloy-for-casting-925-silver","title":"Legor® SF928CH - Casting Alloy 925 Silver","description":"\u003cp\u003eLegor's SF928CH is a master alloy for 925‰ silver jewelry, designed for lost-wax casting in closed and open systems. This formulation can be alloyed from title 925‰ to title 935‰. It is particularly suitable for stone-in-place casting. The hardness of 925‰ silver alloyed with SF928CH can be moderately increased by means of a heat treatment. Please refer to the technical chart for information on the correct age-hardening procedure. SF928CH has a medium level of deoxidizers; this makes it suitable for casting in open systems, although the alloy can be used with success also in closed systems. SF928CH offers excellent fluidity in casting; the as-cast tree is clean from oxide scales; it has extremely high shininess and lustrous color after finishing. \u003cstrong\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0251\/1947\/files\/sf928ch_msds.pdf?9095601647076998814\" target=\"_blank\" title=\"MSDS\"\u003eMSDS.\u003c\/a\u003e \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0251\/1947\/files\/sf928ch_tech_sheet.pdf?9095601647076998814\" target=\"_blank\" title=\"Tech Sheet\"\u003eTechnical Sheet.\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"Legor","offers":[{"title":"1 oz.","offer_id":4408085697,"sku":"SF928CH","price":7.75,"currency_code":"USD","in_stock":true},{"title":"16 oz.","offer_id":4408085761,"sku":"SF928CH","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0251\/1947\/products\/sf928ch_1.jpg?v=1738440206","url":"https:\/\/zikjewelrytools.com\/products\/master-alloy-for-casting-925-silver","provider":"DECOZE JEWELRY TOOLS","version":"1.0","type":"link"}
