It is formulated to provide smooth flux application, even coverage, and excellent protection during brazing. The addition of boron extends the active life of the flux enabling it to withstand longer heating cycles. This makes it an ideal choice for induction brazing where intense localized heating is a factor, or heavy parts that often require longer heating time. Stay-Silv black flux is recommended for brazing copper and copper alloys, (except aluminum bronze), steel, and other ferrous base metals. Stay It is often used in brazing stainless steel, nickel alloys, and tungsten carbide. Stay-Silv black flux is used with many high silver brazing filler metals of the AWS A5.8 BAg classifications and ISO 17672 class Ag alloys. It is also suitable for use with many phosphorus-copper-silver alloys, (AWS BCuP and ISO CuP), for brazing copper to brass. Black flux turns clear, (transparent), close to brazing application temperature. This is a useful indicator in timing braze wire application.\u003c\/span\u003e\u003c\/p\u003e\u003cp id=\"usesTitle\" class=\"pdp-specs__title\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTurns clear close to brazing application temperature indicating prime braze wire application\u003c\/li\u003e\n\u003cli\u003eCan also be used with many phosphorus-copper-silver alloys\u003c\/li\u003e\n\u003cli\u003eHigh-temperature, all-purpose black flux for silver brazing\u003c\/li\u003e\n\u003cli\u003eConforms to the EU RoHS directive\u003c\/li\u003e\n\u003cli\u003eFormulated for applications where the work is subjected to rapid, localized heating.\u003c\/li\u003e\n\u003cli\u003eRecommended for brazing copper, copper alloys (except aluminum bronze), steel, stainless steel, nickel alloys, tungsten carbide and other ferrous base metals\u003c\/li\u003e\n\u003cli\u003eUse with stainless steel, carbide, heavy parts, prolonged heating cycles.\u003c\/li\u003e\n\u003cli\u003eProvides smooth flux application,even coverage and excellent protection during brazing\u003c\/li\u003e\n\u003cli\u003eActivity range of 1050°F-1700°F (566°C-925°C)\u003c\/li\u003e\n\u003cli\u003eIdeal for applications where large amounts of refractory oxides may form\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp id=\"usesTitle\" class=\"pdp-specs__title\"\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStainless steel\u003c\/li\u003e\n\u003cli\u003eCarbides\u003c\/li\u003e\n\u003cli\u003eSilver brazing\u003c\/li\u003e\n\u003cli\u003eHeavy parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive Temperature Range:\u003c\/strong\u003e 1050 F-1700 F (566 C-925 C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 1 lb.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Paste flux\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical Composition:\u003c\/strong\u003e Water 15-25%; Potassium Borates 50-75%; Potassium Fluorides 10-20%; Boric Acid 1-3%; Boron 1-3%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClassification:\u003c\/strong\u003e AWS A5.31 FB3 C; AMS 3411; Federal Spec O-F-499 Type B; EN 1045 Type FH12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoHS Compliant:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e US\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in USA:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1 Year\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShelf Life:\u003c\/strong\u003e 2 years from date of manufacture\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp id=\"usesTitle\" class=\"pdp-specs__title\"\u003e\u003cstrong\u003eDownloads\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003c\/ul\u003e\u003caddress\u003e\u003ca class=\"Spec Sheet\" href=\"https:\/\/media.distributordatasolutions.com\/xlsx_harris_products_group\/2021q1\/documents\/4dd53e42262a95d2485488c3d7d0a0d0c2f5f389.pdf\" target=\"_blank\"\u003eSpec Sheet\u003c\/a\u003e\u003c\/address\u003e\u003caddress\u003e\u003ca class=\"Guide\" href=\"https:\/\/media.distributordatasolutions.com\/xlsx_harris_products_group\/2021q1\/documents\/1eb7679e1fe39aee1b056d4374d5c399e7de56e9.pdf\" target=\"_blank\"\u003eGuide\u003c\/a\u003e\u003c\/address\u003e","brand":"Harris Products Group","offers":[{"title":"Default Title","offer_id":47736415125691,"sku":"HSSSBF1","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0705\/5763\/0651\/files\/562af710bf2ffcb4b5ae7dc7087f3531e330ca0d-large.png?v=1778685323","url":"https:\/\/wiscocatalog.myshopify.com\/products\/hsssbf1-harris-products-group-ssbf1-brazing-flux-paste-black-1-lb-1050f-1700f-566c-925c","provider":"Wisco Catalog","version":"1.0","type":"link"}
