It is a low melting temperature alloy that is very fluid and fast flowing. Best for tight fitting connections under two inches in diameter. Ideal for copper-to-brass applications such as solenoid valves, ball valves, Schrader valves and distributors. BLOCKADE® is self-fluxing on copper. Its lower melting temperature makes it an excellent choice for brass. Complies with the EU Reach \u0026amp; RoHS directive.\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\u003eA low cost alternative to silver bearing filler metals\u003c\/li\u003e\n\u003cli\u003eDoes not contain silver, so significant cost reductions are available\u003c\/li\u003e\n\u003cli\u003eFor brazing copper or brass, as the lower brazing temperature makes it an excellent replacement for many silver-bearing BCuP alloys\u003c\/li\u003e\n\u003cli\u003eNot recommended for brazing steel or other ferrous alloys\u003c\/li\u003e\n\u003cli\u003eIt has a narrow melting range, but its flow characteristics allow operators to “cap” or \"build-up\" around the finished joint\u003c\/li\u003e\n\u003cli\u003ePhosphorus containing brazing alloys should not be used if the braze is exposed to sulfur or sulfur compounds in service\u003c\/li\u003e\n\u003cli\u003eOften selected to replace silver brazing filler metals for these applications\u003c\/li\u003e\n\u003cli\u003eComplies with the EU Reach \u0026amp; RoHS directive\u003c\/li\u003e\n\u003cli\u003ePhosphorus content will form low ductility intermetallic with base metal\u003c\/li\u003e\n\u003cli\u003eLow melting point reduces the likelihood of overheating the brass\u003c\/li\u003e\n\u003c\/ul\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.03 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolidus Temperature:\u003c\/strong\u003e 1178 F (637 C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquidus Temperature:\u003c\/strong\u003e 1247 F (674 C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrazing Range:\u003c\/strong\u003e 1200 F - 1280 F (649 C - 693 C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Composition:\u003c\/strong\u003e Phosphorus 6.0-7.0%, Tin 6.0-7.0%, Silicon 0.01-0.40%, Copper remainder, Others 0.15%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDensity:\u003c\/strong\u003e 0.293 lbs.\/cu.in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e AWS A5.8 BCuP-9, ASME SFA 5.8 BCuP-9, ISO 17672 CuP 385, REACH, RoHS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable Base Materials:\u003c\/strong\u003e Copper, Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnsuitable Base Materials:\u003c\/strong\u003e Steel, Ferrous Alloys\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\/1153\/auto_mfr_template\/f6bcd5370cfd61dfe8f2075074a6fd843bbf505c.pdf\" target=\"_blank\"\u003eSpec Sheet\u003c\/a\u003e\u003c\/address\u003e","brand":"Harris Products Group","offers":[{"title":"Default Title","offer_id":47736462147771,"sku":"HSBK220R","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0705\/5763\/0651\/files\/04555f6acf227e267fb923c5e5aca6dbc71085f4-large.png?v=1778694092","url":"https:\/\/wiscocatalog.myshopify.com\/products\/hsbk220r-harris-products-group-bk220r-brazing-alloy-phos-copper-low-melting-point-self-fluxing-copper-to-brass","provider":"Wisco Catalog","version":"1.0","type":"link"}
