Primarily used for MIG, TIG, and oxyacetylene welding of copper, copper-silicon, and copper-zinc base metals to themselves and to steel. The oxyacetylene gas flame should be slightly oxidizing. Keep the weld puddle small in order to promote fast solidification and minimize cracking. A high boric acid flux should be used both before and during welding. Preheating is NOT recommended.\u003c\/span\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 0.030 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlloy Type:\u003c\/strong\u003e ERCuSi-A (RcuSi-A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Composition:\u003c\/strong\u003e Copper base, 3% Silicon, small % Manganese, Tin, Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilicon Content:\u003c\/strong\u003e 2.8-4.0%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManganese Content:\u003c\/strong\u003e Up to 1.50%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTin Content:\u003c\/strong\u003e Up to 1.00%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZinc Content:\u003c\/strong\u003e Up to 1.00%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Conductivity:\u003c\/strong\u003e 7.0% IACS (annealed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDensity:\u003c\/strong\u003e 0.308 lbs\/in3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Conductivity:\u003c\/strong\u003e 21 Btu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElongation:\u003c\/strong\u003e 65%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTensile Strength:\u003c\/strong\u003e 50,000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrinell Hardness:\u003c\/strong\u003e 80-100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e ANSI\/AWS A5.7, ASME SFA 5.7, AWS A5.27\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=\"Tech data sheet\" href=\"https:\/\/media.distributordatasolutions.com\/xlsx_washingtonalloy_v2\/2024q4\/documents\/a9f531e047fbaf3c76c67f7e95a90bfab2684d41.pdf\" target=\"_blank\"\u003eTech data sheet\u003c\/a\u003e\u003c\/address\u003e","brand":"Washington Alloy","offers":[{"title":"Default Title","offer_id":47733881569467,"sku":"WYTCU SB 04","price":0.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/wiscocatalog.myshopify.com\/products\/wytcu-sb-04-washington-alloy-tcu-sb-04-silicon-bronze-filler-metal-0030-in-ercusi-a-2-lb","provider":"Wisco Catalog","version":"1.0","type":"link"}
