Sold in a convenient syringe containing \u003cstrong\u003e10 DWT (1\/2 troy ounce)\u003c\/strong\u003e total weight, it is well suited for jewelers, metalsmiths, and fabricators working with copper, brass, bronze, and mixed-metal projects.\u003c\/p\u003e\u003cp\u003ePhos-copper paste solder flows at \u003cstrong\u003e1325°F\u003c\/strong\u003e — approximately the same temperature as a soft silver solder — making it accessible for a wide range of torch setups. The alloy produces a \u003cstrong\u003elight brassy color\u003c\/strong\u003e upon completion, blending naturally with brass and copper-toned metals. It has a long history of use in producing brass military belt buckles and similar fabricated brass components.\u003c\/p\u003e\u003cp\u003eThis paste is especially useful for mixed-metal work, including \u003cstrong\u003esilver to brass\u003c\/strong\u003e and \u003cstrong\u003estainless steel to brass or gold\u003c\/strong\u003e joints, expanding its versatility beyond single-metal projects.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eNote: The date printed on the syringe is the manufacturing date — it is not a sell-by or expiration date.\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCaution: Contains Fluorides.\u003c\/strong\u003e\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCadmium-free and indium-free formula\u003c\/li\u003e\n\u003cli\u003eFlows at 1325°F — comparable to soft silver solder\u003c\/li\u003e\n\u003cli\u003eProduces a light brassy color finish\u003c\/li\u003e\n\u003cli\u003eSuitable for copper, brass, bronze, and mixed-metal projects\u003c\/li\u003e\n\u003cli\u003eCompatible with silver-to-brass and stainless steel-to-brass or gold joints\u003c\/li\u003e\n\u003cli\u003eConvenient syringe format for controlled application\u003c\/li\u003e\n\u003cli\u003eFor hard (torch) soldering only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003ePhos-Copper Paste Solder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFlow Temperature\u003c\/th\u003e\n\u003ctd\u003e1325°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGrade\u003c\/th\u003e\n\u003ctd\u003eSoft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNet Weight\u003c\/th\u003e\n\u003ctd\u003e10 DWT (1\/2 troy oz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFormat\u003c\/th\u003e\n\u003ctd\u003eSyringe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCadmium Free\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIndium Free\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSoldering Method\u003c\/th\u003e\n\u003ctd\u003eHard (torch) soldering only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish Color\u003c\/th\u003e\n\u003ctd\u003eLight brassy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSafety Note\u003c\/th\u003e\n\u003ctd\u003eContains Fluorides\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":43585121714390,"sku":"154.840","price":5.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/copper-solder-paste-soft-12-oz-cadmium-free-otto-frei.jpg?v=1719955798","url":"https:\/\/www.ottofrei.com\/ja\/products\/phos-copper-solder-paste-soft-half-oz-cadmium-free","provider":"Otto Frei","version":"1.0","type":"link"}
