Coils","description":"\u003cp\u003eChoose from 4 different temperature flow points of silver wire solder, ideal for hard (torch) soldering — also known as brazing — on silver jewelry and metalwork. Each coil weighs approximately 1\/4 ounce (5 DWT), measures approximately 4-1\/2 feet in length, and is formed from round wire with a diameter of 0.032\" (0.8mm), equivalent to 20 gauge. Coils are sold individually.\u003c\/p\u003e\u003cp\u003eThe designations \u003cstrong\u003eExtra Easy\u003c\/strong\u003e, \u003cstrong\u003eEasy\u003c\/strong\u003e, \u003cstrong\u003eMedium\u003c\/strong\u003e, and \u003cstrong\u003eHard\u003c\/strong\u003e describe the relative temperature flow points within this solder family. Extra Easy flows at the lowest temperature, progressing upward through Easy and Medium to Hard at the highest. Generally, higher flow point temperatures correspond to higher silver content, which can improve color match to silver and theoretically produce a stronger bond. Note that flow point designations are relative within a brand—one maker's Medium may flow at the same temperature as another maker's Hard.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich grade should you use?\u003c\/strong\u003e When manufacturing, use the highest temperature (Hard) solder available so that subsequent repairs can be made with lower-temperature solders. When making repairs, use the lowest temperature (Extra Easy) solder possible, since the grade used previously is typically unknown.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAvailable in four flow point grades: Extra Easy, Easy, Medium, and Hard\u003c\/li\u003e\n\u003cli\u003eRound wire form — 0.032\" (0.8mm) diameter, 20 gauge\u003c\/li\u003e\n\u003cli\u003eEach coil approximately 1\/4 oz (5 DWT) and 4-1\/2 feet long\u003c\/li\u003e\n\u003cli\u003eFor use with hard (torch) soldering \/ brazing only\u003c\/li\u003e\n\u003cli\u003eHigher silver content grades offer closer color match to silver\u003c\/li\u003e\n\u003cli\u003eGraduated flow points allow sequential soldering of multiple joints\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eWire Diameter\u003c\/th\u003e\n\u003ctd\u003e0.032\" (0.8mm), 20 gauge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWire Form\u003c\/th\u003e\n\u003ctd\u003eRound wire\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCoil Weight\u003c\/th\u003e\n\u003ctd\u003eApproximately 1\/4 oz (5 DWT)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCoil Length\u003c\/th\u003e\n\u003ctd\u003eApproximately 4-1\/2 feet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSoldering Method\u003c\/th\u003e\n\u003ctd\u003eHard (torch) soldering \/ brazing only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSold As\u003c\/th\u003e\n\u003ctd\u003eIndividual coils\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eGrade\u003c\/th\u003e\n\u003cth\u003eFlow Point\u003c\/th\u003e\n\u003cth\u003eSilver Content\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e804-400\u003c\/td\u003e\n\u003ctd\u003eExtra Easy\u003c\/td\u003e\n\u003ctd\u003e1300°F \/ 705°C\u003c\/td\u003e\n\u003ctd\u003e56% Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e804-401\u003c\/td\u003e\n\u003ctd\u003eEasy\u003c\/td\u003e\n\u003ctd\u003e1325°F \/ 719°C\u003c\/td\u003e\n\u003ctd\u003e65% Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e804-402\u003c\/td\u003e\n\u003ctd\u003eMedium\u003c\/td\u003e\n\u003ctd\u003e1390°F \/ 755°C\u003c\/td\u003e\n\u003ctd\u003e70% Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e804-403\u003c\/td\u003e\n\u003ctd\u003eHard\u003c\/td\u003e\n\u003ctd\u003e1475°F \/ 802°C\u003c\/td\u003e\n\u003ctd\u003e75% Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Otto Frei","offers":[{"title":"Extra Easy","offer_id":43587031990486,"sku":"804-400","price":29.8,"currency_code":"USD","in_stock":false},{"title":"Easy","offer_id":47562358915286,"sku":"804-401","price":29.88,"currency_code":"USD","in_stock":true},{"title":"Medium","offer_id":47561579921622,"sku":"804-402","price":31.96,"currency_code":"USD","in_stock":true},{"title":"Hard","offer_id":47557498863830,"sku":"804-403","price":34.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/silver-wire-solders-extra-easy-easy-med-and-hard-14-oz-coils-otto-frei.jpg?v=1719955722","url":"https:\/\/www.ottofrei.com\/products\/silver-wire-solder-extra-easy-easy-medium-hard-quarter-oz-coils","provider":"Otto Frei","version":"1.0","type":"link"}
