焊錫材料的主要成分其實是錫金屬和鉛金屬合金金屬，錫鉛合金的共晶點在183℃，一般為37%的鉛和63%錫xi，很hen多duo焊han錫xi材cai料liao大da部bu分fen都dou是shi以yi這zhe個ge比bi例li為wei主zhu的de。其qi實shi焊han錫xi是shi可ke以yi通tong過guo改gai變bian這zhe個ge錫xi鉛qian金jin屬shu的de比bi例li，來lai滿man足zu合he金jin熔rong點dian的de不bu同tong的de需xu求qiu。也ye可ke以yi在zai其qi中zhong添tian加jia多duo種zhong不bu同tong的de化hua學xue成cheng分fen，形xing成cheng不bu同tong的de焊han錫xi合he金jin。一yi般ban來lai說shuo含han鉛qian量liang的de焊han錫xi是shi適shi合he使shi用yong於yu焊han接jie溫wen度du高gao的de焊han接jie過guo程cheng的de。含han錫xi量liang高gao的de焊han錫xi則ze主zhu要yao被bei用yong於yu對dui防fang蝕shi要yao求qiu高gao的de焊han接jie過guo程cheng中zhong。
在焊錫的製作中其實是可以適當添加其他金屬元素的，以期能實現焊錫中想要達到的某種性質要求。比如在焊錫中添加少於2%deyinjinshu，jiukeyizengqiangzhegehanxicailiaodejixieqiangdu，danbusunhuaihanxidexingzhi，haikeyiranghanxizaiduyindebiaomianjinxingjieheshi，buhuiyinweiyinderongjieerjiangdihanxiderunshixing。zaihanxizhongtianjiajinshutongzeshiweilejianshaotongderongjiesudu，dadaoyanchangtonghanjiegongjudeshouming，danruguotonghanliangguodajiuhuizaochengxiaokuaizhuanghandian。muqianhanxixingyezhengzaidalifazhanhuanbaoxinghanxi，yejiushiwuqianhanxi，mudejiushibimianqianwuran，suoyihaikeyishidangdejianshaohanxizhongdehejinjinshu。
在zai焊han接jie過guo程cheng中zhong，熔rong化hua的de錫xi很hen容rong易yi就jiu會hui與yu其qi它ta金jin屬shu反fan應ying形xing成cheng金jin屬shu化hua合he物wu，若ruo這zhe樣yang的de化hua合he物wu脆cui性xing高gao，也ye會hui影ying響xiang焊han錫xi表biao麵mian的de張zhang力li和he潤run濕shi性xing，會hui嚴yan重zhong損sun壞huai焊han點dian的de質zhi量liang。所suo以yi焊han接jie時shi應ying該gai要yao盡jin可ke能neng降jiang低di接jie合he溫wen度du，縮suo短duan焊han接jie時shi間jian，盡jin力li避bi免mian產chan生sheng這zhe樣yang的de金jin屬shu化hua合he物wu。
