產(chǎn)品詳情
云南省斯米克銀焊條焊絲銷售價(jià)格 銀基釬料是一種以銀或銀基固溶體的釬料。具有優(yōu)良的工藝性能,不高的熔點(diǎn),良好的濕潤(rùn)性和填滿間隙的能力,并且強(qiáng)度高。塑性好,導(dǎo)電性和耐蝕性優(yōu)良,可以用來釬焊所有黑色和有色金屬,如不銹鋼,硬質(zhì)合金、金剛石等各種材料。廣泛應(yīng)用于制冷、燈飾、五金電器、儀器儀表、化工、航空航天等工業(yè)制造領(lǐng)域。
為了降低熔點(diǎn)及減少銀含量,加入銅、鋅、鎘、錫、鎳等構(gòu)成三元或多元合金釬料。銀釬料適用于各種釬焊方法,但除在真空或保護(hù)氣氛中釬焊以外,一般需要配合銀釬劑共同使用,方可獲得優(yōu)良的釬縫。
銀基釬料按其成分構(gòu)成可分為無鎘釬料和含鎘釬料。含鎘釬料具有一定的毒性,不適宜用于與食物、飲用水直接接觸接頭的釬焊。釬焊工作點(diǎn)需通風(fēng)。
釬焊前必須嚴(yán)格清除釬焊處及釬料表面的油脂,氧化物等,釬焊接頭的最佳間隙為0.03mm~0.075mm。
