銀基釬料Silver base filler metals
使用說明 Operation Introduction
銀基釬料是一種以銀或銀基固熔體的釬料。具有優良的工藝性能，不高的熔點，良好的濕潤性和填滿間隙的能力，并且強度高，塑性好，導電性和耐蝕性優良，可以用來釬焊所有黑色和有色金屬，如不銹鋼，硬質合金、金鋼石等各種材料。廣泛應用于制冷、燈飾、五金電器、儀器儀表、化工、航空航天等工業制造領域。
為了降低熔點及減少銀含量，加入銅、鋅、鎘、鎳、錫等構成三元或多元合金釬料。銀釬料適用于各種釬焊方法，但除在真空或保護氣氛中釬焊以外，一般要配合銀釬劑共同使用，方可獲得優良的釬縫。
銀基釬料按其成分構成可分為無鎘釬料和含鎘釬料。含鎘釬料具有一定的毒性，不適宜用于食物，飲用水直接接觸接頭的釬焊。釬焊工作點需通風。
The silver-base filler metals are a kind of brazing filler metals of silver-base solid solution,with excellent usability,low melting point,good wettability,great strength,good plasticity,contact and corrosion-resisting.They can be used to brazed all ferrous and nonferrous metals ,such as stainless steel,hard alloy etc.At present,they are applied on the fields such as refrigerator,air conditioner,lamps and lantems,instruments and meters,electrical equipments chemical industry and aerospace industry etc.
In order to decrease melting point and the content of silver,adding copper,zinc,admium,tin,nickel etc elements to them consists of three elements or many elements alloy filler metals.These products can adopt all kinds of brazing methods.Generally speaking,you should make up the brazing flux in order to get good braze but for the vacuum state operation and the shield gas state operation.
The silver base filler metals include“withcadmium”and“without cadmium”.The silver base filler metals with cadmium have a little toxicity.These products can`t be applied on the brazed joints which are directly connected with food,drinding water.The working place must wind.
Before brazing,you must clear away all dirt on the brazing place and on the surface of object to be brazed such as greasy dirt.oxide,and so on,the best brazed joints space are between 0.03mm to 0.075mm.
釬焊前必須嚴格清除釬焊處及釬料表面的油脂，氧化物等，釬焊接頭的*佳間隙為0.03~0.075mm。
