银基钎料silver base filler metals |
使用说明 operation introduction
银基钎料是一种以银或银基固熔体的钎料。具有优良的工艺性能，不高的熔点，良好的湿润性和填满间隙的能力，并且强度高，塑性好，导电性和耐蚀性优良，可以用来钎焊所有黑色和有色金属，如不锈钢，硬质合金、金钢石等各种材料。广泛应用于制冷、灯饰、五金电器、仪器仪表、化工、航空航天等工业制造领域。
为了降低熔点及减少银含量，加入铜、锌、镉、镍、锡等构成三元或多元合金钎料。银钎料适用于各种钎焊方法，但除在真空或保护气氛中钎焊以外，一般要配合银钎剂共同使用，方可获得优良的钎缝。
银基钎料按其成分构成可分为无镉钎料和含镉钎料。含镉钎料具有一定的毒性，不适宜用于食物，饮用水直接接触接头的钎焊。钎焊工作点需通风。
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 e 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. |
钎焊前必须严格清除钎焊处及钎料表面的油脂，氧化物等，钎焊接头的间隙为0.03~0.075mm。
