Cadmium Silver Solder

At first i didn t realize what was going on.

Cadmium silver solder.

I prefer cadmium bearing silver solder. Flux is necessary for brazing to remove and prevent reformulation of surface oxides on the base metals. In 2001 i took a job to silver solder three thousand parts made of stainless steel. What is the best composition for it.

Silver cadmium alloys wire sheet contacts oxide etc. Choose from our selection of silver solder including brazing alloys without cadmium solder for stainless steel and more. Cadmium is a silver white ductile metal which melts. I am proof of that.

At 320 c and when heated above this temperature in air produces cadmium oxide fumes. Need to use flux with stainless though. In stock and ready to ship. Silver brazing uses filler metals and alloys such as silver copper zinc cadmium etc.

Health effects of cadmium in silver solders. However a few hours after soldering with it i ve felt achy and out of sorts. In there a real risk using cadmium. I thought i always used good ventilation.

But it finally dawned on me that cadmium was the culprit. Serious health effects on the lungs and kidneys are the principal concerns. No flux needed when soldering copper the stuff the plumbers use on water or gas. Afaik the silver solder i use is 2 ag and copper.

Nimrod77 wrote is it possible to tell which silver solder contains cadmium and which doesn t. He uses 3 g of cadmium powder silver and copper and mix all of them in his hand. You can send us the following silver cadmium scrap to be refined and recycled. Cadmium solder and flouride fluxes cadmium in solder and fluorides in fluxes can kill you.

But cadmium is poisonous. Ii silver brazing alloys cadmium is an important component in quaternary alloys with silver copper and zinc in the lower temperature range of brazing alloys. Zinc cadmium alloys are useful for soldering aluminium whilst cadmium zinc tin alloys are used for soldering magnesium. Kappcad cadmium zinc solders are medium temperature alloys that provide strong corrosion resistant joints on most metals making them an excellent choice for soldering dissimilar metals these solders are often used in applications requiring higher temperatures and superior strength joints especially aluminum to aluminum and aluminum to copper joints in electronics lighting and.

I want prepare a low melting point solder. Silver contacts from electrical equipment clean silver contacts on bus bars buss bars busbars etc. Silver brazing produces strong sealed leak proof joints on. Acute immediate effects initial symptoms from.
