Is Silver Solder Toxic

High, airborne concentrations of metal fumes, including cadmium, can be expected with silver soldering. Cadmium-containing fumes are extremely toxic, and acute overexposure can cause chemical pneumonia and be fatal. Chronic exposure can cause lung tissue damage, kidney damage, lung cancer, and prostate cancer.

Does solder still contain lead?

Traditionally the solder was an alloy of lead and tin, typically containing about 40% lead. … However, soldering is usually carried out at a temperature of around 380 C and significant lead fume is only evolved at temperatures above 450 C. So exposure by inhalation is normally insignificant.

What is silver lead-free solder made of?
