BrazeTec brazing solder Silfos 94

Hard solders that contain the heavy metal cadmium have excellent technological and processing properties (working temperature of just 610 °C, high silver content not necessary), but are considered hazardous to health. When soldering with cadmium-containing hard leads, the substance calcium oxide can be given off in a smoke-like form and affect the airways. The new technical regulations for hazardous substances TRGS 900 classify cadmium and its compounds as carcinogenic. For this reason, the range of hard solders features only solders that do not contain cadmium.<br>Copper on copper without Defussa h flux<br>Copper on brass, bronze, red brass with flux<br>Not suitable for sulphur-containing materials, not suitable for iron and nickel alloys
