Emil Otto is aiming at joining steel, stainless steel, brass and copper objects below 450°C with three tin-based soft-soldering pastes. “The soldering and tinning pastes do not require zinc chloride, ...

Lead-free solder alloys have been around for as long as people have done soldering, with sources dating back about 5,000 years. Most of these alloys were combinations like copper-silver or silver-gold ...
