Cadmium solder was extensively used throughout the 20th century in electronics, aerospace, and plumbing industries. Due to cadmium's toxicity and carcinogenic properties, it has been largely phased out and replaced with lead-free alternatives, particularly following RoHS (Restriction of Hazardous Substances) directives in the EU and similar regulations globally. Its use is now restricted or banned in many countries, though it may still be encountered in vintage equipment repair and restoration work.
