Lead-Bismuth Alloy

Lead-bismuth alloy is used for low-melting alloys and to produce pure bismuth and lead.

The pure metals that arise after refining lead-bismuth alloy are applied to different purposes. While lead is primarily used in the battery industry, bismuth serves as a compound in the pharmaceutical industry and as a catalyst in the chemical industry. Moreover, bismuth is used to product pigments, lacquers, and paints, as well as to manufacture thermoelectric appliances.

Both lead-bismuth and lead-antimony litharge from Aurubis fulfill the REACH requirements.
