Woodi sulam sisaldab: 50% vismutit, 26,7% pliid, 13,3 % tina ja 10% kaadmiumi.
Sulab alla 70°C – seetõttu ei sobi elektroonikasse. Vanasti kasutati tuletõrjeandurites.
EL on Pb ja Cd alates 2011.a. keelatud!
Vismut on halva soojusjuhtivuse, suure elektritakistusega, omab Halli efekti.
Bismuth is a white, crystalline, brittle metal with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal, except mercury. It has a high electrical resistance, and has the highest Hall effect of any metal (that is, the greatest increase in electrical resistance when placed in a magnetic field).
