More info

Bismuth Needle is a brittle metal with a white, silver-pink color and it's stable in both dry and moist air at ordinary temperatures. Bismuth Needle is non-toxicity, low melting point, and can be used as a carbide stabilizer in the manufacturing process for malleable iron. Bismuth Needle also can be added to low-carbon steel or aluminum to improve machinability.
