Manufacturing process:

Optimizing raw materials → melting → matching ratio → primary purification → added alloying element → alloying → test → metallurgical structure control → secondary purification → functional testing → casting → furnace after testing → pallet packaging → exterior final inspection → entering warehouse

Bismuth metal is white or reddish, has metallic luster, is brittle, and has poor conductivity and thermal conductivity. Bismuth is the metal with the strongest diamagnetism. Under the action of magnetic field, the resistivity increases while the thermal conductivity decreases. The shapes are rectangular and trapezoidal.
