Bismuth has many interesting properties. It has a relatively low melting point of approximately 520 degrees Fahrenheit, making it useful for alloying with other metals.The bismuth thermal conductivity is very low, expanding, cooling, with extremely high diamagnetic value.Mainly used in the production of bismuth alloy, medicine, chemical reagent, base melting point alloy, nuclear reactor coolant and so on.Also widely used in semiconductor, superconductor, flame retardant, pigment, cosmetics, electronic ceramic lamp field.Bismuth is used to grow beautiful iridescent hopper crystals used in jewelry and art.Bismuth is a non-toxic and environmentally friendly substitute for lead.Specifications:Product name: bismuth ingotBismuth content :≥99.99(%)Density: 9.8/cm³Melting point: 271 CelsiusColour:multicolorMaterial:Bismuth ingotPackage Contents:5 x 1000g BismuthOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
