Bismuth has a density of 9.8 g\/cm\u00b3, a melting point of 271.3\u00b0C, and a boiling point of 1560\u00b0C. It is brittle, with poor electrical and thermal conductivity. As a strongly diamagnetic metal, bismuth&#8217;s resistivity increases and its thermal conductivity decreases in a magnetic field. Bismuth lump is widely used in various fields, especially in environments requiring low melting points, chemical stability, and magnetic materials, showcasing its unique advantages.<\/p>\n<p><strong>Product Features<\/strong><\/p>\n<ul>\n<li><strong>High Purity:<\/strong>4N purity, ensuring optimal performance in precision and high-demand applications<\/li>\n<li><strong>Low Melting Point:<\/strong>Melting point of 271.3\u00b0C, suitable for firefighting devices and automatic melting applications<\/li>\n<li><strong>Strong Chemical Stability:<\/strong>Exhibits excellent chemical stability in various environments, ensuring long-term use in complex industrial conditions<\/li>\n<li><strong>Diamagnetic Properties:<\/strong>With diamagnetic characteristics, its resistivity increases and thermal conductivity decreases in magnetic fields, ideal for specific industrial applications<\/li>\n<\/ul>\n<p><strong>Applications<\/strong><\/p>\n<ul>\n<li><strong>Firefighting Devices:<\/strong>Alloys of bismuth with lead, tin, antimony, and indium are used in automatic sprinklers and boiler safety plugs.
