Bismuth Balls
Overview
Bismuth balls offer environmental friendliness, non-toxicity, high density, and excellent X-ray absorption properties. Their characteristic volume expansion during solidification renders them suitable for precision casting, mould manufacturing, and radiation shielding applications.
Our company supplies diverse non-ferrous metal products, including tungsten alloys, titanium alloys, nickel alloys, molybdenum copper, and platinum-iridium alloys. Through high-quality service support, exceptional customisation capabilities, and authoritative quality assurance, we have established collaborative relationships with numerous overseas nations.

Bismuth Features
| vs lead balls |
① Non-toxic and environmentally friendly, posing no health or environmental risks; ② Exhibits reverse expansion during solidification, resulting in superior mouldability; ③ Superior corrosion resistance compared to lead (which is susceptible to corrosion by weak acids). |
| vs steel balls |
① Higher density, delivering superior weighting performance for equivalent volumes; ② Rust-free, with outstanding corrosion resistance; ③ Low thermal conductivity, ideal for thermal insulation applications. |
|
vs tungsten balls |
① Lower cost; ② Lower melting point, making it far easier to process than tungsten; ③ Superior plasticity, facilitating composite fabrication and welding. |
| vs copper balls |
① Significantly higher density than counterweights and shielding, with outstanding core advantages; ② Enhanced corrosion resistance, coupled with low thermal conductivity and low electrical conductivity, makes it suitable for specialised applications. |

Bismuth Balls Application
- Nuclear Industry and Radiation Shielding: Due to their high atomic number, Bismuth Balls offer excellent absorption of X-rays and gamma rays, making them suitable for use in protective equipment in medical devices and nuclear power plants. They also present a more environmentally friendly alternative to lead.
- Medical and Biomedical Applications: Employed in CT imaging, radiotherapy enhancement, targeted tumour drug delivery, and photothermal or photoacoustic therapy.
- Electronics Industry: High-purity bismuth balls are utilised in the manufacturing of low-melting-point alloys and lead-free solders for fuses, thermistors, and chip packaging, enabling rapid and stable sodium/lithium storage in battery anode materials.
- Chemical Processing and Catalysis: Functioning as catalysts or carriers, they participate in reactions for pharmaceutical intermediates, dyes, and polymerisation.
- Scientific Research and Experimentation: Employed in superconducting materials, quantum computing, and novel functional material research.
Processing
① Crush high-purity bismuth ingots, acid-wash them and weigh them.
② Melt the bismuth material, ensuring uniform composition through mechanical stirring.
③ Pour the refined bismuth liquid into preheated mould cavities, forcibly cooling it to form the shape.
④ Perform surface treatment via mechanical polishing to enhance surface finish.
⑤ Conduct purity testing, flow property testing and dimensional accuracy checks to ensure finished product quality.
