Ultra-fine tungsten wire is a filament made of tungsten, its diameter is usually less than 0.01mm. It has high melting point, high hardness, low electrical conductivity and good mechanical properties, so it shows excellent performance in high temperature and high current application scenarios. Ultra-fine tungsten wire is usually made using powder metallurgy technology and has high density and good surface quality. It is also widely used in medical technology, such as surgical robots, stents, guide wires for catheter surgeries and electrosurgery, and as medical wires for brain stimulation and neuronal research components.
The manufacturing process of ultra-fine tungsten wire includes a series of complex processes, including preparation of tungsten powder, pressing, sintering, processing and heat treatment. These processes require precise control of parameters such as tungsten particle size, purity, density and grain structure to ensure the high quality and performance of ultra-fine tungsten wire.
The application of ultra-fine tungsten wire in the medical field benefits from its high melting point, high hardness, low conductivity and good biocompatibility. It can be used to make medical instruments such as scalpels, surgical scissors, and surgical forceps, as well as medical products that are long-term implanted in the human body, such as medical implants and artificial joints.
In short, ultra-fine tungsten wire is a filament material with excellent properties. It shows good performance in high-temperature and high-current application scenarios, and has broad application prospects in the field of medical technology.
