Product Introduction
Explanation of Tungsten Needle
A tungsten needle is a thin and sharp tool made of tungsten metal. It is usually used in various applications that require high temperature, high wear resistance, and high hardness. The following is a detailed description of tungsten needles:
Material: tungsten needle is mainly composed of tungsten metal (Chemical symbol is W). Tungsten is a high melting point metal with high density, high hardness, and high corrosion resistance.
Shape: The shape of a tungsten needle is usually a slender cylindrical or conical shape. Sharp and fine at one end, suitable for fine operation.
Features: Tungsten needles have several important characteristics, including:
High melting point: The melting point of tungsten is very high, about 3422 ° C, allowing the tungsten needle to be used for a long time in high-temperature environments without melting.
High hardness: Tungsten has a very high hardness and can maintain its shape and sharpness under friction and wear.
High density: Tungsten is a dense metal with a relative density of 19.3 g/cm3, which gives tungsten needles high quality and strength.
Corrosion resistance: Tungsten has good corrosion resistance in various chemical environments and is not easily affected by corrosion and oxidation.
Application of Tungsten Needle
Application field: Tungsten needles are generally widely used in the following fields:
Laboratory and scientific research: Used for fine experiments or operations, such as sample preparation for electron microscopy, nanotechnology research, etc.
Medical equipment: used for medical operations such as surgery and injection, such as cell culture, skin sampling, etc.
Electronic industry: used for the manufacturing and repair of electronic devices, such as semiconductor assembly, circuit welding, etc.
Precision machining: used for precision operations such as metal processing, cutting, and piercing.
It should be noted that tungsten needles, due to their sharpness and robustness, require careful handling during use and handling to prevent accidental injury.
