Tungsten needles are available in a wide range of sizes and diameters, depending on the specific application. Here are some common sizes of tungsten needles:
Micro-needles: These are tungsten needles with diameters ranging from a few micrometers to a few hundred micrometers. They are used in microscale applications, such as microelectromechanical systems (MEMS), biosensing, and microfluidics.
Small needles: These are tungsten needles with diameters ranging from a few hundred micrometers to a few millimeters. They are often used in medical applications, such as acupuncture and hypodermic needles.
Large needles: These are tungsten needles with diameters ranging from a few millimeters to several centimeters. They are often used in industrial applications, such as welding, plasma cutting, and thermal spraying.
Ultra-fine needles: These are tungsten needles with diameters less than 1 micrometer, often referred to as nanoneedles. They are used in cutting-edge applications such as nanotechnology, scanning probe microscopy, and nanoelectronics.
The size of the tungsten needle used in a particular application depends on factors such as the desired level of precision, the material being worked on, and the intended use of the needle. In general, smaller needles are used for microscale applications, while larger needles are used for macroscopic applications.
