Tungsten Alloy Syringes For Medical Use
Heavy Tungsten Alloy Syringes are made of tungsten matrix (tungsten content is generally 80%~98%) and a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements. The density of super gravity tungsten alloy is up to 15.20~18.70g/cm3, also known as super gravity tungsten alloy or high density alloy material. Because tungsten alloys weigh more than twice as much as steel.

Tungsten alloy has a series of excellent properties, high specific gravity: general specific gravity 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong light absorption capacity: 30-40% higher than the general lead ratio, high thermal conductivity: 5 times of die steel; Low thermal expansion coefficient: only 1/2-1/3 of steel, good electrical conductivity, good welding and cutting performance.
The common method for preparing heavy tungsten alloys is to mix the desired amount of tungsten, iron, nickel or copper powder and then cold press and liquid phase sintering to near full density. During the liquid phase treatment, the matrix tungsten alloy melts and part of the tungsten enters the solution, forming microstructure and large tungsten particles (20-60m) dispersed in the matrix alloy.
Heavy Tungsten Alloy Syringes are ideal for shielding X-rays and gamma rays. High density tungsten shielding (60% higher than lead).
Heavy tungsten alloy shielding is mainly used in collimator, FDG container, multi-plate collimator, nuclear shielding, beam shielding, vial shielding, PET syringe shielding, isotope container and other fields.
