Product Description

90WNiFe Heavy Tungsten Alloy Syringe For Nuclear Shielded Use

Heavy Tungsten Alloy Syringe is made of tungsten matrix (tungsten content is generally 80%~98%) and a small amount of nickel, iron, copper, cobalt, molybdenum, chromium and other elements.High gravity tungsten alloy density as high as 15.20~18.70g/cm3, also known as high gravity tungsten alloy or high density alloy material.Because the tungsten alloy weighs more than twice as much as the steel.

Introduction and Feature of Tungsten Alloy Syringe

  1. Tungsten alloy has a series of excellent properties, high proportion: 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 proportion, high thermal conductivity: 5 times of mold steel; low thermal expansion coefficient: only 1 / 2-1 / 3 of steel, good conductivity, good welding and cutting performance.

  2. A common method for preparing heavy tungsten alloys is to mix the desired amount of tungsten, iron, nickel or copper powder and then cold pressure 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 to form microtissue and large tungsten particles (20-60 m), which are dispersed in the matrix alloy.

Application of Tungsten Alloy Syringe

  • Heavy duty tungsten disks are ideal for shielding X-rays and gamma rays. High density tungsten shielding (60% higher than lead).

  • Heavy-duty 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.
