Heavy Tungsten Alloy Syringes For Medical UseHeavy 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.

Heavy Tungsten Alloy Syringes Picture:
Introduction and Feature of Heavy Tungsten Alloy SyringesTungsten 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.
Application of Heavy Tungsten Alloy SyringesHeavy 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.
