95WNiFe Tungsten Pots,
Tungsten Pots For Radioactive Shields
Heavy Tungsten Alloy Pots 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 high specific gravity tungsten alloy is up to 15.20~18.70g/cm3, also known as high specific gravity tungsten alloy or high density alloy material. Because tungsten alloys weigh more than twice as much as steel.

Heavy Tungsten Alloy Pots Picture:
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 specific gravity, high thermal conductivity: 5 times of die steel; Low thermal expansion coefficient: only 1/2-1/3 of steel, good electrical conductivity and 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, part of the tungsten enters the solution, forming microstructure and large tungsten particles (20-60μm), and the microstructure is dispersed in the matrix alloy.
Heavy tungsten pans are ideal for shielding x-rays and gamma rays. Very high density tungsten shielding (60% higher than lead).
Heavy-duty tungsten alloy shielding is mainly used in collimator, FDG container, multi-blade collimator, nuclear shielding, beam shielding, vial shielding, PET syringe shielding, isotope container and other fields.
