Heavy Tungsten Alloy Collimator,
95 WNiFe Tungsten Alloy Collimator,
1400 MPa Tungsten Alloy Collimator
Heavy-duty tungsten alloy tanks 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 can reach 15.20~18.70g/cm3, also known as high specific gravity tungsten alloy or high density alloy material. Because tungsten alloy weighs more than twice as much as steel.

Heavy Tungsten Alloy Collimator 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 general lead specific gravity, high thermal conductivity: mold 5 times that of steel; low thermal expansion coefficient: only 1/2-1/3 of steel, good electrical conductivity, good welding and cutting performance.
A common method for making heavy tungsten alloys is to mix the desired amount of tungsten, iron, nickel or copper powders, then cold-press and liquid-phase sintering to near full density. During the liquid phase treatment, the base tungsten alloy melts, and part of the tungsten enters the solution to form a structure, forming larger tungsten particles (20-60 μm), and the structure is dispersed in the base alloy.
Heavy tungsten disks are ideal for shielding x-rays and gamma rays. Extremely high tungsten shielding (60% higher than lead).
Heavy-duty tungsten alloy shields are mainly used in collimators, FDG containers, multi-blade collimators, nuclear shields, beam shields, vial shields, pet syringe shields, isotope containers and other fields.
