95WNiFe Heavy Tungsten Alloy Collimator 1400 MPa For Radiation Shielding

Product Description

95WNiFe Heavy Tungsten Alloy Collimator For Radiation Shielding

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.

Introduction and Feature of Heavy Tungsten Alloy Collimator

1. 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.

2. 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.

Application of Heavy Tungsten Alloy Collimator

• 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.
