Properties of tungsten nickel iron alloy (W-Ni-Fe Alloy):
- High density (16.85-18.85g/cm3)
- High melting point
- Wear resistance
- High tensile strength
- Good elongation capacity
- Low vapor pressure
- Excellent thermal stability
- High radiation absorption capacity
- Slightly Magnetic
Because of these unique characteristics, they are widely used in various fields including the sports, industry and medical equipments. The most common high density tungsten alloys are W-Ni-Fe Alloy and W-Ni-Cu Alloy. XI'AN KEFENG POWDER METALLURGY CO., offers different kinds of tungsten heavy alloy products, we also manufacture them according to clients' specifications.

Compared to traditional radiation shielding materials, tungsten alloys provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material! Unlike lead, you'll also reduce administration costs by eliminating the need to obtain special licensing-it's not required. Our products are available as finished machining parts or as short rod, round bar, rectangular blocks and other shapes per your requirements and drawings.
Characteristics and features
As medical science developing, there is more and more radiation in our life, which has become a new trouble, such as X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc. In order to protect patients and other people safe from harmful effects of ionizing radiation, such as breast cancer, skin cancer, etc. One type of excellent radiation-absorbing medium is badly needed.
Experts find that radiation exposure could be reduced by maxing shielding. The density of a material is related to its radiation stopping ability. Higher density means better stopping power and shielding. With a higher density, tungsten alloy has a greater protection than lead. It is greater linear attenuation of gamma radiations means that less is required for equal shielding. Alternatively equal amounts of tungsten alloy shielding provide diminished exposure risks than equivalent lead shielding.
- Can be machined to different shapes per customer drawings and requirements.
- Good corrosion resistance
- High radiation absorption (superior to lead)
- Simplified life cycle and high strength.
- Non-toxic material as a replacement to lead
