High Density Tungsten Alloy (W-Ni-Fe) Rod

W-Ni-Fe tungsten alloy introduction

W-Ni-Fe, also known as tungsten-nickel-iron heavy density alloy, is a composite material renowned for its exceptional density, strength, and resistance to high temperatures. This alloy is primarily composed of tungsten (W) particles embedded in a matrix of nickel (Ni) and iron (Fe).

The addition of tungsten provides W-Ni-Fe with its remarkable density, making it one of the densest materials known. Its high density makes it an ideal choice for applications requiring weight or mass concentration, such as counterweights and balancing components in various industries.

W-Ni-Fe alloys offer excellent mechanical properties, including high tensile strength, hardness, and ductility. These alloys are known for their exceptional resistance to deformation, even under extreme conditions. They exhibit remarkable stability and retain their structural integrity at elevated temperatures, making them suitable for applications in high-temperature environments, such as aerospace and defense industries.

Another notable characteristic of W-Ni-Fe alloys is their excellent radiation shielding capacity. The high density of tungsten combined with the cohesive matrix of nickel and iron effectively attenuates and absorbs radiation, making these alloys widely used in medical and nuclear industries for radiation shielding applications.

W-Ni-Fe alloys can be fabricated through various processes, including powder metallurgy techniques. The composition of the alloy can be tailored to meet specific requirements, allowing for customization of its properties.

QSAMs W-Ni-Fe rod

W-Ni-Fe tungsten alloy rod is a regular product for QSs tungsten product line. W-Ni-Fe is a very important high density tungsten alloys. Compared with steel, rod has much higher thermal conductivity with much smaller thermal expansion coefficient. The application of W-Ni-Fe high density tungsten alloys are focused on its high density and hardness. Thus, tungsten alloy has been the most important material for armor piercing shell and fragments. It also consumed in large quantity as cutting tools and aviation industries.
