High Density Tungsten Alloy (W-Ni-Fe) Bucking Bar

W-Ni-Fe tungsten alloy introduction

W-Ni-Fe heavy density alloy, also known as tungsten heavy alloy (WHA), is a composite material composed of tungsten (W), nickel (Ni), and iron (Fe). This alloy is renowned for its exceptional density, high strength, and excellent mechanical and thermal properties.

The primary component of the WHA is tungsten, which provides the alloy with its remarkable density, making it one of the densest materials known. The addition of nickel and iron enhances the mechanical properties of the alloy, including its strength and toughness. The precise composition of the WHA can be tailored to meet specific application requirements, allowing for a range of material densities and mechanical properties.

Due to its high density, WHA is widely used in various industries where weight is a critical factor. It finds applications in aerospace and defense, where it is utilized for radiation shielding, ballast weights, and counterweights for balancing purposes. The high strength and excellent thermal stability of WHA make it suitable for use in vibration dampers, kinetic energy penetrators, and heavy-duty machinery components.

Furthermore, WHA exhibits excellent resistance to corrosion, making it suitable for use in harsh environments. Its exceptional machinability allows for the precise fabrication of complex shapes and components.

QSAMs W-Ni-Fe bucking bar

W-Ni-Fe tungsten alloy bucking bar is a regular product for QSs tungsten product line. W-Ni-Fe is a very important high density tungsten alloys. Compared with steel, bucking bar 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.
