Description of High-Density Tungsten Alloy Screws

High-density Tungsten Alloy Screws are often made of tungsten alloy materials after powder metallurgy, sintering processes and other mechanical processing, which can reduce the physical size of important components while providing excellent weight distribution and balance for heavy industrial equipment.

High-density Tungsten Alloy Screws have a high melting point, easy cutting, crack resistance, high tensile strength, high density, high melting point, good impact resistance, strong corrosion resistance, excellent wear resistance, excellent radiation shielding performance and non-toxic No pollution, and other advantages.

High-density Tungsten Alloy Screws are often used to fasten key components and balance weight in aerospace, military defense, smelting and manufacturing, automobile manufacturing, ship engineering, high-temperature industry, and other fields. Our company can provide screws of various shapes.

Features of High-Density Tungsten Alloy Screws

1. Ultra-High Density (Core Advantage)
Density is 16.5-18.5 g/cm³ (close to the 19.3 g/cm³ of pure tungsten), more than twice that of steel screws (7.8 g/cm³) and 1.5 times that of lead screws (11.3 g/cm³).

High weight in a compact package, making it suitable for space-constrained counterweight applications (such as aircraft balancing).

2. High Strength and Wear Resistance
Tensile strength ≥800 MPa, hardness 25-35 HRC, impact resistance, and resistance to deformation (lead screws are prone to creep).

A nickel (Ni) or copper (Cu) binder phase enhances toughness, avoiding the brittleness of pure tungsten.

3. Excellent Corrosion Resistance
Resistant to seawater, acid mist, and salt spray, it requires no protective coating (stainless steel screws require zinc/nickel plating).

Lead-free and non-toxic, it complies with RoHS and REACH environmental standards.

4. Radiation Shielding Performance
High-density tungsten effectively shields X-rays and gamma rays, making it suitable for use in medical and nuclear equipment.
