95WNiFe High Density Alloy

The high-density, high-strength, and high-hardness tungsten alloy—affectionately known as the 3H alloy—combines excellent ductility, electrical conductivity, and thermal conductivity, along with other outstanding all-around performance characteristics. Due to these exceptional properties, it has played a significant role in weapon manufacturing and subsequently expanded into defense, aerospace, and civilian industries (such as the electrical and drilling sectors), finding applications across a wide range of fields. As a result, tungsten alloys have become a versatile dual-use material—suitable for both civilian and military purposes. Applications of tungsten alloy include: the defense industry (e.g., armor-piercing bullets), the aerospace sector (e.g., propellant ignition tubes, counterweight blocks), medical applications (e.g., radiation shielding), and civilian uses such as mobile phone vibrators, fish pendants, tungsten wire, and oil drilling counterweights, among others.

Product Description

Tungsten alloy is a type of alloy based on tungsten (with tungsten content typically ranging from 80% to 98%), to which a small amount of Ni, Fe, Cu, Co, Mo, Cr, and other elements that make up alloy materials are added. The density of tungsten alloy ranges from 15.20 to 19.00 g/cm³, and it is also known as tungsten alloys or high-density alloy materials. Tungsten alloy is primarily divided into two series: W-Ni-Fe and W-Ni-Cu, with the latter sometimes including W-Ni-Fe-Cu. Compared to the W-Ni-Fe alloy, this variant boasts superior mechanical properties and plays a critical role in the defense industry as well as in various sectors of the national economy. It is a highly significant new military material in the defense industry and is gradually being introduced for use in civilian applications as well.

The advantage of tungsten alloy

●High specific gravity: the general specific gravity ranges from 16.5 to 18.75 g/cm³;
●High strength: the tensile strength is 700–1000 MPa.
High ray absorption capacity: 30–40% higher than that of lead;
●High thermal conductivity: the thermal conductivity of the tungsten alloy is 5 times greater than that of mold steel;
●Low thermal expansion coefficient: the thermal conductivity of the tungsten alloy is 5 times higher than that of steel.
●Reduced coefficient of thermal expansion: only between 1/2 and 1/3 that of iron or steel
●Good solderability and processability. Good electrical conductivity—not due to its excellent electrical conductivity, but rather because of its widespread use in the lighting and welding industries.
