Product Description

Tungsten Heavy Alloy

Tungsten alloy has played an important role in weapon manufacturing with high density, high strength, high hardness (which is affectionately 3H alloy), good ductility, conductivity, and thermal conductivity. Industrial, aerospace, and civil industries (such as the electrical industry, drilling industry, etc.) have been widely used, high-proportion of tungsten alloy material has become a concern of dual-use alloy materials.


Customized Tungsten Alloys

Heavy tungsten alloys illustrate the advantages of microencapsulated powders. Tungsten heavy alloys generally are refractory metal which has two-phase composites consisting of W-Ni-Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added rare earth and/or other metals like Co, Mo, Cr, etc.
Heavy tungsten alloys have very high melting points have a density twice that of steel and are more than 50% heavier than lead. Tungsten content in conventional tungsten heavy alloys varies from 90 to 98 weight percent and is the reason for their high density (between 16.5 and 19.00g/cc). Nickel, iron and/or copper serve as a metal binder matrix, which holds the brittle tungsten grains together and which makes tungsten alloys ductile and easy to machine. Nickel-iron is the most popular additive, in a ratio of 7Ni:3Fe or 8Ni:2Fe (weight ratio).

The popular processing of preparing tungsten heavy alloys includes mixing the desired amount of elemental tungsten, iron, nickel or copper powders, followed by cold pressing and liquid phase sintering to almost full density. The matrix tungsten alloy melts and takes some tungsten into solution during liquid phase processing, resulting in a microstructure through which large tungsten grains (20-60µm) are dispersed in the matrix alloy. The as-sintered material often is subjected to the mo mechanical processing by swaging and aging, which results in increased strength and hardness in the heavy tungsten alloys. The majority of current uses for heavy tungsten alloys are best satisfied with the W-Ni-Fe system. Tungsten alloys such as 93W-4.9Ni-2.lFe and 95W-4Ni-lFe represent common compositions. The addition of cobalt to a W-Ni-Fe alloy is a common approach for slight enhancement of both strength and ductility. The presence of cobalt within the tungsten alloys provides solid-solution strengthening of the binder and slightly enhanced tungsten-matrix interfacial strength. Cobalt additions of 5 to 15% of the nominal binder weight fraction are most common. Some photos of tungsten alloys from China tungsten.
