Types of Tungsten Alloys

Tungsten Nickel Copper

The tungsten nickel-copper alloys have great mechanical strength and excellent electrical conductivity and are simple to produce. They can shield from radiation and have great thermal stability. Tungsten nickel-copper alloys are less ductile than nickel-iron alloys. However, they are not magnetic, making them a good substitute in some contexts. Oncology instruments, electrical sensor shields, guidance system components, and military technology use tungsten nickel copper.

Tungsten Carbide

The most significant tungsten alloy is tungsten carbide. It is also known as a tungsten-cobalt alloy because it consists of tungsten, carbon, and cobalt. Tungsten carbide (also referred to as "industrial teeth") is hard, strong, and corrosion-resistant. Cutting tools, blades, cobalt tools, and wear-resistant components are all made with carbide.

Carbide is currently used extensively in the aerospace and military industries. Demand will continue to increase with future developments of high-tech weaponry and technology.

Tungsten Nickel Iron Alloy

Tungsten nickel-iron alloys are superior in ductility, strength, and density. These alloys can endure extremely high temperatures, have good machining properties, and have a thermal conductivity five times greater than die and punch steels. If these alloys are intended to be used in magnetism-sensitive procedures, such as medical imaging equipment, it is crucial to understand that iron makes them magnetic. Tungsten nickel-iron alloys are resistant to elastic deformation and, therefore, ideal for glass-to-metal sealing. These alloys work well for radiation shielding, ballasts, bearing assembly, defense applications, and balance weights.

Applications of Tungsten Alloys

• Permanent magnets: Tungsten steel is used to create permanent magnets. A metal's or alloy's magnetic characteristics are highly sensitive to microstructure. When tungsten is present in steel in these proportions, for instance, it stabilizes the martensite phase, which has higher ferromagnetism than the ferrite (iron) phase due to its greater resistance to magnetic domain wall motion, although tungsten is not a ferromagnetic element.
• Industry: Tungsten is primarily used to manufacture tungsten carbide (WC), one of the toughest carbides. Tungsten carbide is used by metalworking, woodworking, mining, petroleum, and construction industries to create wear-resistant abrasives and cutting instruments such as knives, drills, circular saws, dies, milling, and turning tools. About 60% of the world's tungsten consumption is currently attributed to this industrial use.
• Jewelry: The jewelry industry produces rings made of sintered tungsten carbide, tungsten carbide/metal composites, and metallic tungsten. Nickel is used as the metal matrix in WC/metal composite rings rather than cobalt because it takes on a higher sheen when polished. Tungsten carbide is ceramic, even though producers and merchants occasionally refer to it as a metal. Rings constructed of tungsten carbide are exceptionally abrasion resistant and will maintain a burnished polish longer than rings made of metallic tungsten. However, tungsten carbide rings are fragile and may break when struck hard.

Choosing the Proper Tungsten Alloy Supplier

To make sure you have the most productive outcome when purchasing tungsten alloys from a tungsten alloy supplier, it is important to compare at least 4 to 5 suppliers using our tungsten alloy directory. Each tungsten alloy supplier has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the supplier for more information or request a quote. Review each tungsten alloy company website using our patented website previewer to get an idea of what each company specializes in, and then use our simple RFQ form to contact multiple tungsten alloy companies with the same form.
