Specialty Alloy Processing
Tungsten Alloys Processing
& Global Supply
Operating from Singapore, ABCOM sources, processes, and supplies specialty tungsten alloys — ultra-high density, high melting point materials including Hevimet and Mallory grades — to industrial buyers and recyclers across Europe, Asia, and the Americas. Our 25-year track record in non-ferrous metal flows underpins every transaction.
Material Overview
What Are Tungsten Alloys?
Tungsten alloys are high-performance metallic materials built around tungsten — the metal with the highest melting point of any pure element (3,422°C). Combined with binders such as nickel, iron, copper, or cobalt, tungsten forms heavy alloys with ultra-high density (typically 17–18.5 g/cm³), exceptional hardness, and outstanding thermal stability. The result is a material class that performs in environments where no other metal does.
The industrial significance of tungsten alloys stems from their unique combination of density, hardness, and high-temperature retention of mechanical properties. Where standard steels deform and even nickel super alloys reach their limits, tungsten heavy alloys continue to deliver — making them essential for kinetic energy applications, radiation shielding, high-temperature tooling, and precision balancing components.
ABCOM trades and processes a broad range of tungsten alloy scrap and primary forms — including W-Ni-Fe, W-Ni-Cu, sintered preforms, machined components, and graded scrap streams. Our technical expertise in identification and sorting ensures that material entering downstream supply chains meets the compositional requirements of foundries, sintering operations, and alloy producers.

End Markets
Industries & Applications
Aerospace
Counterweights, gyroscope components, vibration dampeners, and balancing weights rely on tungsten alloys' ultra-high density to deliver mass in compact volumes — critical where space and weight distribution matter.
Defence
Kinetic energy penetrators, armour-piercing cores, and radiation shielding components specify tungsten heavy alloys for their density, hardness, and self-sharpening behaviour under high-velocity impact.
Medical
Radiation shielding in X-ray, CT, and radiotherapy equipment uses tungsten-based alloys such as Hevimet as a non-toxic, high-attenuation alternative to lead — essential for collimators, multileaf collimators, and isotope containers.
Oil & Gas
Drilling tools, downhole logging equipment, and bottom-hole assemblies benefit from tungsten alloys' density, hardness, and wear resistance — performing reliably in abrasive, high-pressure subsurface environments.
Industrial Manufacturing
EDM electrodes, die-casting dies, hot-working tooling, and forging inserts use tungsten alloys for their thermal stability, hardness retention at elevated temperatures, and resistance to deformation under repeated thermal cycling.
Electronics
Heat sinks, high-temperature electrical contacts, and semiconductor processing components leverage tungsten's combination of low thermal expansion, high melting point, and excellent thermal conductivity for demanding electronic and power applications.
Material Categories
Grades We Supply
Hevimet
Hevimet is a high-density tungsten heavy alloy — typically a W-Ni-Fe or W-Ni-Cu composition — used widely for counterweights, radiation collimators, and shielding components. Its combination of density (17–18.5 g/cm³), machinability, and non-toxicity makes it a standard specification across aerospace, defence, and medical imaging applications.
Mallory
Mallory is a proprietary family of tungsten heavy alloys recognised for their machinability, dimensional stability, and high density. Mallory grades are routinely specified for precision counterweights, balancing components, and shielding parts where tight tolerances and consistent material performance are critical.
Supertherm
Supertherm is a tungsten-based alloy engineered for extreme high-temperature service. Its retained strength and oxidation resistance at sustained elevated temperatures make it a material of choice in furnace internals, high-temperature aerospace components, and other thermally demanding industrial environments.
NA 22H
NA 22H is a specialised tungsten alloy grade applied in high-temperature and radiation-resistant applications. Its compositional balance supports performance in aerospace, defence, and shielding contexts where conventional heat-resistant alloys cannot meet the combined density and thermal requirements.
Other Tungsten Alloy Grades
Beyond the named grades above, ABCOM handles additional tungsten alloy compositions and form factors on inquiry — including custom W-Ni-Fe, W-Ni-Cu blends, sintered preforms, machined parts, and scrap streams from aerospace, defence, and industrial decommissioning. Contact us for grade-specific requirements.
Our Capabilities
Processing & Recycling
ABCOM operates processing facilities in Singapore and Turkey, where incoming tungsten alloy material is sorted, graded, and prepared to the compositional specifications required by downstream buyers. Our technical team evaluates each lot by alloy family — W-Ni-Fe, W-Ni-Cu, tungsten-cobalt blends — and by form factor and contamination level before classification.
Tungsten alloy scrap recovered from aerospace, defence, and industrial decommissioning is a significant focus. These streams contain grades such as Hevimet and Mallory — high-density materials whose tungsten content commands strong recycled value because of tungsten's global scarcity, concentrated mining supply, and consistent industrial demand. Proper grading ensures maximum recovery and accurate pricing.
Quality control is applied at each stage of the process. Material is documented and traceable from origin through to dispatch, supporting the compliance and traceability requirements of our defence, aerospace, and manufacturing customers. Learn more about our operations on the about page.

Common Questions
Frequently Asked Questions
What are tungsten alloys used for?
Tungsten alloys are used in applications requiring extreme density, hardness, and high-temperature performance. Common uses include aerospace counterweights, gyroscope components, defence kinetic energy penetrators, radiation shielding for medical imaging, oil and gas downhole tools, EDM electrodes, and high-temperature electrical contacts in electronics.
What is Hevimet?
Hevimet is a high-density tungsten heavy alloy — typically a tungsten-nickel-iron or tungsten-nickel-copper composition (W-Ni-Fe / W-Ni-Cu) — engineered for applications such as counterweights, collimators, and radiation shielding. Its combination of ultra-high density (around 17–18.5 g/cm³), machinability, and non-toxicity makes it a widely specified alternative to depleted uranium and lead in shielding applications.
Why is tungsten so valuable?
Tungsten is one of the rarest and most strategically important industrial metals. It has the highest melting point of any pure metal (3,422°C) and an exceptionally high density. Limited global mining supply, concentrated production geography, and consistent demand from defence, aerospace, and tooling industries combine to make tungsten and tungsten alloy scrap consistently high-value materials.
What industries use tungsten alloys?
Primary industries include aerospace, defence, medical (radiation shielding), oil and gas, industrial manufacturing, and electronics. Any sector requiring ultra-high density, high-temperature stability, or radiation attenuation typically specifies tungsten-based materials over conventional alloys.
What is tungsten alloy recycling?
Tungsten alloy recycling involves collecting, sorting, and processing scrap containing tungsten, nickel, iron, copper, and cobalt back into usable raw material. Because primary tungsten supply is limited and concentrated geographically, recovered tungsten alloy carries strong economic and strategic value. ABCOM specialises in grading and processing these scrap streams from aerospace, defence, and industrial decommissioning for re-entry into supply chains.
