Tungsten Heavy Alloy Scrap

Tungsten heavy alloy is a liquid-phase sintered tungsten metal matrix bound with a nickel-based binder system. Cemented carbide is tungsten carbide particles bound with cobalt. They are different material families with different recovery routes, and the fact that both are dense and tungsten-bearing does not make them interchangeable.

The practical distinction is visible and tactile. Heavy alloy behaves like a metal: it can be machined, turned and drilled, it takes a metallic finish, and offcuts look like conventional machining scrap. Cemented carbide cannot be machined conventionally and fractures rather than deforms.

Heavy alloy is most often identified by context: a dense metallic part from a known application, supported by the generator's description of what it was. Where certainty matters, elemental screening on a clean surface distinguishes a nickel-bound tungsten matrix from a cobalt-bound carbide, but a surface reading describes the point measured, not the whole lot.

Composition varies by grade and lot; heavy alloys are produced across a range of tungsten and binder contents. Analysis may be arranged where applicable, and any contractual figure is defined in the sales contract.

Heavy alloy machining generates turnings and swarf, which behave differently from solid pieces: high surface area, retained cutting fluid, and a tendency to pick up contamination from the machine. Turnings should be drained and kept separate from solid offcuts so both fractions can be described accurately.

Heavy alloy arises in modest quantities from specialist manufacturing and from equipment withdrawn from service, so parcels are individual rather than continuous. Availability is confirmed at enquiry, and quotations are prepared FOB Rotterdam or CIF to the destination port.

Tungsten heavy alloy is a sintered tungsten-nickel-iron or tungsten-nickel-copper composite used where extreme density is the design requirement: radiation shielding, counterweights and balance masses, vibration-damping tool holders, and kinetic components. Knowing which application a parcel came from is genuinely informative, because the binder system tends to follow the application.

Machining arisings are common in this stream because heavy alloy is usually finish-machined to close tolerance. Turnings from heavy alloy are dense, oily and quite unlike steel swarf in handling, and they are kept as their own drained fraction rather than mixed with solids.

Density dominates every physical decision here. Drums are part-filled because a full drum of heavy alloy is beyond safe handling weight, pallets are loaded with the weight distributed rather than concentrated, and container loading plans have to account for a payload limit being reached with a small stack.
