Tungsten Alloy Machining for High-Density Components
Tungsten heavy alloys pack roughly 1.7× the density of lead into machinable billets — used for radiation shielding, counterweights, vibration damping and kinetic components. They are also abrasive, brittle and unforgiving: tooling choice and cutting strategy decide whether you get a precision part or a cracked one.
Why equipment manufacturers choose us
Machining strategy for a brittle, abrasive alloy
Sharp carbide tooling, rigid setups and conservative parameters manage tungsten's low ductility and rapid tool wear.
Density applications done right
Shielding, balancing and damping parts rely on full-density certified heavy-alloy stock — machined to print, not sinter-to-size guesswork.
Verified on hard material
Zeiss CMM inspection of critical dimensions, with EN 10204 3.1 certificates for raw material.

Materials we machine
From Drawing to Delivered Part
A transparent, engineering-led process built for long-term supply programs — not one-off transactions.
Submit & Review
Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.
Quote & Material Plan
You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.
Machine & Inspect
In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.
Deliver & Support
Kitted, ESD-safe or ISO Class 7 cleanroom packaging, with local engineering and after-sales support through our German partner.
