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.
Sharp carbide tooling, rigid setups and conservative parameters manage tungsten's low ductility and rapid tool wear.
Shielding, balancing and damping parts rely on full-density certified heavy-alloy stock — machined to print, not sinter-to-size guesswork.
Zeiss CMM inspection of critical dimensions, with EN 10204 3.1 certificates for raw material.
