To specification
Custom W/Cu Parts
Near-net shapes and special profiles
Low-tungsten (<80% W) alloys only · No MOQ · Lead time 10–14 days
Overview
Made by infiltration, finished by machining
Send a drawing and we quote it: shaped infiltrated blanks, profiled segments, composite assemblies, and special geometries in W/Cu 75/25 or 70/30. Tooling and machining are quoted per part — no hidden minimums.
Note: we supply alloys below 80% tungsten only. This keeps every shipment outside dual-use export controls and clears routine customs handling.
Material values shown are typical for the grade. Per-batch composition, density and hardness reports are provided on request — see quality control.
