Tantalum Refractory Metal Machining

I have a tungsten or molybdenum part and my usual machine shop turned it down. Who will actually cut it?

What it is

Machining, EDM, waterjet cutting and grinding of tungsten, molybdenum, tantalum and niobium. A distinct capability from general CNC work: these metals are brittle at room temperature, punishing on tooling, and most job shops will decline them outright.

  • Lewiston, ME · Mill Converter Service provider
    AS9100

    Refractory machining capability; confirm tantalum-specific experience for your geometry. Elmet machines refractory metals broadly and offers a Mo-Ta alloy, but their materials overview does NOT list standalone tantalum mill product. Confirm tantalum-specific experience before assuming it.

  • Columbia, NJ · Service provider
    AS9100

    Tantalum named explicitly among the refractory materials worked. Refractory metals are brittle at room temperature and hard on tooling; confirm they have run your specific metal and geometry before committing.

  • Mayfield Heights, OH · Mill Converter

    Machining named within the vertically integrated in-house tantalum process. IMPORTANT SCOPE LIMIT: this is semiconductor thin-film deposition material, not structural or chemical-process tantalum. Forms are targets, plates, coils and pots. Sheet, foil, rod, tube and wire are not named. And while the material is sourced from Newton, Massachusetts, the finished targets are produced at a South Korean plant, so this is not an end-to-end domestic supply chain.

  • Albany, OR · Service provider
    AS9100

    Tantalum is named first among the materials machined. Tantalum galls and tears under the tool, so this is a distinct skill rather than harder machining.

  • Willowbrook, IL · Converter Service provider

    Refractory metals are brittle at room temperature and hard on tooling; confirm they have run your specific metal and geometry before committing.

  • Dobbs Ferry, NY · Distributor Service provider

    Refractory metals are brittle at room temperature and hard on tooling; confirm they have run your specific metal and geometry before committing. Precision machining and forming of refractory components, plus a rapid prototyping service.
