Tantalum Plate

Who makes or stocks plate in this alloy, and can I get it US-melted?

What it is

Flat rolled product above the thickness threshold that separates it from sheet, supplied in the mill-annealed or as-rolled condition and typically sold by the pound from a cut plate.

Typical dimensions
0.1875 inch and thicker; widths to roughly 120 inches depending on mill.
Also known as

Grouped by what they actually are. A mill and a distributor answer different needs.

Mills and producers 2

Companies that manufacture this form. Mill direct means longer lead times and mill minimums, with full melt traceability.

  • Boyertown, PA · Mill
    US melted

    Tantalum plate among the metallurgical products. Made by an electron beam melted ingot route at Boyertown, the only fully integrated tantalum and niobium producer in the United States. Note that tantalum falls under Dodd-Frank Section 1502 conflict minerals due diligence, not DFARS specialty metals; this plant was conflict-free audited in 2010.

  • Mayfield Heights, OH · Mill Converter

    Tantalum plate at greater than 99.995 percent purity, internally fabricated and used as the input to finished sputtering targets. Two microstructure routes are offered, melted and sintered. 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.

Distributors and stockists 1

Companies that hold inventory for resale. Faster and available in small quantities, at a markup. Ask what mill the material came from if traceability matters.

  • Dobbs Ferry, NY · Distributor Service provider

    Distributor stock. Establish grade and mill certification per heat rather than from the catalog listing.
