Tantalum Sheet & Plate

Because each end use has different material property requirements, Admat has developed unique manufacturing processes for each application. By adjusting our production processes, we can control mechanical properties, grain size, texture and chemistry of the final products.

Our deep draw quality (DDQ) sheet is a perfect example in which we manage the delicate balance of grain size and certain mechanical properties. Furthermore Admat offers a wide selection of tantalum alloys, each developed to enhance certain material properties.

Our tantalum 2.5% tungsten sheets and plates are designed to survive in corrosive environments, while our tantalum 10% tungsten alloy is designed for high temperature corrosive environments. We also have furnace grade tantalum that has small amounts of additives to slow grain growth and improve life in vacuum furnaces.

Our Tantalum sheet and plate is sold for use in a wide variety of industries including:

  • Semiconductor and electronics
  • Defense
  • Furnace parts and rigidized sheets and plate
  • Chemical processing
  • Medical
