We supply niobium discs and blocks on request and can also be processed according to drawings. Niobium metal discs are cut from sheets and plates and can also be made from blocks and ingots if the thickness is larger.

Specifications of niobium discs and niobium sputtering targets

Specifications: According to ASTM B393

Material: R04200-1, R04210-2, purity 99.9% and 99.95%, target purity 99.99%

Dimensions: Diameter 5mm-600mm x thickness 0.5mm-20mm

Standard specifications for niobium and niobium alloy discs 

  1. ASTM B 393-05 UNS R04200 – Type 1, Reactor Grade Unalloyed Niobium;
  2. ASTM B 393-05 UNS R04210 – Type 2, Commercial Grade Unalloyed Niobium;
  3. ASTM B 393-05 UNS R04251 – Type 3, Reactor Grade Niobium Alloy with 1% Zirconium;

  5. ASTM B 393-05 UNS R0xxxx – Type 5, Residual Resistivity Ratio (RRR) Grade Pure Niobium.

RRR Value: Guaranteed minimum value RRR 260 *,

* Residual Resistivity Ratio RRR is defined as the ratio of 295K resistivity to 4.2K resistivity.

Thicker disks will be referred to as cylinders, blocks, etc.

Niobium Disc Applications

  1. Chemical Processing: Used as corrosion-resistant discs in reactors, valves, and pumps that handle corrosive chemicals in chemical plants.
  2. Electronics: Used as substrates for electronic components such as sensors, capacitors, and integrated circuits due to its excellent conductivity and stability.
  3. Aerospace: Used in aircraft and spacecraft components such as bearings, valves, and thrust chambers due to its high strength-to-weight ratio and high-temperature resistance.
  4. Medical Devices: Used in medical implants such as pacemakers and orthopedic implants due to its biocompatibility and resistance to body fluids.
  5. Precision Instruments: Used as precision discs in instruments such as meters, gauges, and analytical equipment due to its precise dimensions and smooth surface.
  6. Power Generation: Used as components for fuel cells and electrolyzers due to its corrosion resistance and compatibility with harsh environments.
  7. Semiconductor Manufacturing: Used as substrates for semiconductor wafers and thin film deposition due to its high purity and stability during processing.
