Niobium Custom Parts Machining Services

Niobium Custom Parts require precision machining to meet strict tolerances and performance standards. The machining process involves cutting, shaping, and finishing. The niobium and its alloys’ high ductility allow us to create complex shapes and designs for specialized applications. HM can offer common machining services as follows:

  • CNC Machining: Precision CNC milling and turning to create complex shapes and intricate features.
  • Wire EDM: Used for cutting delicate and intricate parts with high precision.
  • Surface Grinding: To achieve smooth, flat, and precise surfaces on niobium parts.
  • Tapping ＆ Threading: This is used to produce threaded holes or custom threads in niobium parts.
  • Electropolishing: Enhancing the surface finish and corrosion resistance of the final parts.

Niobium Custom Parts Applications

Niobium Custom Parts have excellent high-temperature resistance, corrosion resistance, and electrical conductivity, and are widely used in the following fields:

  • Aerospace
  • Electronic Industry
  • Medical Field
  • Nuclear Energy Industry
  • Chemical Industry

Niobium Custom Parts Packaging

The Niobium Custom Parts are carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
