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 allows us to create complex shapes and designs for specialized applications. Shanghai Yuepeng 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
  • Defense and Aerospace
  • Medical Devices

    • 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.

    To customize your niobium custom parts, please provide the following details:

    1. Dimensions (length, width, height, and other parameters of the parts)
    2. Shape/Design (providing details on the part’s shape)
    3. Tolerances (Specify the allowable deviations in dimensions)
    4. Purity of the material
    5. Quantity of the products you need
    6. Alternatively, you can provide a drawing with your specifications.

    Once we have these details, we can provide you with a quote within 24 hours.

    We carry a wide variety of niobium and niobium alloy products in stock, and for these, there is generally no minimum order requirement. However, for custom orders, we typically set a minimum order value of $200. The lead time for stock items is usually 1-2 weeks, while custom orders usually take 3-4 weeks, depending on the specifics of the order.

    DFARS (Defense Federal Acquisition Regulation Supplement) compliance is primarily concerned with the sourcing of materials for defense-related applications in the United States. According to DFARS, certain materials used in defense must be sourced from the United States or qualifying countries.

    If you have specific niobium materials that are subject to DFARS, please let us know in advance and we will confirm.

    At Shanghai Yuepeng Tech, we take this responsibility seriously. We adhere to all applicable laws and regulations, including Section 1502 of the Dodd-Frank Act. Our company operates with a strict code of ethics and is committed to only partnering with suppliers who share our dedication to responsible sourcing. We support the initiatives and programs aimed at promoting “conflict-free” supply chains and work diligently to ensure that our products meet these standards.

    Key processes include: CNC machining (turning, milling, drilling), Wire EDM (Electrical Discharge Machining), Electron Beam Welding (EBW), laser welding, stamping, deep drawing, and surface treatment (e.g., polishing, pickling).

    Reputable suppliers provide full-process quality reports, including Material Test Certificates (MTC) for raw material, dimensional inspection reports, surface finish checks, and non-destructive testing (e.g., ultrasonic) to ensure parts meet specifications.

    Shanghai Yuepeng Tech, established in 2022 in Shanghai, China, is a specialized supplier and manufacturer of niobium and niobium alloys. With extensive expertise in supply and export, we offer competitive pricing and customized solutions tailored to specific requirements, ensuring outstanding quality and customer satisfaction.
