    To customize your Nb521 niobium alloy powder, please provide the following details:

    1. Purity (Specify the purity level)
    2. Particle Size (Required size range)
    3. Morphology (Spherical, irregular, etc.)
    4. Quantity of the powder you need

    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.

    Its key advantages include an extremely high melting point, superior high-temperature strength and creep resistance, excellent corrosion resistance, and a lower density compared to many other superalloys.

    In AM, Nb521 alloy powder is utilized in processes like Selective Laser Melting (SLM) or Electron Beam Melting (EBM) to layer-by-layer fuse the powder, directly manufacturing complex, high-performance, heat-resistant metal components.

    Particle size and distribution directly affect the powder’s flowability, packing density, and sintering behavior, ultimately determining the performance of the final product (e.g., electrical properties of capacitors, mechanical strength of alloys).

    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. As a professional provider of refractory metals, specialty alloys, spherical powders, and various advanced materials, we serve the research, development, and large-scale industrial production needs of the scientific and industrial sectors.
