    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.

    It is a high-purity niobium (Nb) powder specifically processed to have an extremely low oxygen content, typically below 500 ppm (parts per million). This is crucial for applications where oxygen impurities would degrade performance.

    Oxygen impurities can embrittle niobium, reduce its electrical conductivity, and lower its superconducting performance. Low oxygen is essential for maintaining ductility, high thermal/electrical conductivity, and other key properties.

    It must be stored in a sealed, airtight container under an inert gas atmosphere (like argon) to prevent moisture and air exposure. Handling should be done in gloveboxes to minimize oxygen pickup.

    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.
