    To customize your low-oxygen tantalum powder, please provide the following details:

    1. Purity
    2. Particle Size
    3. Quantity of the powder you need
    4. Applications (We can also make recommendations based on your specific needs.）

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

    We carry a wide variety of tantalum and tantalum 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 tantalum 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.

    Levels vary by application. For high-end sputtering targets and additive manufacturing, oxygen is typically required to be <100 ppm. For high-performance capacitors and general PM parts, a level of 200-500 ppm is considered low-oxygen. Regular sodium-reduced powder can have oxygen content exceeding 1000 ppm.

    It is critical. Low oxygen content significantly reduces the tendency for hot cracking during printing and improves the density and mechanical properties of the printed part, especially ductility and fatigue strength. This enables the printing of complex-shaped, high-integrity tantalum components (e.g., medical implants).

    Targets made from low-oxygen powder have a more uniform and finer grain structure and higher purity. This helps reduce particle contamination and arcing during sputtering, resulting in the deposition of higher quality, lower defect thin films, greatly improving the yield and performance of semiconductor devices.

    Shanghai Yuepeng Tech, established in 2022 in Shanghai, China, is a specialized supplier and manufacturer of tantalum and tantalum 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.
