    To customize your tantalum tungsten 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 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.

    The most common grades are Ta-2.5W and Ta-10W. Ta-2.5W offers improved strength while maintaining excellent corrosion resistance and is widely used in chemical equipment. Ta-10W provides very high strength and high-temperature capability, often used in more demanding fields like aerospace and defense.

    Ta-10W is one of the strongest and hardest grades in the tantalum tungsten alloy family. It retains good corrosion resistance, but its extremely high strength at elevated temperatures and superior creep resistance make it the material of choice for ultra-high temperature, high-stress environments, such as aerospace propulsion systems and certain specialized chemical processes.

    Using Electron Beam Melting (EBM) technology is the most suitable method for 3D printing. The EBM process operates in a vacuum and at elevated bed temperatures, which effectively prevents cracking and produces complex-shaped parts with high density and properties close to wrought material, such as conformal cooling channels in rocket engines or high-temperature fixtures.

    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.
