Tantalum Wire

Tantalum wire is a high-performance material made from tantalum metal, known for its high melting point, corrosion resistance, and good electrical conductivity. It is widely used in the electronics industry (e.g., capacitor production), medical devices (e.g., implants), and high-temperature industrial applications due to its excellent chemical stability and mechanical properties.

    We will check and get back to you in 24 hours.

    To customize your tantalum wire, please provide the following details:

    1. Diameter x Length
    2. Purity of the material
    3. Form (straight or coiled form)
    4. Quantity of the wire you need
    5. 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 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 diameter range is wide, from very fine 0.1mm (or even finer) for precision electronics to 2.0mm or thicker for industrial and additive manufacturing applications. The most common range in the capacitor industry is between 0.2mm and 0.6mm.

    Under vacuum or inert gas protection, tantalum wire can be used at temperatures above 2200℃, often as heating elements. However, in air, it begins to oxidize rapidly at temperatures above approximately 250℃, so it must be used in a vacuum or inert atmosphere.

    Common surface treatments include:

    • Pickling (removes surface oxide)
    • Electropolishing (produces an ultra-smooth surface, common for medical use)
    • Bright Annealing (produces a clean, smooth surface in vacuum/inert gas)

    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.
