Tantalum Rod and Tantalum Bar

Tantalum Rod is made from high-purity tantalum metal, known for its excellent corrosion resistance, high melting point (around 3000℃), and outstanding oxidation resistance. It is commonly used to produce high-performance capacitors, transistors, chemical reactors, and high-temperature components. Tantalum Bar has a square or rectangular cross-section. Shanghai Yuepeng can provide custom sizes, shapes, and compositions to meet specific demands.

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

    To customize your tantalum rod or tantalum bar, please provide the following details:

    1. Diameter x Length (for rods)
    2. Length x Width x Height (for bars)
    3. Quantity of the rods or bars you need
    4. 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.

    Tantalum is soft and ductile but work-hardens easily and can gall. Use sharp, positive-rake carbide or diamond tools, employ low speeds with high feed rates, and apply ample coolant (e.g., oil-based emulsion) to dissipate heat and prevent galling.

    The most common standard is ASTM B365, which specifies requirements for chemical composition, mechanical properties, and dimensional tolerances of tantalum and tantalum alloy rod, bar, and wire for electronic and chemical applications.

    Common grades include: R05200 (unalloyed, 99.95% purity), R05400 (unalloyed, 99.95% purity with lower interstitial elements), and R05255 (Ta-W alloy, 90% Ta & 10% W for higher strength).

    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.
