    Medical Grade Tantalum Wire

    Tantalum can be made into ultra-thin wires, thinner than human hair. They are good for surgeries because they can be sterilized, don't irritate, and are strong, but hard to knot.

    In Hot Furnaces

    Tantalum wire is used in super-hot furnaces. It doesn't melt even at extreme temperatures. This makes it great for heating elements in these furnaces.

    In Vacuum Electronics

    Tantalum wire is also used in electronics that work in vacuums, like some tubes. It's good at conducting electricity and can release electrons, which is necessary for these devices.


    Manufacturing Processes for Tantalum Wire

    The manufacturing process of tantalum wire involves several key steps to ensure its quality and precision. Here's a breakdown of the process, based on Powder Metallurgy.

    Manufacturing Processes for Tantalum Wire

    Advanced Powder Production

    AEM Metal uses advanced chemical reduction to create ultra-pure, uniform metal powders. This process is key for high-quality metal products.

    Mixing Alloys

    Our alloy mixing process is characterized by meticulous precision. This creates alloys with unmatched performance and reliability.

    Precision Pressing and Shaping

    Using state-of-the-art pressing techniques, we mold our metal powders into desired shapes. Our technology excels in producing complex geometries with high precision.

    Sintering Process

    Our sintering process employs advanced technology. It bonds powder grains effectively, creating dense and robust sinter blocks. This step is crucial for the durability of our products.


    The tantalum is shaped by rotating and hammering. This step is crucial for initially forming the metal into a more workable shape, preparing it for further refinement.

    Intermediate Annealing:

    Annealing is a heating process that makes the metal more bendable and less hard. It helps make tantalum easier to shape into wire and removes any inner flaws or stress.


    After annealing, the tantalum is pulled through different sized molds to make it thinner. This process, called drawing, is repeated several times with smaller molds each time to get the wire to the right thickness.

    Final Annealing:

    After the tantalum is made into wire, it goes through one last heating process. This relaxes the wire and makes it stronger and more flexible. This final step is important to make sure the wire is of good quality.

    Final Product Inspection

    Inspect the final Tantalum wire, including dimensional measurements, surface inspection, chemical composition analysis, etc. This ensures that the final product meets specifications.

    Quality Control: Tantalum Wire Testing

    Quality control is key in making tantalum wire. It makes sure the wire works well for its specific use.

    Tensile Strength Test:

    This checks if the wire is strong. We pull the wire until it breaks to see how much force it can take.

    Bend Test:

    Repeatedly bend the wire to check how many times it can bend without breaking. This tells us about its flexibility and strength.

    Diameter Check:

    This makes sure the wire is not too thick or thin. It's important for jobs where size matters.

    Chemical Test:

    This looks at what the wire is made of. It checks if the wire won't rust and will conduct electricity well.

    Surface Check:

    This looks for any rough spots or problems on the wire's surface. It's important for uses where the wire needs to be smooth.
