Tantalum metal ingot - one troy ounce - .9995 bullion
Tantalum has a high melting point and strength, good ductility, is corrosion resistant, and is highly conductive of electricity and heat. These properties make it useful in the production of capacitors and other electronic components and its superalloys are used in the aerospace, nuclear, and medical industries. Approximately 60% of worldwide tantalum production comes from South America and Australia. Worldwide production in 2012 was only 765 tonnes of tantalum, compared with 2700 tonnes of gold. Please see the below links for more information.
Inscribed on our ingots are the chemical symbol (Ta), purity (99.95%), weight (one troy ounce), and a serial number (this number is unique and will vary). On the reverse is our logo. These ingots are lightly polished though most are not as well polished as the single one pictured. See the group pictures for representative ingots from this batch. As we suggest with all of our metals please keep in a safe place, do not ingest, and keep out of the reach of children.
Each ingot will be shipped with an assay certificate and every shipment will include our velvet logo bag. If you are not completely satisfied with any purchase from us, you have 30 days to return it for a full refund (buyer to pay return shipping). Domestic shipping is free for all orders over $99 (enter code free shipping at checkout). For orders of $99 or under, domestic shipping is $9.95. International shipping is via DHL, FedEx, or USPS international express and costs $45 for shipments up to a pound (9 one ounce ingots or less including packaging materials) and $10 for each additional pound. International customers please be aware that your country may levy import duties and/or VAT taxes on your purchase from us. We have nothing to do with this and cannot pay it for you. If you refuse our package because of this extra cost we will take it back and will refund your order in full once received minus the cost of the return shipping. If you are unsure what these import costs will be please check with your country's customs office.
