Tungsten metal ingot - one troy ounce - .9995 bullion Tungsten (aka Wolfram) has the highest melting point and tensile strength of any pure metal. Tungsten can be alloyed with a wide array of metals to improve their properties. It is used in the steel, construction, petroleum, military, chemical, jewelry, nuclear, medical and electronics industries. Approximately 80% of worldwide production comes from China which means it could be subject to supply disruptions. It ranks second on the 2012 British Geologic Survey's "risk list". Please see the below links for more information. Inscribed on our ingots are the chemical symbol (W), 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, can be a little rough on the edges with occasional small edge chips and edge peels, and not all are as well polished as the single one pictured. Like with all of our products, these ingots were designed and manufactured with careful attention to weight and purity, both of which have been checked and rechecked and are guaranteed by us. 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 $199 (enter code free shipping at checkout). For orders of $199 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. http://en.wikipedia.org/wiki/Tungsten http://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust https://nora.nerc.ac.uk/id/eprint/513472/1/Risk_List_2015_FINAL.pdf
