Zinc metal ingot - one troy ounce - .9999 bullion


Though credit for its discovery was awarded to German chemist Andreas Sigismund Marggraf for discovering its pure metallic form in 1746, zinc has been used in brass (an alloy of copper and zinc) since about the 10th century BC in the Judea Province and about 300 years later in Ancient Greece. Zinc is a hard, silvery-white, corrosion resistant metal with a relatively low melting point of 787 °F. It is used primarily in the galvanization of iron which is a corrosion resistant zinc plating. Alloys including bronze make up the bulk of its other uses. Pennies in this country have been made with 97.5% zinc with a thin copper coating since 1982. Worldwide annual production is about 13 million tonnes, exceeded only by the other base metals iron, aluminum and copper.

Inscribed on our ingots are the chemical symbol (Zn), purity (99.99%), 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, similar to the one pictured. There can be tiny edge dings, light surface scratches, and other small imperfections. As always, weight and purity are guaranteed by Rare World Metals Mint. Handling our zing ingots is considered safe but ingestion of zinc can be toxic or fatal as in one reported case of ingestion of 425 copper coated zinc pennies, so eating our ingots is always bad idea and we actively discourage such activity. It doesn't seem like we should have to mention such things but this is America -- land of the free to be overtly stupid, injure themselves and still sue. As we suggest with all of our metals please keep them intact 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 with our velvet logo bag for storage. 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.
