Aluminum metal ingot - one troy ounce - .9997 bullion

 

Unlike many of the metals we initially concentrated on due to their rarity, aluminum is the most abundant metal in the earth's crust and the third most abundant element overall, estimated to make up 8% of our earth's crust by mass. It is of low density (and our largest ingot just edging out scandium), high ductility, and is very corrosion resistant. It is also a good electrical and thermal conductor and has superconducting properties. It's industrial uses are numerous and diverse from aluminum cans and foil to transmission lines and from airplanes and spacecraft to solid rocket fuel. Estimated annual production in 2012 was around 42 million tonnes. It sits near the bottom of the 2015 British Geologic Survey's Risk List, but still made the list given it's great industrial importance despite its equally great abundance.

Inscribed on our ingots are the chemical symbol (Al), purity (99.97%), 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. 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 now via USPS international priority 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.
