Aluminum (Al)

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 therefore among our largest ingots along with scandium and magnesium), 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 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.
