191g (6.75oz) Pure Cobalt Metal Electrolytic Cathode 99.98416% Element Sample

Description

You will receive 191g ± 3g (6.75oz ± 0.1oz) ultra-high purity
Cobalt
metal cut cathode.
You will receive three pieces similar to the ones in the picture.   Due to variations, you may receive very slightly more or slightly less than 6.75oz.
The amount of corrosion seen in the image is typical of what you will receive.
This cobalt is ethically sourced from Norway.
I do have smaller pieces available.  If 6.75oz is more than you need, message me and I can quote you.  Price will be the same per ounce as this listing.
Pieces can be cut, though not with precision. Because of the crystal structure of the pieces, they can be cut easily with bolt cutters without losing material. Leave a note with your order if you would like this.
The pieces measure
approximately
5/16th (0.31) inches (0.8 cm) in thickness and about 1.25 inches (3 cm) for the length and width.  There is variation between the samples and these dimensions are not exact.  It really is a bunch of broken square pieces that have been matched to be as close to 6.75oz as possible, as the average weight of each piece is 2.25oz.
Cobalt prices have been steadily rising since early 2017 due to increased demand for electric car batteries.
A copy of the COA will be included with every order.

I do my best to ship the same or next business day.  eBay usually overestimates the expected delivery time.
I am happy to combine shipping on orders.  I also offer high purity cadmium, iron, tin, and boron.
Positive feedback is appreciated.  I will always give positive feedback in return.
Combine shipping on multiple items by clicking "Add to Cart" instead of Buy it Now.  Sometimes the shipping calculations can be off, and in the event that you get overcharged for shipping by more than a dollar, I will refund the difference.
