From the Titek website:

TiTek Speed (long) Lug Nuts are made of 7075 Aluminum Alloy. They are one of the highest strength aluminum alloys, with a tensile strength of 83,000 psi. Because of its strength to weight ratio, they are commonly used for aircraft and aerospace technologies. Constructed for your vehicle, TiTek Lug nuts come in a series of matte colors such as black, red, blue, and gold.


So.... no idea. I will say that I have used other lug nuts that were painted instead of anodized and the paint flaked wherever the socket touched it, these didnt do that
