This is the MK8 style brass nozzle with PTFE coating. The Teflon coating can effectively prevent filament sticking to the nozzle surface, improving print quality by keeping the nozzle clean.
Brass is by far the most common metal used for 3D printer nozzles. This copper-zinc alloy offers great heat transfer at a relatively low cost. However, while these nozzles tend to be inexpensive, brass isn't the most resistant material and is highly vulnerable to wear, so it will need to be replaced from time to time.
Please note that the Teflon coating used on the nozzle is the same as the Teflon coating found on non-stick cookware. While some sellers claim that the Teflon coating is safe up to 300°C, but we at Wondershop value scientific evidence over marketing hype, we do not recommend heating anything that contains Teflon above 260°C.
