This is MK8 style nozzle, it is made from
a 360 brass base material and plated with TwinClad XT coating. TwinClad XT is a
nickel composite coating designed for very low friction. It offers one of the
lowest coefficient of friction, better then nickel with PTFE co-deposit. This
coating is also very hard and abrasion resistant. If you are working with
abrasive Carbon Fiber, Stainless Steel, wood filled or any other metal filled
filaments, this will greatly improve the life of your nozzle.
