Nickel-plated copper nozzles D3,  DHB 22.5, 24, 33

As they conduct heat better, copper nozzles in diameter 3mm harness the larger heating zone of the Starlex DHB Eco-system to provide high feed rates and work with high temperature materials. 

To resist better with standard materials, it has been plated with hardened nickel. 

Hardened nozzles adapted for abrasive material in diameter 2.5mm to keep the high thermal conductivity are also available.

When Swiss high end machining quality is added, you get the best deal ever.

At present, those nozzles are available in the standard 0.4 and the larger 0.8 mm diameters.
