• Bimetal Heatbreak Throat Tube - Using TC4 titanium alloy and copper two kinds of metal processing, titanium alloy has good thermal insulation, copper to help heat dissipation.For a long time of printing has an obvious role in improving the quality of printing.
• Nickel Copper plated nozzle 0.4mm - It has smooth inner hole and outer surface, which is more smooth and stable for material extrusion. It can be applied to all kinds of materials. The maximum working temperature is 500°.
• Nickel plated copper Heater block - Copper has more than 3x the thermal conductivity of brass, and the copper alloy we use has been hardened and treated to reduce the oxidation that occurs in copper at high temperatures. The higher thermal conductivity also slightly increase your heat-up times, and provide highter temperature control,Reach up to 500°C, making it perfect for the high-temperature offer FREE shipping on all orders!
