• Heater block and Nozzle is made from copper alloy. This copper-alloy is very temperature resilient, and will not start to soften or anneal until way beyond 500°C, making it perfect for the high-temperature printing. In addition to high temperature performance this Block have an advanced nickel based plating
• Heater block Size: 23x16x11.5mm, With OD 3mm cartridge Hole for temperature sensor; Heatbreak is made from Titanium TC4 material to provide excellent thermal isolation between heater and cooling 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 will also slightly increase your heat-up times, and can provide Highter temperature control.
• We upgrade the aluminum heatsink with more cutouts, it has better heat dissipation to make your printing more smoothly
• This kit is used for 1.75mm filament, and This pack is NOT including heater tube and thermistor, please know before ordering.
