Updated High Temperature CR 10 Plated Copper Heater Block for MK8 Extruder Creality All Metal Hotend Ender 3s V2 3 Pro 5 CR10 S4 S5 3D Printer (Copper)

Material: Copper alloy; It is machined with very high precision and high quality, this block is upgraded by machining an extra 3.1mm hole for high termperature sensor cartridge use Compatible with Creality ALL Metal Hotend Ender 3s Ender 3 pro Ender 5 Pro CR10 S4 S5 3D Printer and MK8 MK9 extruder 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 tighter temperature control. 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 Size: 20x20x10mm, package: 1piece plated copper CR10 block
