BZ 3D 1PC CR10 Plated Copper Heater Block,MK8 Heating Block Upgrade With Silicone Sock,For CR10,Ender 3,Ender 5 Hotend,MK8 Nozzle.(1PC Copper)

The Plated Copper Heater Block are engineered for ultimate high temperature performance. Made from a special high temperature copper-alloy with a softening point of well above 500°C and with much-increased thermal conductivity. In addition to high temperature performance these Heat Block have an advanced nickel based plating, considerably reducing the adhesion This is great for keeping things clean and shiny, but is particularly important at temperatures above 280°C where a silicone sock can't be used. 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 reduce 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 that other nozzles can't handle. These Plated Copper Heat Block and Plated Copper Nozzle are perfect for high temperature applications, while working perfectly with everyday filaments like PLA, ABS and spoolWorks EDGE.
