High-quality Alloy: The composition of TC4 titanium alloy material is Ti-6Al-4V, which belongs to (a+b) type titanium alloy, with good comprehensive mechanical properties and high specific strength. The intensity of TC4: sb=1.High Temperature Resistance: All metal heat heatbreak works well with high temperature filament. No Teflon wear or burn, high temperature resistance up to 450-500 degrees, can better show its performance when matching Capricornus.Conducts Heat Quickly: The V6 heatbreak is made of titanium alloy and copper. Titanium alloy is used to reduce the heat conduction upward from the heating block, while copper is used to accelerate the heat conduction. accelerate the heat conduction. The thermal conductivity of TC4 is about I=7.955W/m·K.Easy to Install: This heatbreak is a direct replacement for your Ender 3 and CR10 3D Printer, and the bayonet design allows screws to be screwed into place for easy removal.Applicable Models: The titanium alloy and copper heatbreak is compatible with Ender 3 V2, Ender 3 Pro, Ender 3 CR10 series 3D printers, the thread size is M6. Specification: Color: coppery Material: titanium alloy, copper Product Size: as shown in the detail picture Package details: 2 x heatbreak Note: Due to manual measurement, the size and weight may have a certain error. Due to the difference between monitors, there may be a slight color difference.
