Features All metal material: made of Ti alloy and copper materials, high temperature resistant, constant heating and reduction of material blockages. Good heat insulation: the bimetal heatbreak with a rated temperature of 500 °C can melt the consumables faster with less heat loss. Fast heat dissipation: can quickly dissipate the generated heat, provide a good heat dissipation effect and be safe to use. [5 pieces in 1 set] Includes 5 pieces bimetal heatbreaks for 3D printers in sufficient quantity, which can be used and replaced at any time. Appropriate structure: these heatbreaks consist of 2 parts, 2 components with different thermal conductivity, with firm fixation.
