The unique cooling block makes a thermal tube unnecessary. By eliminating a separate heat conductor in the cooling block, faster heat dissipation is achieved. The thermal insulation is made from a titanium alloy of grade 5 to ensure excellent thermal insulation between the heating element and the cooling block. Titanium is an extremely strong material and offers nearly three times lower thermal conductivity than stainless steel, creating a defined melting zone. Suitable for: Creality CR-10, Creality CR10S, CR10S4 and CR10S5, Creality CR-10 Mini, Creality CR-20 and Creality CR-20 Pro, Ender 2, Ender 3, TronXY X5S, Trevo Tornado.
