Feature: 1. Superior Durability: Designed with higher hardness and wear resistant compared to standard throat tubes. The dual metal branch design combines ti alloy for the front end and copper alloy for the back end, offering excellent heat insulation and faster heat dissipation. 2. Excellent Thermal Insulation: Ti alloy reduces heat transfer to the heating location, while copper aids in heat dissipation to accelerate thermal conduction. High overall heat insulation performance, temperature resistant, wear resistant, high hardness, and long lifespan. 3. Enhanced Accuracy: Special internal processing results in a smoother appearance without burrs, reducing backflow resistant and achieving higher printing accuracy and finer details. 4. Increased Printing Efficiency: Bi metal melting consumables rated at 450℃ heat up quicker and have 60% less thermal conductivity than standard insulation plates, effectively reducing heat loss and improving printing efficiency. 5. Applicable Model: Compatible with for K1, K1 MAXIMUM, for Ender3 V3 KE, for Ender3 S1 and other models, offering optimal heat insulation properties for optimal 3D printing performance. Specification: Item Type: Bi Metal Heat Break Material: Ti Alloy, Copper Size: M6 x 19mm Temperature Resistant: 450℃ to 500℃ 1. Compared to regular heatbreak, it has higher hardness and more wear resistant. 2. Internally treated with special process, smoother interior with no burrs, lower backdraft resistant, higher printing accuracy and finer finish. 3. Dual metal heatbreak with split design, front end made of ti alloy, back end made of copper alloy, strong thermal resistant and faster heat dissipation. . Package List: 2 x Bi Metal Heat Break
