The Bi-Metal High Temperature Throat Tube (also known as Bi-Metal Heat Break) is a premium upgrade for standard V6-style hotends. It combines Titanium Alloy on the hot side with Copper Alloy on the cold side, providing excellent thermal isolation while maintaining superior heat dissipation.
Key Features:
- Bi-Metal Construction: Titanium alloy (low thermal conductivity) prevents heat creep, while copper alloy (high thermal conductivity) efficiently pulls heat away from the heat sink area.
- High Temperature Resistance: Supports printing temperatures well above 260–300°C, making it ideal for engineering filaments like ABS, ASA, PC, Nylon, and PEEK.
- All-Metal Design: Eliminates PTFE tube in the heat zone, preventing degradation, toxic fumes, and clogs at high temperatures.
- Compatibility: Perfect fit for E3D V6, J-Head, Creality Ender 3 series, CR-10, and most V6-style hotends (threaded version).
- Smooth Filament Path: Precision machined for smooth 1.75mm filament feeding and reduced friction.
- Durable & Reliable: Significantly improves retraction performance, flow consistency, and overall hotend stability.
This bi-metal throat is an essential upgrade for users experiencing heat creep, PTFE tube wear, or wanting to push their printer to higher temperatures without reliability issues. It transforms a standard hotend into a true high-temperature all-metal setup.
