BROZZL Creality CR / Ender Bi-Metal Heatbreak, 1 Pc

The BROZZL Bi-Metal Heatbreak consists of two components with different thermal conductivity: copper alloy and titanium alloy. While the titanium alloy reduces upward heat conduction, the copper accelerates downward heat dissipation. It allows you to print at a temperature of up to 500 °C and effectively prevents the filament path from clogging thanks to its smooth inner wall.

Key Features of the BROZZL Bi-Metal Heatbreak

• Consists of a copper alloy and titanium alloy
• More wear-resistant than a stainless steel heatbreak
• For smoother printing
• Very smooth inner wall
• Reduces heat creep
• Enlarged melting zone
• Up to 500 °C printing temperature

How does a bi-metal heatbreak work?

The heatbreak is considered the connecting part between the “hot” end and the “cold” end of the hotend and is used to form a transition area between the molten material and the solid filament that is fed to the nozzle.

If this precise transition area is not given, the filament tends to soften prematurely and eventually block the filament path. The result is heat creep.

Most heatbreaks are made of metal with a PTFE tube inside. This tube thermally insulates the filament before it reaches the nozzle. The PTFE lined heatbreak is well suited for PLA prints as they do not require high temperatures. However, an all-metal heatbreak allows you to print at higher temperatures without worrying about the PTFE tubing or dangerous fumes.

A bi-metal heatbreak not only improves on the fundamental problems that a PTFE tube hotend has, but it also has advantages that an all-metal stainless steel heatbreak can’t match.
