These high-grade Titanium Heat Breaks are an upgrade to the stainless steel Heat Breaks that come as standard with E3D V6 HotEnds.
Since V5, the manufacturing processes for all E3D HeatBreaks has been overhauled to achieve a better internal surface finish than ever before. The improved internal surface finish helps to reduce extrusion force and improve reliability on retractions. They are capable of reliable high temperature performance for many years, but are somewhat delicate due to their fine machining
These special HeatBreaks are additionally made from Grade 5 Titanium. This material is exceptionally strong and has lower thermal conductivity than stainless steel, allowing you to keep the cold side of your HotEnd even colder. This creates a more sharply-defined meltzone within the hot side, creating greater extrusion control.
The increased strength of these breaks means that they are also much less likely to crack or snap, either while hot-tightening or on the occasional accidental collision with a printed part or printer bed.
