Brass, the most commonly used material for 3D printer nozzles, is a good compromise. It’s easy to machine, has good thermal conductivity and is kind of durable.
But we at Imark Industries make no compromises. Our special Titanium Molybdenum alloy is used in professional, high volume, injection molding nozzles. It allows for optimal durability and optimal thermal conductivity. Nozzles made out of our alloy are almost as hard as hardened steel nozzles while having a better thermal conductivity than brass. Our special surface treatments allow for an even harder and wear resistant surface.
During our trials, we investigated multiple different alloys before setteling on this specific one due to it’s good balance between hardness, thermal conductivity and machinability.
