Use an aluminum nozzle made out of a high-strength aluminum alloy, such as 2024 or 7075. This should lighten the nozzle as well as improve the thermal conductivity of the nozzle. (Depending upon the alloy, the thermal conductivity, can be more than twice that of brass and an aluminum nozzle should be around 1/3rd the weight of a brass nozzle.)
However, breathing its dust or vapors, as formed when machining or welding, will eventually cause serious lung damage. Beryllium compounds are known human carcinogens when inhaled.
