WebThere are two main nozzle materials used in commercial high power rocket motors: graphite (reusable many many times) and glass reinforced molded phenolic (single use). The phenolic nozzles are ablative, just like the larger nozzles. Interestingly, while commonly listed as ablative, graphite isn't actually ablative. WebGraphite is vastly easier to machine. You do need to be very careful about dust collection, though, as graphite dust is conductive and can wreck havoc with anything electrical. The biggest problem with metal nozzles is finding some place that will allow you to launch with them. (Most sites prohibit the use of metal nozzles.) level 2 Op · 3 yr. ago
