In the construction of a FTN.5/4.5/4/3, etc is it recommended to anneal the PA6-CF? It seems it looses some of it’s impact resistance and flex but temperature resistance increases and also becomes stiffer and slightly more brittle. I’m assuming it’s recommended but just wanted to verify. Thanks!


They are commonly found on amazon and ebay, and are pretty cheap. Usually under 10 bucks
thanks for the response.
