Specialneeds Posted January 15, 2020 Share Posted January 15, 2020 Tungsten is very hard. One of the most hard materials on earth. However... hard is equal to brittle in this case. Anyone ever break a tungsten sleeve? Granted it has good tensile strength.. Just curious how well these are living. Sure it adds some dwell due to reducing the FPS of slide during initial movement. Though, it has me wondering about real world longevity. Any insight or opinions welcome. Thank you Link to comment Share on other sites More sharing options...
RIIID Posted January 15, 2020 Share Posted January 15, 2020 There are different tungsten alloys, tungsten carbide is more brittle and harder to machine than tungsten alloyed with say steel which isn't as brittle and is easier to machine. The bigger concern with a tungsten sleeve is wear resistance, if there is too much wear on the sleeve or slide accuracy will be effected.

Stickman301 Posted January 21, 2020 Share Posted January 21, 2020 I’ve never heard of anyone breaking the sleeve. They do shoot nice but it’s an expensive option. Hybrid barrel accomplished same principle in different fashion. Link to comment Share on other sites More sharing options...
