ISCASELLE/SERFAS PLUMA TITANIUM SHELL SADDLE
The Pluma takes an interest in Titanium to the limit by making the shell of a single piece of thin wall sheet, and using hollow Ti tubes for the rail assembly. The shell is stamped to the required shape with a 1/16" metal edge folded back on itself around the perimeter for safety against cuts and to add structure through thickness at the edge. We measured the folded thickness at .91mm which means that the single wall thickness is in the region of .5mm thick. The shell is made of Grade 6 Titanium plate. Grade 6 is not discussed specifically in our metallurgy section, because its use in the bike industry is uncommon. It is an Alpha phase alloy available in a standard grade or extra low interstitial (ELI) grade. The standard grade is used for gas turbine engine casings and rings operated at high temperature.
