Dear Performance Titanium Group,

On behalf of the 2018-2019 Pennsylvania College of Technology Baja SAE Team, I would like to thank you again for your generous donation from PTG of titanium to our organization. Here is how we used the 6AL-6V-2SN 2.5200″ diameter round stock. So, for our drivetrain, we’ve concluded that titanium is a better choice for this application over aluminum because we realized that in the case of an accident, the titanium survived and experienced less galling on other mating parts. Which increased part life and strength in our drivetrain and suspension because they are both used in the same system where our axle acts as a suspension member.

Compared to steel, 6AL-6V-2SN has a greater benefit to how much lighter it is while keeping the same amount of strength or even greater. When it came to machining it, following the correct speeds and feeds and appropriate cutters/inserts, we were able to produce parts that had finishes we desired, while still maintaining tolerances. Another reason why we like using the titanium PTG supplied us is because the same parts in aluminum in the same application showed stress marks and damage after one race, where the same part made in titanium has survived multiple races and testing without need for replacement. We used the titanium supplied to create a fully titanium universal axle set, which includes axle yokes, output yokes, and rear hub yokes. This helped us achieve 8th in our most recent competition, Baja SAE Rochester.

Thank you again PTG for supplying our team with plenty of titanium which has opened up the opportunity for newer, lighter, and stronger designs for the parts used on our car created by us! On behalf of the 2018-2019 Pennsylvania College of Technology Baja SAE team, thank you for your support!
