FAQ

Can titanium spring washers directly replace stainless steel components?

Physical replacement is typically possible, but engineering considerations are essential. Titanium's lower elastic modulus (113 GPa versus 200 GPa for steel) affects deflection characteristics and may require design modifications to achieve equivalent clamping forces. Consultation with engineering teams ensures proper performance matching.

Why choose Grade 5 titanium over Grade 2 for spring applications?

Grade 5 (Ti-6Al-4V) provides significantly higher yield strength and better spring characteristics compared to commercially pure Grade 2 titanium. Grade 2's lower strength results in permanent deformation under high loads, while Grade 5 maintains elastic recovery essential for spring function.
