Titanium

Titanium fasteners offer strength, low weight, and excellent corrosion resistance.

Titanium fasteners are ideal for marine applications due to their excellent corrosion resistance.  Grade 5 titanium (due to its high aluminum and vanadium material content) is the strongest of all the titanium alloys.  Grade 5 titanium is 60% the weight of 316 stainless steel but is harder and stronger.

Titanium fasteners are popular in aerospace applications due to their strength : weight ratio.
