Q: How does Aluminum 7075 compare to titanium grade 5?
A: Aluminum 7075 can be tempered to many different strengths. The strongest being T6 which not only offers the highest strength. The primary drawback being that it also has low fracture toughness.
Aluminum 7075-T6 bolts offer more strength than grade 2 titanium, but less than that of grade 5 titanium bolts. The most unique feature of Aluminum 7075 bolts is that they have very low density which gives them higher strength to weight ratio than that of titanium grade 2 and a similar strength to weight ratio to titanium grade 5.
