The tensile and yield strengths of Grade 2 and Grade 5 titanium are two of the most noticeable differences between them when their mechanical properties are compared. Grade 5 Titanium is a lot stronger than Grade 2. Usually, Grade 5 Titanium can handle a pull force of 895–930 MPa and a push force of 828–862 MPa. Grade 2 Titanium, on the other hand, has a lower tensile strength of about 345–485 MPa and a yield strength of 275–410 MPa. Grade 5 titanium is better for uses that need to support a lot of weight and not bend because of these differences in strength. Topak's Grade 5 Titanium goods are made to meet or go beyond these strength standards so they can be used in tough situations and always work right.
Hardness and ductility differences
Grade 2 and Grade 5 titanium also have very different levels of hardness and flexibility. Grade 5 Titanium is harder than Grade 2 Titanium. Grade 5's hardness is between 36 and 39 on the Rockwell C scale, and Grade 2's is 80 on the Rockwell B scale. The greater hardness of Grade 5 titanium makes it more durable and resistant to wear. When it comes to flexibility, Grade 2 Titanium generally has higher elongation values than Grade 5 Titanium. Grade 2's is usually around 20–30%, while Grade 5's is about 10–15%. Grade 5 titanium has better strength and hardness but lower ductility. Topak sells many different titanium goods for a variety of uses. They offer Grade 5 titanium, which is very strong, and Grade 2 titanium, which is more ductile, to meet the needs of all their customers.
Fatigue resistance and fracture toughness
Weakness resistance and break strength are vital properties for numerous designing applications, and Review 5 Titanium outflanks Review 2 in these perspectives. Review 5 Titanium shows predominant weakness resistance, with a weariness quality of around 510 MPa at 10^7 cycles, compared to Review 2 Titanium's weakness quality of approximately 300 MPa at the same number of cycles. This improved weariness resistance makes Review 5 Titanium perfect for components subjected to cyclic stacking, such as aviation structures and restorative inserts.
