Im at university and am doing a materials project. The part I have selected is a front brake caliper adaptor bracket for oversized discs.

I know aluminum is normally used but need to make sure it’s the best or find a better material.

The question is which are the best materials to use and why? Price is not important, as there is not a lot of material needed so per weight material is not that expensive.

What factors are the most important? Young’s modulus, shear modulus, tensile strength, compressive strength, fatigue toughness? Any others? What is an endurance limit I would have thought it was similar as fatigue toughness?

All the carbon steels seen to be suitable, nickel based super alloys, titanium alloy, carbon fiber in epoxy matrix, stainless steel, aluminum (7000 series??) al/silicon carbide composite. How should I decide which is best for the product.

I have ces edupak so can plot graphs of the different properties but am not sure which will be the best properties to plot to find the best material?

Also manufacturing is important and I know so material needs to be fairly easily turned into final product. Guess cnc would be used on most materials.
