What sort of material would you choose for low stress fatigue where large numbers of cycles would occur before failure?

Solution

The materials used for low stress fatigue where large number of cycles would occur before failure are such type of materials where edurance limit is not present in the S-N curve for the corresponding material is not present. Such materials may include ductile homogenous single -phase metals and some alloys, low carbon steels, some stanless steels, spheroid graphite cast iron etc.

For example:

Single phase metals are copper and nickel.

Alloys - aluminium alloys like 2014-T6 aluminium, 2024-T6 aluminium, 2024-T3 aluminium etc; copper alloy like Red Brass or Gunmetal etc.
