What are the different materials used in a spring shock absorber?

[taureau20]

I am to design a shock absorber for my project. Pl tell me what material the various components would be made of. Just gimme any rough idea you would have or just make a wild guess Anything! I just need a start and then I will take it from there.

I have designed the thing on Solidworks but do not know what material to apply to various parts. I have labelled all d parts in following diagram. (I have already selected the material for spring so you may omit that one.) See the exploded view of the shock absorber here:
