Hello
Well, there are many reasons for combining a soft and a hard material.
One of them it is that you prefer to preserve in better shape one of
them, lansting more, this will also be the more expensive part. The
soft part will be the one collecting the damage and will have a short
life. Then when you need a service you just change the soft part and
you have your mechanism like new.
Sorry, I think that explanation was to complex for my english
if you use 2 metals after some time you will have to change
both pieces, in metal + soft you change one only.
Bye.
