abrasion resistance
(OP)
Can anyone tell me what physical factors play a role in abrasion resistance? I would think that hardness would play the most significant role, but is it the only deciding factor?
I guess, maybe a low thermal conductivity to keep the material from heating up, and softening. Although, I don't know how practical this problem might be.
My application is use in a screw conveyor, to remove/move wood shavings and ash.
Does anyone have any other ideas?
Cheers

RE: abrasion resistance
Actually when parts heat up often you want high thermal conductivity so that you dont get hot spots and localized melting. Also high thermal conductivity allows cooling systems to work well.
For your application I think that a cast iron part may work very well.
