Valve Seat Material Grade

[RicBB]

I'm hoping someone can help me with this. I am trying to track down a material spec for valve seat inserts to fit a diesel engine with and an aluminium head.

I appreciate that this is rather vague but any nudge in the correct direction will be appreciated.

Thanks,
Rich

I don't know what exactly they make 'em out of , but i know they are sintered, so it'll be some complex combination of powders.
