Presing and sintering, primarily multi-level parts made from carbong steel, nikel steel and copper infiltrated. About 70% of our parts go into new cars. If you have bought a new car in recent years, you have parts in it we have made. If you drive a F150, in the tailgate, there are 8 parts we make, for the torsion bar system.
My gut feeling, as I have said, is the steel is basically re-melted, imported from wherever, scrap that could have anything in it., hence the variability, with some superb and others, bleh!
If the thunder don't get you, the lightning will.
