Any information anyone has is appreciated. I'm interested in metal apex seals like the ones Powerhouse Engineering sell. What makes the nodular grain so much stronger than the flake type? Who sells the flake type material apex seal if anyone?

kryptonite.

 

the mazda seals are cast iron with a laser chilled friction surface

Hey, and I thought Lasers heated things up, like in the Bond movies?



Seriously, can you explain this technology (I'll put my serious face on now)

 

"a metal seal of special cast iron as base metal, chilled by electron beam, began to be mostly used against the porous chrome-plated inner surface of the rotor housing..."

Wow, Mike, you're da man!



Now if you actually understood that, then I'd be really impressed!



So what they're saying is that the factory seals are a sort of cryogenically hardened? We have a firm here in Perth doing that- I think they use liquid Nitrogen or similar rather than fancy electron beams!
