  Paul and Bill,
 Titanium may be better in regard to expansion rates but doesn't wear too
 well without nitrite surfacing, I'm let to believe.

The more I think about this idea the better I like it.

The steel sheet could be heat treated 4130 and the aluminum cladding
dead soft 1100.

For a rotor housing you might be able to explosively form the steel
into the trochoid
shape from round tube while simultaneously bonding it to the aluminum.

This could be a very low cost manufacturing method if automated. Could also
be a cost breakthrough in building aluminum rotary engine. I am
going to continue to look into this.

   Theres an outfit up in Sequim WA that makes deta plate so I may
splash in the bay there on my next trip up to the San Juan's and
check them out.

Ken all we need is a thin cladding of aluminum on say .049 4130 steel sheet.
Just enough aluminum to furnaces braze to a Mazda cast aluminum end housing.

We will surface grind and hone the steel after the clad material is furnaces
brazed to the end housing. Maybe chrome plate it after that.

Jim, can we buy the casting from you without the coatings?
