Most hi-performance two-stroke cylinders we use are aluminum with a
NiCom plated bore.

Pistons are forged aluminum.

Does anyone know some good materials too use in making of racing cylinders
for two strokes?

The problem is that alcohol and nitro mixes create unusual high
temperatures.
It must altso tolerate punishing high revs' (20,000 rpm )

And the piston?

Titanium perhaps?
