I'm looking forward for some manufacturer to come up with titanium chassis for sedans, hope they will make one too.

A Ti chasis is a big no-no for many reasons.

1. Price, a Ti chassis should be done from a solid billet, needs to be machined and machining Ti is really a PITA. So adding the price of machining to the price of raw materials plus the profit of the manufacturer could lead to a sky-high prices (count about paying the same or more than the kit you bought).

2. Ti is a crappy material when it comes to heat transfer. Your engine, to perform at 100% should be heated and the chassis soaks heat too.

3. Ti is very strong, but brittle with some impacts. Your chasis should be tough to tweak, but Ti will be too hard and lacking the elasticity needed for a chasis.

Are there different grades of titanium like aluminum, stainless steel, etc.?

All I know is that titanium differs with their tensil strenght:
6/4 titanium (6% aluminum. 4% vanadium alloy, and 90% titanium) is the strongest; next is 3/2.5 titanium (3% aluminum, 2.5% vanadium alloy, and 94.5% titanium); then the 100% titanium.

In aluminum, the 7000 series is stronger than 6000 series aircraft aluminum.

I got my sources from old mountain bike magazine regarding merlin and litespeed titanium frames.

Thanks

Where to read about alu alloys.
 

Found some time ago this page and I've been searching. May be of interest for someone to know what means all those numbers behind the alloy number.
