<t>It may not be used because of the reason you mentioned but even if it had a higher melting point I would still had the same problem which I had earlier. <br/> Polymers in general have higher coefficient of thermal expansion than metals so while heating the piston gets stuck in the cylinder or is ...

<t>I am working on an alpha type Stirling engine for which I am using<br/> aluminium cylinders and teflon pistons. While testing I realized that<br/> teflon expands more than aluminium and thus it gets stuck when heated<br/> , restricting its motion. Now I am thinking of replacing the teflon<br/> pi...
