Hi Robert
My name is Sohrab and I have been doing some research on the
Stirling engine.
I have decided to build one which is approximately 200 watts.
I would appreciate if you could please tell me what kind of
materials I can use to build cylinder and pistons specifically, what
materials are the best. Also I was wondering If you could explain
why the cylinder should be flat and wide
Thank you for your time and consideration.

Materials for Stirling engine?
Sohrab:
It would help if you could tell us more about the engine you plan to build. You ask why the the cylinder should be flat and wide. Are you considering copying the design of the "Coffee Cup" engine? The "Coffee Cup" engine is an LTD design and is not adaptable to a power producing machine.
Let me sugguest that you review all of the prior posts in the Power-producing Stirling engines bboard to get a better understanding of what is involved in the design and construction of a 200W machine.

Dear William
Thank you for you replay one of my friend has made the design I am not coping anything. I found out from one your co-worker that the cylinders must be wide and flat without explaining the reason. I want to run this Stirling engine with hot water this machine is a alpha type and has got two cylinders.
I would appreciate if you could please tell me what the best materials are for cylinders and pistons. Finally I just want to know what kind of characteristic the materials need to have for cylinders and pistons.
Thank you for your time and consideration.

Response to materials for Stirling engine
Using hot water as the heat source will NOT permit generating 200 W. If you could provide the design drawing(s) of the proposed engine we might be able to be of more assistance.
For heat source temperatures less the 212 F or 100 C you can use glass & graphite for the cylinder and piston. For higher temperatures steel, or brass cylinders and brass or graphite pistons respectively.
Attempting to build a 200W SE without prior engine building experience is an iffy business.

Hi Robert
this is Sohrab again. Thank you so much for your information you have helped me a lot.
Another question is that what sort of material we can use to seal it. I would appreciate if you could please tell me.
Take care.
