thermal coefficient of expansion
thermal coefficient of expansion
(OP)
Does anyone know of or has anyone seen a poster size reference chart that has among other things, the thermal coefficient of expansion for various materials? I believe there are also graphical representations of the material's deflection vs temperature for the pertinent range(s).

This website contains a great deal of information about the properties of materials. The address given above lists the coefficient of thermal expansion for more than 3,000 materials. Good luck.

There are many references where one can find characteristics for a given material; matweb is one of the least desirable choices.

one question: Why do you consider matweb one of the least desireable choices?

true, however MatWeb is an exception (along with other places on the web). If you look at the bottom of the datasheet there is often a list of references given. Admittedly this data often has no test method given nor any info on various preperation procedures. Using that level of skepticism though the only desireable choice is the ASM Metals Handbooks, These are very expensive, and more than complete, however they are sure to contain an error or two.
Even the Guide to Engineered Materials published by ASM in AM&P every december has errors.
I gues I just havent found a fatal flaw yet in matweb and wonder if there really are any.
Not that I would use mat web as a certifiable source. That can only be done by an accreditted lab and or the producer of a material.
