Properties of material?

what are the physical properties,chemical properties, mechanical properties and availability of the following material.


a. mild steel


b. cast iron


c. Aluminum

Properties of material?
roughly %26amp; briefly :


mild steel is vulnerable towards acids , but it carries good tension %26amp; compression.





cast iron is brittle , so it's failure mode is bad(sudden) , it bears mechanical stresses %26amp; vibrations , so it's good as a frame for machines , but not used in construction unless a decoration , it's also more chemically stable than mild.





alum. it's lighter ,nowaday tech, but less stresses can be born by it than steel , it's major advantage is that it experience no rust , %26amp; it's stable than iron or steel as i know , though it's more chemically active , but that's due to it's protection layer (rust) which is formed around it due to oxidation (it's an activel electrochemical element)
