What are the classification, sources, colours, properties and commercial uses of acrylic, aluminium and stainless steel? *Scientifically correct answers if possible. By commerical uses I mean the general term (e.g. kitchen utensils) not- aluminium foil, stainless steel pan, the product itself. Also try to include your sources/urls/links/book titles/etc. Thanks in advance.P.s. this is for design and technology homework

That's a pretty broad question. I think the best way to answer it is to give some general resources. See below for commonly used web sources for technical data on materials. I'm less well versed in plastics than metals, so I can tell you less about acrylic than aluminum and stainless steel. Aluminum is generally used where low weight is needed, although it's strength to weight ratio is similar to steel. Aluminum tends to have worse fatigue strength and tends to crack in cyclic loading, but sometimes where a cross-section is needed it can provide weight savings. Aluminum comes in sheets, tubes, rods, and can be cast. Stainless steel is more expensive and is used where corrosion resistance is important, in applications such as liquid containers, sanitation critical components such as kitchen utinsels, food preparation surfaces and sinks, and in medical equipment where blood and contaminants need to be cleaned and sterilized. It is also used in fasteners where corrosion resistance and strength are needed. Stainless steel is formed from sheets most often and available in tubes and rods, it is not practical for casting as far as I know.
