i have been given a chemistry homework, and i have to create a product made of aluminium and explain why it costs that price, (electromagnetism?) i chose a bike so now i have to say how much the aluminium costs and why, and all the other parts etc. etc.
Also Aluminum to Aluminum or to steel contact in moving parts tend to seize, so there will need to be bushings for any moving areas such as hubs and brakes.
