Question

what are the physical properties of copper, aluminum and brass?

Answer 1

Copper: reddish brown colour, very good conductivity, highly malleable, melting point at 1083ºC
Aluminum: silvery white colour, very malleable, good conductor of heat and electricity
Brass: low melting point (900ºC), malleable, colour from yellow/red to /brown/red (depending on the amount of zinc) high heat conductivity and fair good electric conductivity
