Question

Why are the physical properties of brass different from the physical properties of pure copper?

Answer 1

I guess, it's because brass in not pure copper but an alloy of copper therefore it has other atoms within it's cristalin structure witch in terms means other bonds between atoms so other properties  

Answer 2

Brass is a combination of zinc and copper, so it is an alloy, which by itself is a reason for the difference in properties.

If you are getting more detailed about it, you might want to look into the molecular arrangement, because when you combine different metals into alloys, the properties are directly dependant on the arrangement of the different metal atoms in the substance. For example, there are different types of brass, each with its own properties, that is determined by the ratio of copper to zinc in the mixture.

Answer 3

Because brass is an alloy made up of tin and copper.
