In brass the Zn and Cu are dissolved in one another to form a metallic solution. They do not form a compound in the normal sense that we use the term "compound" meaning a definite molecular composition. In the same sense we do not classify salt dissolved in water as a "compound" because over most of the concentration range the relative amounts of salt and water can be varied continuously. There are some compounds that do form specific compounds with water, and there are some metallic combinations that do have a fixed composition forming inter-metallic compounds.
