This process allows the production of wide sheets with improved surface finishes. Brasses whose chemical composition makes them suitable for being formed into the final product by mechanical methods, such as rolling or forging, are called wrought brasses, and the first digit of their designation is I through 7.
The properties of the final alloy can be fine-tuned by altering the amounts of the various elements. Zinc is used to coat objects made from iron and steel to stop them from getting spoiled in a process called rusting. Over three quarters of the chemical elements that occur naturally on our planet are metals, so it's almost easier to say what metal isn't.
The "salt" you might sprinkle on your dinner is a typical example it's the compound that forms when sodium metal reacts with chlorine gas , but it's only one of hundreds of different salts.
When recycled scrap is used, the percentages of copper and other materials in the scrap must be known so that the manufacturer can adjust the amounts of materials to be added in order to achieve the desired brass composition.
How do metals work? Metals have many properties, such as strength, toughness, and stiffness. The only can that is not recyclable at home is a partially full aerosol can which is classified as hazardous waste.

Cold rolling is used where extremely precise dimensions or an attractive finish are required. Carlisle "Carl" Smith.
For example, brass screws are cut from lengths of rod. I think my in-laws did that with some of the pipes under my kitchen sink.
Brasses with a higher percentages of zinc are stronger and harder, but they are also more difficult to form and have less corrosion resistance. Kroschwitz, Jacqueline I. Iron is the most useful metal of all.
