Copper
Brass is a BASE METAL :)
Brass is an alloy (combination) of copper and zinc so is a manufactured metal NOT a base metal that can be mined from the ground.
Brass is an alloy of copper and zinc, with copper being the main component. Both brass and copper are metals, but copper is the base metal from which brass is derived. Copper is a pure elemental metal with a distinct reddish color, whereas brass is a mixture with varying proportions of copper and zinc that can range in color from yellow to red.
Base metal refers to the metal used in the construction of the watch case that is not considered a precious metal like gold or platinum. Common base metals include stainless steel, brass, or aluminum. Watches made with base metal cases are typically more affordable than those made with precious metals.
The base metal of silver plated flatware is typically copper or brass. These metals are less expensive than silver and provide a sturdy foundation for the silver plating.

Tubas are made of metal, frequently brass, hence the name "brasswind" (trumpets, trombones, tubas, etc). This is as opposed to "woodwind" (like flutes and clarinets)
Sulfamic acid may be too aggressive for cleaning brass as it can potentially cause corrosion to the metal. It's recommended to use mild brass cleaners specifically designed for the task to avoid damaging the brass surface.
i need to answer this --> Properties of alloy that are different to and more useful than the main metal... i think this means what do they do?
