Yellow brass comes from brass, a compound that arises from the union of copper and zinc. Copper, in this case, is the most important component of the alloy, and what will give the colour to the compound is the amount of zinc in it (the more zinc there is, the yellower it will be). Since we are talking about yellow brass, the amount of zinc in it will vary between 25-35% (the percentages normally used are between 15% and 75%). It is a material that offers good hardness, is easy to mould, has good thermal conductivity, is corrosion resistant and has a high resistance to oxidation and corrosion, even with high percentages of salinity. It is also characterised by its cold or hot workability.
