Bronze is a color, Brass is a specific type of clustering of weather
durable metals, Bronze for instance can be used with fresh water, but
transitions between other metals and crude brass require yellow brass
or else the connection will undergo electrolysis.

Bronze is the traditional name for a broad range of alloys of copper.
It is usually copper with zinc and tin but it is not limited to those
metals.

Source Wikipedia.

"
Brass is an alloy of copper and zinc. Some types of brass are called
bronzes, despite their high zinc content.

Brass is a versatile manufacturing material because of its hardness
and workability. Alpha brasses, with less than 40% zinc, are
malleable and can be worked cold. Beta brasses, with a higher zinc
content, can only be worked hot, but are harder and stronger. White
brass, with more than 45% zinc, is too brittle for general use. Some
types of brass have other metals added to modify their properties.
Brass has a yellow colour, somewhat similar to gold. Because of this,
and its relative resistance to tarnishing it is used as a decoration.

IOW Brass is a type of Bronze with alot of Zinc.

Also you should read what Wikipedia says about Bronze.

"
Bronze was also stronger than iron, another common metal of the era,
and quality steels were not available until thousands of years later.
Nevertheless the Bronze Age gave way to the Iron Age as the shipping
of tin around the Mediterranean ended during the major population
migrations around 1200 ? 1100 BC, which dramatically limited supplies
and raised prices. Bronze was still used to a considerable extent
during the Iron Age, but for many purposes the weaker iron was
sufficiently strong to serve in its place. As an example, Roman
officers were equipped with bronze swords while foot soldiers had to
make do with iron blades.
