On the other hand, the bronze article indicates that "bronze" is a general term for copper alloys, and therefore includes brass: brass, a subset of the bronze alloys in which zinc is the principal additive I am not qualified to judge which of these is correct, but they seem to contradict each other.

Bell bronze is a two-phase alloy, meaning some of the tin is not dissolved in the copper grains but exists between them. This makes the metal harder and more brittle than a single-phase alloy, and also affects the way the metal responds to hardening by hammering and lathing, and greatly restricts the use of mechanised techniques of manufacture.
A bronze is an alloy of copper and other metals, most often tin, but also aluminium and silicon. Aluminium bronzes are alloys of copper and aluminium. The content of aluminium ranges mostly between 5% and 11%.
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon).
The brass article seems to imply that, while some brasses are called "bronze", this is incorrect: . Some types of brass are called bronzes, despite their high zinc content. On the other hand, this article indicates that "bronze" is a general term for copper alloys, and therefore includes brass:
Brass is more malleable than bronze or zinc. The relatively low melting point of brass (900 to 940 °C; 1,650 to 1,720 °F, depending on composition) and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc, the properties of the brass can be changed, allowing hard and soft brasses.
More than one third, 36%, of unmarried Americans say they're embarrassed to be fully transparent about their finances with the person they’re dating, according to the U.S. Bank survey.
As Hephaestus was an iron-age smith, not a bronze-age smith, the connection would be one from ancient folk memory. [ 26 ] A well-preserved mummy of a man who lived around 3,200 BC [ 27 ] found in the Ötztal Alps , popularly known as Ötzi , showed high levels of both copper particles and arsenic in his hair.
