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.
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.
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.

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.
The baby girl joins their other two children — daughter Sterling Skye, 3, and son Patrick “Bronze” Lavon Mahomes III, 2 — all of whom are either named or nicknamed after types of metal.
Copper would have been especially useful to ancient humans as it was much stronger than gold, hard enough to be made into useful items such as fishhooks and woodworking tools, but still soft enough to be easily shaped, unlike meteoric iron. The same deposits of native copper on the Keweenaw Peninsula and Isle Royale were later mined commercially.
