The discovery of bronze enabled people to create metal objects that were harder and more durable than had previously been possible. Bronze tools, weapons, armor, and building materials such as decorative tiles were harder and more durable than their stone and copper ("Chalcolithic") predecessors.
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%.
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.
Cannon made of bell metal at Malik-e-Maidan, Bijapur, India. Bell metal or bell bronze is an alloy used for making bells and related instruments, such as cymbals.It is a form of bronze with a higher tin content than most other bronzes, usually in approximately a 4:1 ratio of copper to tin (typically, 78% copper, 22% tin by mass).
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.
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.
