bronze
Alloys of copper and tin are called "bronze".
The element that can be strengthened by alloying it with zinc or tin is copper. Copper-zinc alloys, known as brass, and copper-tin alloys, known as bronze, are commonly used to improve the strength and corrosion resistance of copper.
Two of the earliest alloys were bronze (copper with tin) and brass (copper with zinc).
Pre Iron Age metalworkers used non-ferrous alloys such as bronze (copper and tin), brass (copper and zinc), and pewter (tin and lead). These alloys were valued for their strength, malleability, and resistance to corrosion, making them ideal for tools, weapons, and decorative items.
There are many different alloys containing mainly copper, some tin and small amounts of other elements. There is, therefore, no precise answer. Generally, though, the ratio of copper to tin will be 997:3
NONE copper is an element and contains only copper - alloys (mixtures of copper combined with other metals) such as brass (copper and zinc) and bronze (copper and tin) both look different and cause the alloys of copper to have different characteristics
The main alloys of copper are Brass (with zinc) and Bronze (with tin).
bronze
Bronze is an alloy made of copper and tin. The Romans, like other peoples in antiquity made alloys with varying percentages of tin and alloys which stood in between bronze and brass (which is an alloy with copper and zinc) by mixing copper, zinc and tin. The earliest tin alloys were made in the 4th millennium BC in Persia, Mesopotamia (present day Iraq) and China. Prior to this bronze was made by mixing copper with arsenic to make arsenic bronze. The use of tin made the bronze which made a superior quality of bronze and whose production was less hazardous. Later in history bronze alloys with tin and stannite (a type of iron) tin and phosphorus, tin and aluminium, aluminium, beryllium and iron have also been produced.

Ltd- Manufacturer and exporter of copper alloys, phosphor bronze alloys, tin bronze alloys, leaded bronze alloys, gun metal alloys, nickel alloys, copper alloy bars, drawn copper bars, copper alloy sheets, copper alloy rods, nickel alloy rods, nickel alloy bars, phosphor bronze alloys rods, phosphor bronze bars, phosphor bronze squares and many more.
Many alloys contain two elements, for example Brass is copper + zinc, Bronze is copper + tin.
Bronze is usually made up of copper (about 90%) and tin (about 10%) Brass is usually made up of copper and zinc. Some alloys are called bronze when they are actually brass, such as "commercial bronze" which is made from copper and zinc. Other metals may also be added, but if the main addition is tin, it's a bronze, and if the main addition is zinc, it's a brass.
