because copper is an element and bronze is not. but, also because copper is one of the two elements that make up bronze, which is an alloy. the other element being iron.
Copper is an element by itself
Bronze is a compound - a mixture of copper and tin mainly
There is also brass - copper and zinc mixture
Copper is an element. Bronze is an alloy of copper and tin.
the mixture of copper and tin is made to bronze.
Bronze is an alloy of copper (88 %) and tin (12 %). The concentrations may be variable for different types of bronze; also bronzes can contain and other elements. Bronze was probable the first alloy known by the humankind.
A solution of copper and tin is a mixture at the atomic leverl. No amount of optical magnification can reveal the different metals in the alloy. The mixture is a random arrangement of copper and tin atoms.
There are many different bronze alloys but modern bronze is typically 88% copper and 12% tin. however celestial bronze is 90% copper and 10% tin.
Copper is an element. Bronze is an alloy of copper and tin.
usually it is 67% copper and 33% zinc it can range from 55% to 95%
Bronze is a mixture of copper and tin. Approximately 94% copper is used, and 6% tin. This is only the norm though, as slight differences in percentages up and down are used by different manufacturers.
Because they are both metals. Copper is one of the elements that makes bronze. The other element is iron. So bronze is an alloy. An alloy is a mixture of two or more metals. Therefore, they are iron and copper. So copper and bronze are mostly different, except the fact they are both metals.
Copper was a significant resource in the Bronze Age as. along with tin, copper is a component of bronze.
steel,copper,and bronze
the mixture of copper and tin is made to bronze.
Bronze is the mixture of tin and copper. Bronze is an alloy that is much harder than copper. Many things were made out of bronze in a time period known as the Bronze Age.
Bronze is an alloy of 90% copper, and 10% tin.Brass may have a wide range of different contributory metals which confer different properties on the alloy.
Bronze antiques are typically made out of bronze metals. Bronze is made out of copper and tin to make it sturdy and tough. Some are often mixed with copper and zinc materials for a different color and composition.
There is no specific ratio for bronze because there are many different bronzes. For example, Aluminium bronze contains 92% copper, 8% aluminium. Phosphor bronze contains 89.75% copper, 10% in and 0.25% phosphorus. Manganese bronze contains 58.5% copper, 39.2% zinc, 1% Iron, 1% tin, 0.3% manganese.
Bronze is an alloy of copper (88 %) and tin (12 %). The concentrations may be variable for different types of bronze; also bronzes can contain and other elements. Bronze was probable the first alloy known by the humankind.
