The Differences Among Brass, Red Copper, Bronze And Cupronickel

1. The colors are different.
The color of brass is yellow, the color of copper is purple-red, the color of bronze is blue, and the color of white copper is silver-white.

2. The chemical elements of the composition are different.

Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is composed of two or more elements, the elements that are often added are lead, tin, aluminum, etc. Various alloys are called special brass.

Red copper is a relatively pure copper, which can generally be regarded as pure copper, but it is not necessarily pure copper, and sometimes a small amount of deoxidizing elements or other elements are added to improve the material and performance, so it is also classified as a copper alloy.

Bronze is an alloy of pure copper (red copper) added with tin or lead.

Cupronickel is a copper-based alloy with nickel as the main additive element. The copper-nickel binary alloy is called ordinary cupronickel; the cupronickel alloy with manganese, iron, zinc, aluminum, and other elements is called complex cupronickel.

3. Different uses.

Brass has strong wear resistance, and it is often used to manufacture valves, water pipes, connecting pipes for internal and external air conditioners, and radiators.

The electrical conductivity and thermal conductivity of red copper are second only to silver, and are widely used in the production of electrical and thermal conductivity equipment. Copper has good corrosion resistance in the atmosphere, seawater and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkalis, salt solutions, and various organic acids (acetic acid, citric acid).

Bronze has the characteristics of low melting point, high hardness, strong plasticity, wear resistance, corrosion resistance, bright color, etc. It is suitable for casting various appliances, mechanical parts, bearings, gears, etc.
 

Compared with other copper alloys, cupronickel has exceptionally good mechanical and physical properties, good ductility, high hardness, beautiful color, corrosion resistance, and deep-drawing properties. It is widely used in shipbuilding, petrochemical, electrical appliances, instruments, medical equipment, daily necessities , handicrafts, and other fields, and is also an important resistance and thermocouple alloys.
