Types and differences of copper

Copper is an important metal material with various types and uses. The following are the main types of copper and their features and uses:

Red Copper
Definition: Red copper refers to pure copper. It is generally called red copper because it has a rose red color and turns purple after an oxide film is formed on the surface.
Features and uses: Red copper has good electrical and thermal conductivity, excellent plasticity, and is easy to process by hot pressing and cold pressing. It is widely used in the manufacture of products that require good electrical conductivity, such as wires, cables, brushes, and special electro-etching copper for electric sparks.

Brass
Definition: Brass is an alloy composed of copper and zinc with a beautiful yellow color.
Features and uses: Brass has good mechanical properties and wear resistance. It can be used to manufacture precision instruments, ship parts, gun shells, faucets, etc.

Bronze
Definition: Bronze is the earliest alloy in the history of metal processing. It is an alloy of tin or lead added to pure steel (red copper). It has special importance and historical significance.
Features and uses: Bronze has good castability, wear resistance and stable chemical properties. It is suitable for casting various utensils, mechanical parts, bearings, gears, etc.

White Copper
Definition: White copper is a copper-based alloy with nickel as the main added element. It is silvery white and has a metallic luster, hence the name white copper.
Features and uses: White copper has higher mechanical and physical properties than other copper alloys. At the same time, white copper has excellent ductility and hardness, and is widely used in electrical appliances, instruments, medical equipment, etc.

Other Classification Methods
In addition to the above classification methods, copper can also be classified according to different aspects such as purity, shape and application.The color of copper can also vary due to the different impurities it contains.
In summary, the types of copper mainly include red copper, brass, bronze and white copper. They each have their own characteristics and uses, and play an important role in different industrial and civil fields.
