Copper, as an ancient metal material, has played an indispensable role in tool making, architectural decoration, artistic creation and other fields since the beginning of human civilization.
With the progress of science and technology and the development of society, people not only mastered how to refine high-purity copper, but also learned to improve and expand the performance of copper through the alloying method, brass is one of the most well-known copper alloy.
Today, we will talk about the difference between brass and pure copper, and their respective applications!
What is pure copper? Pure copper is usually also called purple copper, purple copper is generally more than 99%, more pure electrolytic copper or oxygen-free copper, refers to the copper content of 99.9% or more of the copper material.
Pure copper has good electrical and thermal conductivity, and is widely used as the core material for wires and cables in electrical engineering; meanwhile, due to its excellent ductility and processability, pure copper is also ideal for making various precision parts.
In addition, pure copper has excellent corrosion resistance, especially in freshwater environments, and is therefore commonly used in areas such as piping systems and marine equipment.
In terms of artistic creation, pure copper can be forged into beautiful sculptures or cast into large objects such as bells and tripods, showing great aesthetic value.
What is brass? Brass is a binary alloy composed of copper and zinc. According to the different zinc content, brass can be divided into common brass (such as H62, H68) and special brass (such as lead brass, aluminum brass).
Generally speaking, when the proportion of zinc increases, the color of brass will gradually become lighter, and the hardness will also increase, but the plasticity will be reduced accordingly. Compared with pure copper, brass has better strength and wear resistance, which makes it widely used in the mechanical manufacturing industry, such as brass gears, bearings and other parts can withstand higher pressure without deformation or wear.
In addition, due to the brass surface is easy to form a layer of dense oxide film, which improves the corrosion resistance, especially in the air is not easy to erosion, so it is also used in a large number of decorations, musical instrument shells and so on.
Next, let's talk about the performance comparison and application areas of pure copper and brass!
In terms of physical properties, pure copper has higher electrical and thermal conductivity, while brass shows better mechanical strength and wear resistance.
As far as chemical stability is concerned, although both are more resistant to most acid and alkali solutions, under certain conditions (e.g. seawater, ammonia), stress corrosion cracking may occur in brass, while pure copper is relatively more stable. As for the price factor, usually, because brass contains a certain proportion of cheaper zinc, so the cost will be a little lower than pure copper.
In the field of power transmission, given the excellent conductivity of pure copper, it becomes one of the most commonly used materials in power transmission lines. Whether it's overhead wires on high-voltage transmission towers or small electrical wires inside the home, almost all of them are made of pure copper.
In the field of architectural decoration, brass, with its unique golden luster and ease of processing and forming, has taken its place in the interior and exterior decoration of buildings. Door handles, handrails, lamps and other decorative parts often use brass as raw material, which is both beautiful and durable.
In the field of machinery manufacturing, brass is undoubtedly a good choice for parts that require high strength and good cutting properties. Piston pins in automobile engines, connecting rods, small head bushings and hydraulic systems, such as the valve body and other key parts are mostly made of brass.
In the field of musical instrument manufacturing, brass is the main material for manufacturing many wind instruments in orchestras, such as horns and trombones. These instruments utilize the unique sound conduction properties and appearance texture of brass, giving music a rich emotional expression.
In the field of daily necessities manufacturing, many of the common items in daily life, such as faucets, locks, zippers, etc., are made of brass because they not only have a beautiful appearance, but also have a long service life.
To sum up, pure copper and brass have their own merits, and show their respective superiority in different application scenarios.
With the rapid change of new material technology, we believe that these two materials will continue to find their place in more emerging areas, to promote scientific and technological progress and social development to make greater contributions. Whether in traditional industrial production or modern art design, pure copper and brass will continue to shine with their unique charms and write a new chapter for them.
