Comparison Between Brass and Pure Copper: Characteristics and Properties of Each Type

Brass and pure copper (also known as red copper) are two commonly used metallic materials with a wide range of applications—from industrial to decorative. Although both are derived from copper, they differ in composition, physical properties, uses, and value. This article will help you clearly understand the differences between these two materials and choose the right one for your needs.

Overview of Brass

Brass is a significant alloy made primarily of copper (Cu) and zinc (Zn). It has a distinctive bright yellow color and is widely used across various industries. The ratio between copper and zinc can vary, resulting in different types of brass with varying hardness, ductility, and corrosion resistance. Typically, brass contains between 5–45% zinc, with copper making up the remainder.

One of the standout features of brass is its ease of machining and forming, making it an ideal choice for products like electronic components, decorative fittings, and mechanical parts. Brass also has good electrical and thermal conductivity, making it valuable in electrical and thermal applications, especially in the automotive and electronics industries. Its durability and corrosion resistance contribute to a longer product lifespan, particularly in harsh environments.

Overview of Pure Copper (Red Copper)

Pure copper, often referred to as red copper, is a type of copper with a purity of 99% or higher. It has a characteristic reddish-pink color and is favored for applications requiring excellent electrical and thermal conductivity. Its ductility and workability make it a key material in the production of electrical wires, electronic devices, and other industrial products.

Red copper, being nearly free of impurities, is one of the best conductors of electricity and heat, second only to silver. As a result, it is widely used in electronics and power industries to enhance transmission efficiency. Additionally, red copper is aesthetically pleasing, making it popular for artistic and decorative items. However, it is prone to oxidation when exposed to the environment, forming a brown or green patina, though this can be cleaned and polished to restore its natural shine.

Applications of Red Copper in Daily Life

Thanks to its conductivity, durability, and versatility, red copper is used in various fields:

• Electronics and Power Industry: It is the primary material for making electrical wires, printed circuit boards, and electronic devices due to its excellent conductivity. High-performance and long-lasting materials are essential in this sector.
• Mechanical Engineering: Red copper is used for manufacturing mechanical parts, heat exchange tubes, and plumbing due to its corrosion resistance and malleability.
• Interior Decor and Handicrafts: With its distinct color and easy workability, red copper is popular for making decorative items, sculptures, and high-end furniture. Its classic, luxurious appeal suits artistic interior designs.
• Healthcare: Red copper is also used in producing medical tools, thanks to its natural antibacterial properties. Some studies show that copper can eliminate bacteria on surfaces, helping reduce infection risks.

How Much Does Pure Copper Cost?

The price of pure copper varies depending on the global metals market and usage demand. Given its superior electrical and thermal conductivity, it is usually more expensive than many other metals and subject to market fluctuations. For accurate pricing, you should consult reputable metal exchanges or suppliers. Typically, the price ranges from several hundred thousand to several million VND per kilogram, depending on supply-demand dynamics and global metal prices.

Comparison Between Brass and Pure Copper

To better distinguish between brass and pure copper, here are the main differences:

Criteria	Brass	Pure Copper (Red Copper)
Composition	Alloy of copper and zinc	99% or higher pure copper
Mechanical Properties	Harder and stronger due to zinc	Softer, more ductile, superior conductivity
Corrosion Resistance	Excellent, especially in marine environments	Good, but oxidizes into a greenish patina
Color	Bright yellow, shiny	Reddish-pink, can oxidize to brown/green
Price	Lower	Higher due to purity and conductivity

Should You Use Red Copper or Brass?

The choice between red copper and brass depends on your intended use. If you need a material with high strength, good load-bearing capacity, and resistance to oxidation in marine environments, brass is the better option. Especially for applications that value aesthetics, brass’s golden hue adds a beautiful highlight.

On the other hand, if your usage requires high electrical and thermal conductivity and easy formability, red copper is the more suitable choice—especially in the electronics and electrical industries. Red copper is also ideal for fine arts, sculpture, and decorative interior items, offering a touch of elegance and uniqueness.

Pure Copper Pricing

The price of pure copper varies based on market conditions, timing, and the supplier. For the most accurate and up-to-date price quotes, it’s best to contact reliable suppliers directly. Prices fluctuate according to global metal trends and industrial demand.
