Our plate exhibit a range of beneficial properties

Strength and Durability

They are strong and resist wear and tear, making them suitable for high-traffic areas and applications requiring longevity.

Corrosion Resistance

Resist corrosion from water and air, which is crucial in marine and outdoor applications.

Malleability

They can be easily shaped and molded without breaking, allowing for intricate designs and shapes.

Aesthetic Appeal

A natural, golden appearance that adds elegance and sophistication to any setting.

Thermal Conductivity

These plates are good conductors of heat, making them useful in applications where heat distribution is necessary.

Electrical Conductivity

Brass is also an effective conductor of electricity, useful in electrical components.

Physical properties

01/

Appearance

It usually presents a golden yellow metallic color, with a smooth surface and bright luster. Different surface effects can be obtained through various surface treatment processes, such as polishing, brushing, or even antique finishing.

02/

Density

The density of brass is generally between 8.4-8.7g/cm³. For example, the density of commonly used C26000 brass (65% copper, 35% zinc) is about 8.53g/cm³, which is higher than stainless steel and carbon steel.

03/

Melting point

The melting point is relatively lower compared to stainless steel, typically ranging from 880-950℃ depending on the specific brass alloy composition. This makes it easier to cast and process at high temperatures.

04/

Coefficient of thermal expansion

The coefficient of thermal expansion is moderate. In the range of room temperature to 100℃, the coefficient of thermal expansion of brass is approximately 20×10⁻⁶/℃. This property ensures good dimensional stability in environments with temperature fluctuations.

05/

Thermal conductivity

Brass has excellent thermal conductivity, with a thermal conductivity coefficient of about 109-125W/(m・K). This is significantly higher than stainless steel, making brass suitable for heat exchangers and applications requiring efficient heat transfer.

06/

Electrical conductivity

Brass exhibits good electrical conductivity, although it is lower than pure copper. The electrical conductivity of brass is approximately 25-30% that of pure copper, making it suitable for electrical components and connectors.

Chemical properties

Corrosion resistance

Brass has good corrosion resistance, particularly in atmospheric and freshwater environments. A protective oxide layer forms on its surface, preventing further oxidation. However, in the presence of ammonia, certain acids, or highly corrosive media, brass may suffer from stress corrosion cracking or dezincification. Alloys like C27200 (cartridge brass) are specifically designed for enhanced corrosion resistance.

Antioxidation

Brass has moderate oxidation resistance at room temperature but may tarnish over time due to exposure to air and moisture. At elevated temperatures, brass may experience accelerated oxidation, limiting its use in high-temperature environments.

Chemical stability

In general chemical environments, brass exhibits good chemical stability and resists reactions with weak acids and alkalis. However, it is not resistant to strong acids (e.g., nitric acid) or ammonia-containing solutions, where it may corrode or degrade.

Passivation

Unlike stainless steel, brass does not form a passive film naturally. However, it can develop a protective patina over time, which enhances its durability and aesthetic appeal. Surface treatments such as lacquering or electroplating can further improve its corrosion resistance and appearance.
