What is H62 brass?
H62 copper alloy is a common brass alloy with copper and zinc as its main components, averaging about 62% copper, with the balance being zinc and trace impurities. This alloy belongs to the α+β dual-phase brass family, exhibiting both hot and cold-state plasticity, with a tensile strength of 410-630 MPa. It is suitable for manufacturing deep-drawn parts and industrial components such as pins, washers, and radiators. It has good machinability, weldability, and corrosion resistance, but there is a risk of corrosion cracking.

Tensile Strength and Yield Strength
H62 brass, as a commonly used alloy, displays a tensile strength typically in the range of 370 to 420 MPa. This metric indicates the maximum stress that H62 brass can withstand while being stretched or pulled before breaking. The yield strength, generally between 260 to 300 MPa, marks the stress at which a permanent deformation of 0.2% of the original dimension occurs. These properties make H62 brass suitable for applications requiring moderate strength and good formability.
Elongation and Hardness (Vickers and Rockwell)
The elongation of H62 brass, which typically lies between 10% and 15%, reflects its ability to undergo plastic deformation prior to fracturing. This measure is crucial for processes involving bending and forming. In terms of hardness, the alloy is assessed via the Vickers and Rockwell (B scale) hardness tests, with typical values ranging from 100 to 140 VHN and 60 to 80 HRB, respectively. This hardness level contributes to the alloy's resistance to surface wear and deformation under load.
Density and Thermal Conductivity
H62 brass has a density of approximately 8.4 to 8.5 g/cm³, influencing its weight and structural applications where mass is a consideration. Its thermal conductivity, important in applications such as heat exchangers and radiator components, typically spans from 120 to 150 W/m·K. This high thermal conductivity facilitates the efficient transfer of heat, beneficial in cooling systems and other thermal applications.
Corrosion Resistance and Wear Resistance
The corrosion resistance of H62 brass is characterized by its ability to withstand degradation from environmental exposure, including from moisture and atmospheric conditions. This property is particularly enhanced by its zinc content, which contributes to the formation of a protective oxide layer. Wear resistance in H62 brass is considered moderate to good, making it suitable for components that experience regular physical contact and friction, ensuring longevity and reliability in such applications.

Our factory
Our modern production base is equipped with advanced full-process production lines dedicated to the manufacturing of copper and copper alloy products. The factory features precision smelting, continuous casting, high-pressure extrusion, high-speed rolling, and precision cutting equipment, ensuring strict control over every step from copper ingot to finished product. We possess strong R&D and customization capabilities, enabling us to produce various specifications and tempers of copper tubes, plates, rods, wires, and ultra-thin foils in accordance with international standards (such as ASTM, EN, JIS) and specific customer requirements. Our products are widely used in various industries, including refrigeration, electronics, power, transportation, and construction.
Copper product packaging
We fully understand that secure packaging is essential for the flawless delivery of products. Tailored to the characteristics of different products, we employ customized professional packaging solutions: copper tubes and rods are typically secured with anti-rust inner liners and sturdy wooden crates or iron-frame boxes to prevent impact and deformation during transit; copper plates, strips, and foils are first covered with protective film, placed in a dry environment, wrapped with waterproof paper and moisture-proof materials, and finally packed into reinforced plywood crates or steel coil boxes to effectively resist moisture and mechanical damage; wires are neatly wound onto wooden or steel reels and firmly strapped. All packaging is clearly labeled and compliant with export standards, ensuring that your goods maintain their excellent factory condition even after long-distance sea transportation and multiple handlings.
