What is the composition of H62 Brass?
H62 brass is what's called an alpha-beta brass. The brass is made up of 62% copper and 38% zinc. The "H" means brass in Chinese nomenclature, and you can see that the number 62 represents the amount of copper in the metal. This blend is pure magic because it provides a good balance between strength and ductility. This is what makes H62 perfect for a wide variety of industrial applications.
There may be small amounts of lead or iron or other elements in here as well to enhance certain properties or improve machinability.
What are the Chemical and Mechanical Properties of H62 Brass?
The best feature of H62 is its mechanical properties. It offers high tensile strength and good plasticity in both hot and cold conditions. The alloy's corrosion resistance makes it suitable for outdoor and industrial environments. Additionally, H62 brass is easy to machine, weld, and solder, which simplifies manufacturing processes.
Applications of H62 Brass
H62 is used to make all kinds of stuff. People use it to make brass tile trims, profiles, plumbing fittings, electrical connectors, and decorative hardware of all types. In the construction industry, people like to use H62 because it's strong and doesn't corrode outside. That makes it useful for architectural fittings and trims. In the electrical industry, they use it for terminals and connectors because of its good conductivity.

Despite minor compositional differences, these equivalents share similar properties and applications.
Key Differences Between H59 and H62 Brass
1. Copper Content
H59 has 59% copper, while H62 has 62%. The higher copper content in H62 gives it slightly greater strength and a more attractive yellowish hue. However, the distinction between the two alloys is relatively minor when weighed against other factors.
2. Zinc Content
H59 contains around 40% zinc, while H62 has slightly less zinc at 36%. This difference influences the hardness of the alloys, with H59 being slightly harder and more durable.
3. Lead Content
One of the most significant differences between H59 and H62 brass is the presence of lead in H62. H59 is free from lead, offering better corrosion resistance and making it more suitable for applications exposed to moisture and saltwater. In contrast, the 2% lead content in H62 enhances machinability but reduces the alloy's ability to resist corrosion.
4. Corrosion Resistance
H59 brass has superior corrosion resistance, particularly in marine or moisture-laden environments, making it ideal for high-demand outdoor applications.
H62 brass, containing lead, has lower corrosion resistance and is more appropriate for indoor applications or environments with limited moisture exposure.
5. Machinability
H62 brass is the clear winner when it comes to machinability. The addition of lead allows for faster cutting speeds, cleaner cuts, and the ability to produce intricate components more easily.
H59 brass, while still machinable, is not as easy to work with due to its lack of lead. This means that it is better suited for projects requiring higher strength, but it may require more effort during manufacturing.
6. Strength and Durability
H59 brass is stronger than H62 and can handle higher stresses and strains without deforming. This makes it the preferred choice for parts that need to withstand extreme pressures, such as mechanical components in engines or marine environments.
H62 brass, although softer, is ideal for smaller components that do not need to endure heavy mechanical stress.
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.
