What is H62 brass?
H62 brass, with a slightly higher copper content, offers a better balance of mechanical performance, corrosion resistance, and aesthetic consistency, making it a premium choice for specific applications.
What are the material properties of H62 brass?
| Property Type | Characteristics |
|---|---|
| Mechanical | - Strength: Tensile strength ~330–400 MPa (annealed), can be increased by cold working. - Ductility: Moderate at room temperature; better hot workability (excellent for hot forging/extrusion). - Machinability: Fair to good (better than α-brasses due to β-phase chip-breaking). |
| Physical | - Density: ~8.43 g/cm³. - Conductivity: Moderate electrical & thermal conductivity (lower than pure copper). - Color: Golden yellow, aesthetically appealing. |
| Corrosion | Generally good atmospheric and water corrosion resistance. Susceptible to dezincification in certain water/chemical environments and to ammonia-induced stress corrosion cracking. |
| Fabrication | Excellent for hot working (forging, rolling, extrusion). Suitable for cold working with intermediate annealing. Easily soldered, brazed, and welded. |
Applications
H62 brass is an alloy with myriad applications ranging from plumbing fittings to automotive parts because of their strength, ductility, and appearance. Its unique characteristics make it best suited for a range of applications including plumbing fittings because of water corrosion resistance, electrical components because of water conductivity, and decorative hardware due to the golden hue.

In-Depth Discussion on H62 Brass Chemical Composition
H62 brass is mainly a copper (Cu) and zinc (Zn) alloy along with some trace quantities of other elements depending on one property that should be enhanced. Standard H62 brass has a copper content that ranges from 60.5% to 63.5%, with the zinc content ranging from 36.5% to 39.5%. These values could fluctuate slightly depending on custom specifications or manufacturing standards. A copper-rich alloy gives H62 brass good corrosion resistance and high malleability, whereas the zinc content gives it strength and hardness.
Very small quantities of impurities or additional elements are also present, such as lead (Pb), iron (Fe), or sulfur (S), each below 0.5%, depending upon the process of production or environment in which the material is going to be used. For example, lead will be added to improve machining operations, whereas a low level of iron may enhance wear resistance.
This compromise in the composition makes H62 brass a highly versatile alloy, suitable for many applications, industrial or decorative. Its chemical nature ensures the strength and workability required by any reactive environment, and this is why it persists in modern production as the most commonly used brass.
Copper and Zinc in H62 Brass
The basic compositions of H62 brass are copper and zinc, which together create the particular qualities of the alloy. In general, about 60 to 63% of the alloy consists of copper, whereas the rest is made up of 37 to 40% zinc. This range is based on a fine balance chosen by the manufacturers between strength, malleability, and corrosion resistance, leaving H62 brass open to numerous applications.
The highest content of copper largely adds to the metals' thermal and electrical conductivity character and corrosion resistance in various environments, including moisture and some acids. It controls the ductility of the material, which allows shaping or machining into intricate components without cracking.
On the contrary, zinc offers strength and wear resistance. It makes the alloy hard enough to withstand mechanical strain, hence the manufacture of gears, bearings, and valves. Zinc serves to lessen the price of the alloy without seriously compromising its performance, thus contributing to its economic worth for industrial use.
The particular blend of copper and zinc in H62 brass yields a balance of mechanical and chemical properties, as well as machining and long lifetimes. By virtue of this perfect combination, H62 brass finds application in manufacturing automotive parts, electrical connectors, and decorative-related materials.

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.
