What is H62 brass?
H62 brass belongs to the national standard, the implementation standard: GB/T 5232-2001 brass chemical composition table. Copper content 62%, also known as daily brass. Suitable for electrical appliances, electronics, lighting, hardware, mounting horizontal, switch, gasket, gasket, battery contact, copper buttons, watch bands, decorative necklaces, bracelets, rings and other copper products.
H62 copper alloy equivalent grade
| Standard | Grade |
|---|---|
| China (GB) | H62 |
| Japan (JIS) | C2801 |
| Germany (DIN) | CuZn37 |
| USA (ASTM) | C27400 |
| Europe (EN) | CW508L |
Despite minor compositional differences, these equivalents share similar properties and applications.

Chemical composition
| Spec Item | H62 (Approx.) |
| Cu (wt.%) | 60.5–63.5 |
| Zn (wt.%) | 36–39.5 |
| Pb (wt.%) | trace / per order |
| Phase | alpha-dominant |
Mechanical and Physical Properties
The dominant alpha phase makes H62 more ductile and balanced:
Performance: Generally more balanced in strength and hardness than H59.
Ductility: Significantly better ductility and elongation.
Forming: Suitable for cold forming processes like bending and riveting.
Corrosion Resistance and Durability
H62's higher copper and single-phase structure improve its long-term stability:
Long-Term Stability: More reliable for components intended for outdoor or long-life exposure.
Finishing: Easier to achieve consistent, high-quality surface finishes for electroplating.
H59 vs H62: Side-by-Side Comparison
Composition and Microstructure (alpha vs beta)
The key difference lies in the microstructure:
H59: The higher proportion of the brittle beta phase (alpha + beta) results in a harder material that naturally forms short, brittle chips during machining.
H62: The predominantly soft and ductile alpha phase ensures better elongation and formability but tends to produce tougher, longer, and stringier chips.
Mechanical Properties
| Property | H59 Brass | H62 Brass | Impact on Final Part and Processing |
| Strength/Hardness | Slightly Higher | Balanced / Slightly Lower | H59: Better for structural rigidity; H62: Better for cold forming. |
| Ductility (Elongation) | Lower (Brittle) | Significantly Higher | H59: Minimal cold working allowed; H62: Suitable for riveting, flaring, or light bending. |
The choice between H59 and H62 brass is a balance of priorities:
H59: Opt for lower cost and highest production speed.
H62: Opt for better corrosion resistance, superior surface finish, and long-term reliability.
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.
