What is H62 brass?
H62 brass strip is a common copper alloy material with many properties. In terms of physical properties, it has a pleasant golden-yellow color, making it aesthetically pleasing and often used in decorative applications. Its moderate density, approximately 8.5 g/cm³, allows it to strike a good balance between performance and weight in applications where weight is critical. Mechanically, H62 brass strip possesses high strength and hardness, exhibits good wear resistance, and can withstand a certain degree of external force without easily deforming or damaging. It is suitable for manufacturing parts that need to withstand significant pressure and friction, such as mechanical parts and hardware accessories.
h62 brass equivalent
| Standard System | Equivalent Designation | Key Notes & Composition |
|---|---|---|
| China (GB/T) | H62 | The original Chinese standard designation. |
| United States (UNS/ASTM) | C28000 | The primary and most critical international identifier. The UNS (Unified Numbering System) code is the global lingua franca for material specifications in trade and engineering. |
| European Union (EN/DIN) | CuZn37 | The most precise and commonly used European equivalent, indicating a nominal composition of ~63% Cu, 37% Zn. CuZn38 is also sometimes referenced due to the allowed composition range. |
| Japan (JIS) | C2800 | Essentially identical in composition to UNS C28000. The difference is typically just in the number of digits (JIS uses C2800, ASTM uses C28000). |
| International (ISO) | CuZn37 | Aligns with the European standard designation. |

FAQ
| Is H62 brass better than 360 brass? H62 Brass: Offers good strength, ductility, and corrosion resistance, making it suitable for forming and bending operations. 360 Brass: Known for its exceptional machinability due to the added lead, but it is slightly less ductile compared to H62. |
| What is the difference between H65 and H62 brass? H62 brass, with slightly lower copper content, is versatile and widely used in plumbing, electrical components, and hardware. In contrast, H65 brass boasts higher tensile strength, better corrosion resistance, and superior machinability, making it ideal for decorative items, musical instruments, and radiator cores. |
| What is the difference between H59 and H62 brass? Their primary differences lie in their composition; H59 contains slightly less copper, making it more malleable but less corrosion-resistant than H62, which contains higher levels of copper for increased durability and environmental resistance. |
| What is H62? H62 is a brass-zinc alloy containing 60.5–63.5% brass. It has good mechanical properties and electrical conductivity. Although cost-effective, it is susceptible to dezincification corrosion, making it suitable mainly for general structural parts. |
| What is the tensile strength of H62 brass? Tensile strength ≥ 330 MPa, elongation ≥ 10% (in the hard state), excellent cold/hot working performance. Suitable for processes such as stamping, drawing, forging, etc. |
| Is H62 brass machinability? More importantly, H62 brass has better machinability than many other brass alloys, which means that manufacturers can produce high-quality parts more efficiently, reducing waste and costs in the production process. |
