What is H62 brass?
H62 brass, as a classic copper-zinc alloy material, plays a vital role in industrial production and daily life due to its excellent mechanical properties, workability, and corrosion resistance. This alloy, containing 60.5%–63.5% copper with the remainder primarily zinc, demonstrates unique comprehensive performance through reasonable composition ratio and process control. Its continuously expanding application fields have made it an indispensable basic material in modern manufacturing.
Core Applications in Machinery Manufacturing
In the machinery manufacturing industry, H62 brass is widely used to produce various precision parts due to its good machinability and moderate strength. H62 brass rods can achieve a tensile strength of over 400 MPa after cold working, with elongation maintained at around 15%. This balance between strength and plasticity allows them to withstand complex mechanical stresses, making them suitable for components like gears, bushings, valve parts, and fasteners that require both durability and formability.
Traditional and Innovative Applications in the Electronics and Electrical Industry
As an alloy material with conductivity second only to pure copper, H62 brass holds an important position in the electrical field. Its stable conductivity and oxidation resistance are fully utilized in applications ranging from traditional connectors and terminal blocks to shielding covers in modern micro-circuits. In high-voltage electrical equipment, contact supports made of H62 effectively resist arc erosion, ensuring long-term stable operation. In recent years, with the accelerated construction of 5G base stations, H62 brass has been extensively used in the manufacture of base station antenna oscillators and RF connectors due to its combined electromagnetic shielding performance and cost advantage.

Fusion of Art and Function in Architectural Decoration
The application of H62 brass in the construction industry perfectly demonstrates the integration of its aesthetic value and practical function. H62 sheets, after polishing or brushing, can be used to create door handles and stair railings with a vintage texture, as well as processed into modern-style curtain wall decorative strips. Its natural antibacterial properties and resistance to oxidation make it an ideal choice for high-touch public facility surfaces like hospital handrails and doorknobs, meeting both hygiene and durability requirements.
The Acoustic Secrets in Musical Instrument Manufacturing
Musical instrument manufacturing represents one of the most culturally significant application fields for H62 brass. The bodies of Western brass instruments such as trumpets and trombones are often made from H62 material because its vibration characteristics produce a warm and bright timbre. Traditional Chinese percussion instruments like gongs and cymbals also rely on the specific acoustic response of brass. Instrument craftsmen control the material's modulus of elasticity by adjusting the degree of cold working, thereby precisely tuning pitch and harmonic structure.
Critical Protection in Shipbuilding and Marine Engineering
In harsh marine environments, H62 brass demonstrates excellent corrosion resistance against seawater. It is commonly used for ship propeller shaft sleeves, seawater pipeline valves, and nautical instrument parts. Its corrosion resistance mechanism lies in the dense oxide film formed on the surface, which prevents chloride ion penetration, while the sacrificial anode effect of zinc provides additional protection. In recent years, with the development of deep-sea equipment, specially heat-treated H62 alloy has even been used in manufacturing joint bearings for underwater robots.
Mass-Market Applications in Daily Hardware Products
In daily life, H62 brass serves the public in more accessible forms. From keychains and eyeglass nose pads to high-end fountain pen nibs, its easy workability allows for the realization of complex and intricate designs. Particularly in the high-end lock industry, H62 lock cylinders can withstand over 100,000 wear cycles, far exceeding the durability of aluminum alloy products. Its good plating adhesion also makes it a preferred base material for various plated hardware, ensuring both aesthetic appeal and longevity.

This enables the large-scale and customized production of a wide range of products such as copper rods, tubes, plates, strips, and wires. The factory strictly adheres to the ISO quality management system and is equipped with testing instruments such as spectrometers and mechanical property testing machines to monitor process parameters and product performance throughout the entire process. Digital production management is achieved through an ERP system and visual dashboards, ensuring timely order delivery. Furthermore, we implement a green manufacturing philosophy, equipped with exhaust gas treatment and scrap recycling systems, committed to providing customers with high-quality and sustainable copper material solutions.
Copper product packaging
We employ professional and reliable packaging solutions to comprehensively protect the integrity of all types of copper products during long-distance transportation and handling. For copper rods and tubes, we use moisture- and rust-proof materials for wrapping, secured with sturdy wooden crates or steel strapping to prevent bending and deformation. Copper plates and strips are sealed with waterproof paper or plastic film, protected with edge guards, and then fixed on customized wooden pallets or metal racks to avoid surface scratches and moisture. Copper wires are neatly wound on specialized reels, wrapped with moisture- and rust-proof film, and reinforced at the edges. All packaging is designed according to export standards, with clear labeling to ensure the safe delivery of goods to our global customers.
