Differences in Chemical Composition
Copper Content
H62 Brass: Copper content is 60.5%–63.5%, with zinc as the remainder.
H59 Brass: Copper content is 57.0%–60.0%, with zinc as the remainder.
Impurity Control
H62 Brass: Total impurity content ≤ 0.5%
H59 Brass: Total impurity content ≤ 1.0%
Alloying Elements
Both are ordinary brass, consisting only of a copper-zinc binary alloy.
Special brass alloys include additional elements such as lead or tin (e.g., HPb59-1), but H59 and H62 themselves do not contain other alloying elements.
Comparison of Mechanical Properties
Strength and Hardness
H62 Brass: Tensile strength ≥ 294 MPa; higher hardness, offering superior wear resistance.
H59 Brass: Tensile strength ≥ 294 MPa, but its strength and hardness are slightly lower than H62.
Plasticity (Ductility)
H59 Brass: Higher zinc content provides better ductility and weldability, making it suitable for complex forming processes.
H62 Brass: Exhibits good plasticity, but requires attention to medium-temperature brittleness (200–700°C) during hot working.
Machining Characteristics
H62 Brass: Good machinability, but offers greater cutting resistance during turning, requiring high-quality cutting tools.
H59 Brass: Superior machinability with lower cutting force, making it suitable for precision machining and batch production.

Differentiation of Application Scenarios
H62 Suitable Fields
High-wear parts: Valves, gears, nuts, washers.
Precision instruments: Power contacts, housing clips-scenarios requiring high strength and corrosion resistance.
Water pipe fittings: Utilizing its corrosion resistance and structural strength.
H59 Suitable Fields
Low-cost, high-load components: Pins, rivets, springs.
Decorative parts: Complex-formed items like brass buttons, watch straps, bracelets.
Electrical and electronics: Switches, gaskets, battery contact sheets.
Adaptation to Specific Environments
H62 Brass: More suitable for humid or corrosive environments (e.g., shipbuilding industry).
H59 Brass: Performs well in hot pressure processing, making it suitable for hot-working scenarios.
Comparison of Other Properties
Corrosion Resistance
H62 Brass: Corrosion resistance is superior to H59, particularly more stable in humid environments.
H59 Brass: May offer better resistance in certain corrosive environments due to its higher zinc content.
Cost and Cost-Effectiveness
H59 Brass: The most economical brass, suitable for low-cost applications.
H62 Brass: Offers better performance at a slightly higher cost, suitable for scenarios demanding higher strength and corrosion resistance.
Safety and Reliability
Both are copper-zinc alloys; their safety depends on specific usage and environment.
Both can be considered safe and reliable under normal conditions, provided correct operating procedures are followed.
Our factory
Our factory serves as the core base for the precision manufacturing of copper products, integrating advanced equipment, strict quality control, and efficient production capacity. We possess a complete production line covering the entire process from raw material smelting and continuous rolling to precision drawing/cutting, with key equipment including large-tonnage hydraulic stretching machines, high-precision CNC machine tools, and automated surface treatment systems. 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.
