What is H68 brass?
H68 environmental brass is an alloy primarily composed of copper and zinc. It is highly favored due to its excellent processing properties and environmental characteristics. The precise chemical composition ratio of H68 brass enables it to exhibit outstanding performance in multiple industrial fields.
Chemical Composition and Characteristics of H68
In the chemical composition of H68 brass, the copper content accounts for 67% to 70%, with zinc as the balance. This ratio ensures the material's excellent performance in electrical and thermal conductivity, making it highly competitive, especially in electrical and electronic fields. H68 also maintains low impurity levels: lead does not exceed 0.03%, and the contents of impurities such as iron, antimony, bismuth, and phosphorus are all controlled at extremely low levels, with total impurities not exceeding 0.3%. This composition not only enhances the material's mechanical strength but also gives H68 excellent ductility and plasticity, making it suitable for various complex processing techniques.
Application Fields of H68
Electronics and Electrical Industry: Due to its good electrical conductivity, H68 is commonly used to manufacture electrodes and copper busbars, performing excellently in applications requiring high conductivity.
Automotive Manufacturing: H68's corrosion resistance and high strength have led to its widespread application in critical automotive components such as cooling system parts and valves.
Architectural Decoration: Because of its aesthetic and durable properties, H68 is used in manufacturing high-end architectural decorations, such as door handles, railings, and lighting fixtures.
Precision Machining: H68's excellent processing performance makes it suitable for producing precision parts with complex shapes, such as connectors and sensor housings.

Relationship Between Composition Content and Application Fields
The copper content in H68 brass plays a decisive role in its applications in the electronics and electrical industries, ensuring the material's performance in scenarios demanding high conductivity. The proportion of zinc imparts higher strength and corrosion resistance to the material, enabling it to adapt to environments with high mechanical strength requirements and susceptibility to corrosion. The low impurity content further enhances the material's performance in complex processing techniques like cold stamping and deep drawing, leading to its wide application in precision manufacturing fields. It is less prone to cracking or deformation, ensuring the quality and precision of manufactured products.
H68 environmental brass demonstrates unique application value across multiple industries due to its excellent physical properties and compositional advantages, making it an indispensable and important material.

Brass product packaging
We implement a graded and customized packaging system: copper plates are double-wrapped with moisture-proof paper and vapor corrosion inhibitor film before being placed in reinforced wooden crates, which are filled with cushioning materials and equipped with impact-resistant corner protectors; copper tubes and rods are sealed with plastic end caps, wrapped with PE protective film, and then layered into steel-frame logistics containers, with EPE pearl cotton separating each layer; copper wires are automatically wound onto spools, vacuum-sealed, covered with waterproof film, and secured on customized iron-wood pallets; copper strips are wrapped with non-woven fabric, coiled onto high-strength steel cores, and placed into waterproof composite material coils with desiccants inside. All packaging passes ISTA-3A transport testing, and the outer boxes are labeled with international hazardous material identifiers, moisture warnings, and scannable logistics codes, ensuring the cargo withstands moisture, impact, and chemical erosion during global transportation.
