What is H68 brass?
H68A Brass Rod is an alloy material primarily composed of copper and zinc. Its chemical composition maintains a copper content in the range of 67.0–70.0% and contains trace amounts of arsenic (As 0.03–0.06) to enhance corrosion resistance. This material can be obtained in various forms such as strips, busbars, and plates through customized production, possessing good machining performance and plastic forming capabilities. As an industrial base material, the product is mainly used in the construction of structural components and the manufacturing of mechanical parts. Production enterprises ensure the material's physical and chemical properties meet industrial standards through equipment such as X-ray fluorescence spectrometers.
Material Characteristics
H68A Brass Rod adheres to specific alloy proportion standards. Its chemical composition includes:
Copper (Cu): 67.0–70.0%
Nickel (Ni): ≤ 0.5%
Iron (Fe): ≤ 0.10%
Lead (Pb): ≤ 0.03%
Arsenic (As): 0.03–0.06%
Zinc (Zn): Balance
Impurities: ≤ 0.3%
The addition of trace arsenic significantly improves the material's resistance to dezincification corrosion, making it more suitable for industrial applications in humid environments. Zinc, as the main regulating element in the alloy matrix, is balanced in proportion to achieve a balance between the material's strength and formability.
Industrial Production Standards
Manufacturers implement a strict quality control system, using X-ray fluorescence spectrometers for rapid composition analysis and ICP spectrometers for trace element detection. The total impurities in the product are controlled within 0.3%, ensuring compositional consistency between batches. According to industrial application needs, rod products with different cross-sectional shapes can be provided, including round, square, and special-shaped specifications.
This material is primarily used in the following industrial scenarios:
Construction Industry: Structural supports, connecting fasteners.
Machinery Manufacturing: Bearing cages, gear blanks.
Fluid Systems: Valve components, pump body parts.
Its good cold and hot working performance supports secondary processing techniques such as stamping and turning.
Supporting Testing System
Metallographic Microscopes: Observe microstructural uniformity.
Electronic Universal Testing Machines: Test tensile strength and elongation.
Salt Spray Test Chambers: Evaluate corrosion resistance performance.
All test data is entered into a quality traceability system, supporting full lifecycle product management.

Certified with international standards such as ISO9001 and IATF16949, we are capable of providing global customers with one-stop copper material solutions.
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.
