H59 copper and H62 copper are both types of brass in alloy materials, but due to differences in their chemical composition and properties, different copper alloys are used in different industries.
Chemical Composition
H59 copper has a copper content between 57.0% and 60.0%, while H62 copper has a copper content between 60.5% and 63.5%. H59 copper has a higher zinc content, generally above 48%, while H62 copper has a relatively lower zinc content, around 39%. This difference in composition leads to differences in their mechanical and processing properties.
Mechanical Properties
Due to its higher zinc content, H59 copper has relatively higher strength and hardness, but lower plasticity and toughness. This type of brass is suitable for making parts that need to withstand large loads and impacts, such as bolts and rivets. H62 copper has good plasticity and toughness, capable of withstanding a certain degree of bending and torsion, making it suitable for manufacturing parts requiring bending and shaping, such as water pipe fittings and radiators.
Processing Properties
H59 copper has good casting, machining, and welding properties, and is easy to hot-press and cold-press. H62 copper also has good casting, machining, and welding properties, but its hot-pressing performance is poorer than H59 copper, making it more prone to hot brittleness.
Application Areas
Due to the differences in properties, H59 and H62 copper have different applications. H59 copper is suitable for manufacturing parts requiring high strength and wear resistance, such as bearings, gears, and worm gears. H62 copper is suitable for manufacturing parts requiring good plasticity and bending performance, such as water pipe fittings, radiators, and waveguides.

Copper Packaging
Our copper products all employ professional graded packaging to ensure transportation safety and product integrity: Copper tubes and rods are tightly wrapped with moisture-proof stretch film and secured on reinforced wooden pallets, with extra corner protectors for extra-long tubes; Copper plates, strips, and wire coils are lined with waterproof paper or plastic film, fixed externally with sturdy wooden crates or steel-strapped solid wooden pallets, and include VCI (Volatile Corrosion Inhibitor) paper inside to prevent corrosion. All packages are clearly marked with product information, lifting symbols, and moisture/impact warnings, and can be customized according to client requirements to ensure safe delivery to destinations worldwide.
