H62 brass is a widely used copper alloy material in industrial production due to its excellent mechanical and physical properties. This article details the physical properties of H62 brass and provides specific numerical data to help readers gain a deeper understanding of the characteristics of this material.
Basic Composition of H62 Brass
The primary components of H62 brass are copper (Cu) and zinc (Zn), with copper content approximately 60.5%-63.5% and zinc making up the remainder. Additionally, H62 brass contains trace amounts of elements such as lead (Pb), iron (Fe), beryllium (Be), antimony (Sb), tin (Sn), and sulfur (S). The presence of these elements influences the properties of H62 brass to a certain extent.
Density
The density of H62 brass is about 8.4 g/cm³. This density gives it a combination of weight and strength advantages, making it suitable for manufacturing components that require both weight and mechanical strength.
Melting Point
The melting point range of H62 brass is 900°C to 940°C. Due to its relatively high melting point, H62 brass maintains good physical properties and chemical stability in high-temperature environments, making it widely used in components such as heat exchangers and radiators that need to operate in high-temperature conditions.
Thermal Conductivity
The thermal conductivity of H62 brass is approximately 120 W/(m·K). Its high thermal conductivity makes H62 brass excellent for heat exchange and heat dissipation applications, particularly in devices like radiators and heat exchangers that require efficient heat transfer. H62 brass is an ideal material choice for such applications.
Electrical Conductivity
The electrical conductivity of H62 brass is about 28% IACS (International Annealed Copper Standard). While not as high as that of pure copper, this conductivity is sufficient for most applications, especially in scenarios that require a balance between strength and conductivity.

Coefficient of Linear Expansion
The coefficient of linear expansion for H62 brass is approximately 20.7 × 10⁻⁶/°C. This means that during temperature changes, the dimensional changes of H62 brass are relatively small, offering good dimensional stability. This property makes it suitable for manufacturing precision instruments and equipment.
Specific Heat Capacity
The specific heat capacity of H62 brass is about 0.377 J/(g·°C). Its relatively high specific heat capacity allows it to absorb more heat in environments with significant temperature fluctuations, thereby mitigating the impact of temperature changes on material performance.
Mechanical Properties
Tensile Strength: The tensile strength of H62 brass ranges from approximately 340 MPa to 540 MPa. This indicates that H62 brass possesses relatively high tensile strength and can withstand significant tensile stress without breaking easily.
Yield Strength: The yield strength of H62 brass ranges from about 110 MPa to 360 MPa. Exceeding this stress causes the material to undergo plastic deformation without returning to its original shape.
Elongation: The elongation of H62 brass is approximately 30%. This means the material can extend up to 30% of its original length before fracture, demonstrating good plasticity and toughness.
Hardness: The hardness (Brinell hardness) of H62 brass ranges from about 80 HB to 150 HB. This hardness range provides sufficient hardness while maintaining good workability, making it suitable for manufacturing various mechanical components.
Application Areas of H62 Brass
Electronics and Electrical Appliances: Used in manufacturing plugs, sockets, switches, and other electronic components.
Architectural Decoration: Used in building materials such as doors, windows, decorative panels, and handrails.
Mechanical Manufacturing: Used in producing mechanical parts like bushings, gears, and nuts.
Shipbuilding Industry: Used in manufacturing ship components such as propellers and hull decorations.
Automotive Industry: Used in manufacturing automotive parts like radiators, oil coolers, and braking systems.

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.
