Brass Alloy Bushing H62 Material

RoHS Compliant | Lead Content Below 0.1%

Overview of H62 Brass Alloy Bushing Material

H62 brass alloy bushing is a low-lead copper-zinc alloy solution widely used for structural, positioning, and guiding applications in industrial machinery.
Manufactured according to GB/T 5231, H62 contains approximately 62% copper with lead content ≤ 0.08%, making it fully RoHS compliant without exemption.

Although often referred to as a bronze bushing in engineering practice, H62 is technically a brass (Cu-Zn) alloy, offering an excellent balance of strength, formability, cost efficiency, and environmental compliance.

Chemical Composition of H62 Brass

• Copper (Cu): 60.5 – 63.5%

• Zinc (Zn): Balance

• Lead (Pb): ≤ 0.08%

• RoHS Compliance: Pb < 0.1% (homogeneous material)

This low-lead composition allows H62 bushings to meet strict environmental requirements for EU, US, and global export markets.

Key Material Characteristics

• Good mechanical strength and rigidity

• Excellent machinability for precision bushings

• Stable dimensional performance under load

• Cost-effective alternative to tin bronze bushings

• Suitable for grease or oil lubrication

• Environmentally friendly, RoHS compliant

⚠ H62 is not a self-lubricating material and is not recommended for high-PV or dry-running applications.

Typical Mechanical Equipment Applications

Structural & Positioning Bushings

H62 brass alloy bushings are commonly used in:

• Gearboxes and reducers (support sleeves)

• Motor end covers

• Equipment frames and shaft positioning components

These applications involve low speed, moderate load, and benefit from H62’s strength and dimensional stability.

Pivot, Hinged & Oscillating Mechanisms

Typical uses include:

• Packaging machinery linkages

• Conveyor tension arms

• Industrial covers and swing arms

H62 performs well in low-speed oscillating motion with proper lubrication.

Low-Speed Guiding Bushings

Suitable for:

• Simple linear guides

• Manual adjustment mechanisms

• Light-duty tooling and fixtures

Recommended when cost control and RoHS compliance are more critical than extreme wear resistance.

Electrical & General Industrial Equipment

Widely applied in:

• Small motors and fans

• Home appliances

• Automation components

H62 is often selected where Pb < 0.1% is mandatory.

When H62 Is Not Recommended

H62 brass alloy bushings are not suitable for:

• High-speed rotating shafts

• High PV or heavy shock loads

• Long-term dry-running conditions

• Maintenance-free bearing positions

For these conditions, CuSn8 bronze, PTFE composite bushings, or self-lubricating solutions are recommended.

Typical Material Selection Solutions

Standard Solution

• Material: H62 brass bushing

• Lubrication: Grease or oil

• Application: Structural and guiding functions

Enhanced Design

• H62 bushing with oil grooves or lubrication holes

• Extended service life under moderate wear conditions

Alternative Upgrades

• CuSn8 / CuSn8Ni bronze for higher wear resistance

• PTFE composite bushings for maintenance-free operation

• Lead-free EcoBrass for premium RoHS applications

International Material Reference

• GB: H62

• EN: CuZn38 / CW612N-type (performance equivalent)

• ASTM / UNS: C28000

• JIS: C2801

Note: Actual lead content is controlled according to H62 specification to ensure RoHS compliance.

Summary

H62 brass alloy bushing material is an ideal choice for low-speed, moderate-load mechanical applications requiring RoHS compliance and low lead content. It provides a reliable, economical solution for structural and guiding bushings while meeting global environmental standards.

Overview

H62 brass alloy bushings are widely used for structural, positioning, and guiding applications in industrial machinery.
This low-lead copper-zinc alloy offers excellent machinability, moderate strength, and RoHS compliance (Pb ≤ 0.08%).

For international projects, H62 can be referenced to EN1982 and ASTM / UNS material codes for design, procurement, and technical documentation purposes.

1️⃣ EN1982 (European Standard Brass)

⚠ Note: For strict RoHS compliance (<0.1% Pb), select low-lead EN1982 grades or provide material certificates.

2️⃣ ASTM / UNS (US Standard Brass)

⚠ Note: Actual lead content should be confirmed with a Certificate of Analysis (CoA) to guarantee RoHS compliance.
