Overview - ISO 4382-2:2021 (Plain bearings, Copper alloys, Part 2)

ISO 4382-2:2021 specifies requirements for wrought copper alloys intended for use in solid plain bearings (especially bushes). The third edition (2021) updates alloy data and adds terms/definitions. It gives a limited selection of commonly used bearing alloys (for example CuSn8P, CuZn31Si1, CuZn37Mn2Al2Si, CuAl9Fe4Ni4) and defines material property data useful to designers, manufacturers and procurers of plain bearings.

Key topics and technical requirements

• Material scope: Wrought copper alloys for solid plain bearings (bushes).
• Property table: Table 1 lists chemical composition and typical/acceptance values for key properties: Brinell hardness (HBW), tensile strength, elongation, 0.2% proof stress, elastic modulus, thermal expansion, thermal conductivity and density.
• Acceptance testing: Brinell hardness is the test and acceptance value; other values are given as mean/typical design values. Hardness testing reference: ISO 4384-2.
• Designation: Standardized designation format - e.g. “Bearing metal ISO 4382 – CuSn8P – HBW 120”.
• Safety note: The document highlights lead (Pb) toxicity where present in some alloys and draws attention to regulatory/health considerations.
• Design guidance: Annex A provides practical guidance for alloy selection and the hardness of the mating shaft (bearing counterface). General guidance states the shaft hardness should be about four times the bearing alloy hardness and includes minimum shaft hardness examples (e.g., 55 HRC for certain alloys under specified conditions).

Practical applications and users

Who uses ISO 4382-2:

• Bearing designers and mechanical engineers selecting material for bushings and solid plain bearings.
• Bearing and component manufacturers specifying wrought copper alloy grades and acceptance criteria.
• Material suppliers and quality labs performing Brinell hardness and tensile testing.
• Maintenance engineers and OEMs in sectors such as industrial machinery, marine, automotive and heavy equipment where sliding components and corrosion/wear resistance are critical.

Practical benefits:

• Streamlines material selection for plain bearing applications.
• Helps match bearing alloy to operating conditions (load, sliding speed, lubrication).
• Provides a clear acceptance test (HBW) to reduce procurement disputes.
