ASTM B100-20

Standard Specification for Wrought Copper-Alloy Bearing and Expansion Plates and Sheets for Bridge and Other Structural Use

ABSTRACT
This specification covers the standard for wrought copper-alloy bearing plate and bearing sheets intended for use in bridges and other structures. The plates and sheets are also proposed for use as fixed or expansion bearings where motion is slow and intermittent. Specimens shall be manufactured by hot working, cold working, and annealing. Specimens shall adhere to mechanical properties such as tensile strength, yield strength, and elongation. The plates and sheets shall be subjected to tensile, hardness, and compression tests. The specimens shall also undergo chemical analysis. When the specimens fail to conform to the specification, a retest shall be permitted.
SCOPE
1.1 This specification establishes the requirements for wrought copper-alloy bearing plate and bearing sheets for application in bridges and other structures. Specifically, the plates and sheets are to be used for fixed or expansion bearings where the motion is slow and intermittent with pressures not exceeding 3 ksi (20 MPa).  
1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.2.1 Exception—Values given in inch-pound units are the standard except for grain size, which is stated in SI units.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM B100-20: Standard Specification for Wrought Copper-Alloy Bearing and Expansion Plates and Sheets for Bridge and Other Structural Use provides a comprehensive framework for the manufacture, testing, and use of copper-alloy plates and sheets intended as bearing elements in bridges and other structures. Developed by ASTM International, this standard is integral for ensuring reliable performance and structural integrity where copper alloys are used as fixed or expansion bearings exposed to slow, intermittent motion.

Designed for both inch-pound and informational SI units, ASTM B100-20 is referenced globally for structural engineering projects requiring high-quality bearing materials that can withstand demanding conditions.

Key Topics

• Scope of Use
  The standard specifies wrought copper-alloy plates and sheets for fixed or expansion bearing use in bridges and structural applications, particularly where movements are slow and pressures do not exceed 3 ksi (20 MPa).

• Material Requirements
  The standard covers copper alloys such as UNS No. C51000, C51100, C61300, C61400, and C65500, with defined limits for elements including tin, silicon, aluminum, iron, manganese, zinc, lead, and nickel.

• Manufacturing Processes
  Plates and sheets are required to be produced by hot working, cold working, and annealing to ensure a uniform and reliable microstructure suitable for bearing applications.

• Mechanical Properties
  Specified mechanical properties include minimum tensile strength, elongation, yield strength, and hardness as determined by established ASTM test methods.

• Testing and Quality Control
  Products must undergo rigorous testing:

  • Tensile tests according to ASTM E8/E8M
  • Compression tests as per ASTM E9
  • Hardness tests per ASTM E10 (Brinell) and E18 (Rockwell)
  • Chemical analysis to ensure compliance with alloy composition requirements

• Dimensional Tolerances
  Detailed tolerances for thickness, width, length, and weight are outlined to ensure conformity and interchangeability in structural installations.

Applications

Wrought copper-alloy bearing plates and sheets made to ASTM B100-20 are crucial components in a wide variety of structural engineering projects, particularly in:

• Bridges
  Used as fixed or expansion bearings, these copper-alloy elements absorb movement and loads, enhancing durability and reducing maintenance needs.

• Structural Bearings
  Ideal for use in other structures requiring slow, intermittent movement, copper-alloy bearings accommodate slight shifts due to loads, temperature changes, or settling without compromising structural performance.

• Civil Infrastructure
  Beyond bridges, any civil engineering application that demands corrosion-resistant, high-strength bearings-such as tunnels and large buildings-can benefit from these specified products.

The standard's emphasis on quality, mechanical properties, and exact dimensions ensures that these copper-alloy components perform reliably in critical load-bearing roles.

Related Standards

ASTM B100-20 references several key standards and practices within the copper and copper alloys field for terminology, testing, and general requirements, including:

• ASTM B248: General Requirements for Wrought Copper and Copper-Alloy Plate, Sheet, Strip, and Rolled Bar
• ASTM B846: Terminology for Copper and Copper Alloys
• ASTM E8/E8M: Test Methods for Tension Testing of Metallic Materials
• ASTM E9: Test Methods of Compression Testing of Metallic Materials at Room Temperature
• ASTM E10: Brinell Hardness of Metallic Materials
• ASTM E18: Rockwell Hardness of Metallic Materials
• ASTM E478: Chemical Analysis of Copper Alloys

Adherence to ASTM B100-20 ensures structural reliability, safety, and compliance with globally recognized engineering standards for copper-alloy bearing applications.

When the product is for subsequent welding applications and is so specified by the purchaser, chromium, cadmium, zirconium, and zinc shall each be 0.05 % max.
6.2 Manufacture:
6.2.1 The product shall be manufactured by hot working, cold working, and annealing processes as to produce a uniform
wrought structure in the finished product.
6.2.2 The product shall be hot or cold worked to the finished size and subsequently annealed, when required, to meet the temper
properties specified.
7. Chemical Composition
7.1 The material shall conform to the chemical composition requirements prescribed in Table 2 for the Copper Alloy UNS No.
designation specified in the ordering information.
7.2 These compositionalcomposition limits do not preclude the presence of other elements. By agreement between the
manufacturer and the purchaser, limits may be established, and analysis required for unnamed elements.
7.3 Copper, given as the remainder, may be taken as the For alloys in which copper is listed as “remainder,” copper is the
difference between the sum of results of all elements analyzeddetermined and 100 %.
7.4 When all elements listed in Table 2 for the specified Copper Alloy UNS No. designation are determined, the sum of results
shall be 99.5 % min except for C61300 which shall be 99.8 %.
8. Temper
8.1 The temper of product furnished to this specification, and as defined in Practice B601, shall be as follows:
UNS Alloy No. Temper
C51000 H03 ( ⁄4 hard)
C51100 H03 ( ⁄4 hard)
C65500 H01 ( ⁄4 hard)
C61300 M20 (as hot rolled) or 061 (annealed)
C61400 M20 (as hot rolled) or 061 (annealed)
9. Mechanical Property Requirements
