Overview
ASTM B465-20, titled Standard Specification for Copper-Iron Alloy Plate, Sheet, Strip, and Rolled Bar, defines the requirements and quality standards for various wrought copper-iron alloy products. Developed by ASTM International, this specification covers plates, sheets, strips, and rolled bars manufactured from copper-iron alloys with UNS numbers C19200, C19210, C19400, C19500, C19700, and C19720. The document ensures consistent product quality by specifying permissible composition ranges, mechanical and electrical property requirements, manufacturing methods, and testing procedures. These copper-iron alloys are widely used in industries that demand high conductivity, mechanical strength, and uniformity in product dimensions.
Key Topics
- Covered Alloys: UNS C19200, C19210, C19400, C19500, C19700, and C19720.
- Product Forms: Plate, sheet, strip, and rolled bar.
- Manufacturing Methods: Products are made from cast bar, cake, or slab, and undergo hot or cold working and annealing to obtain a uniform wrought structure.
- Tempers Available: Including O60 (soft annealed), O61 (annealed), O50 (light annealed), O82 (annealed to temper, ½ hard), H01 (¼ hard), H02 (½ hard), H03 (¾ hard), H04 (hard), H06 (extra hard), HR02 (½ hard), HR04 (hard), H08 (spring), H10 (extra spring), and H14 (super spring).
- Dimensional Requirements: Mass, thickness, length, width, straightness, and type of edge are specified according to referenced tables in ASTM B248.
- Property Requirements:
- Mechanical: Minimum tensile strength and Rockwell hardness values for each alloy and temper.
- Electrical: Mass resistivity and equivalent conductivity, with requirements varying by alloy and temper.
- Chemical: Limits for copper, iron, phosphorus, zinc, lead, tin, cobalt, aluminum, magnesium, nickel, and manganese.
- Grain Size: For annealed tempers, full recrystallization is required.
- Testing and Quality Control: Products must meet test procedures for dimensional tolerances, properties, and chemical analysis as defined in referenced ASTM methods.
Applications
Copper-iron alloy products manufactured according to ASTM B465-20 are recognized for their excellent electrical conductivity, strength, and corrosion resistance. Common applications include:
- Electrical and electronic components - such as connector parts, terminal strips, busbars, and leadframes, where conductivity and mechanical strength are essential.
- Automotive parts - especially for components that require reliable performance in harsh environments.
- Industrial machinery - including gears, springs, and wear plates, where toughness and resistance to deformation are important.
- Aerospace and defense - for specialized brackets, hardware, and conductive strips meeting high-performance requirements.
Engineers and manufacturers rely on this standard to guarantee product quality, compatibility, and regulatory compliance in critical applications.

7.2 These composition limits do not preclude the presence of other elements. By agreement between the manufacturer and
purchaser, limits may be established and analysis required for unnamed elements.
7.3 For alloys in which copper is listed as “remainder,” copper is the difference between the sum of results of all elements
determined and 100 %.
7.3 For alloys in which copper is listed as “remainder,” copper is the difference between the sum of results of all elements
determined and 100 %. When all elements in Table 1 are determined, the sum of results shall be 99.8 % min, except for C19720
which shall be 99.5 % min.
8. Temper
8.1 The standard tempers for products described in this specification are given in Tables 2 and 3.
8.1.1 Cold-rolled tempers H01 to H14.
8.1.2 Annealed tempers O50, O60, O61, or O82.
8.1.3 Cold-worked and stress-relieved tempers HR02 to HR06.
NOTE 2—The purchaser should confer with the manufacturer or supplier for the availability of product in a specific alloy, temper, and form, since all
tempers are subject to manufacturing limitations.
NOTE 3—Properties of special tempers not listed in this specification are subject to agreement between the manufacturer and purchaser.
9. Grain Size for Annealed Tempers
9.1 Grain Size—No grain size requirements have been established for tempers O50, O60, and O61; however, the product material
shall be fully recrystallized when examined in accordance with Test Methods E112.
10. Physical Property Requirements
10.1 Electrical Resistivity Requirement:
10.1.1 The product furnished shall conform to the electrical mass resistivity requirement prescribed in Table 2 when tested in
accordance with Test Method B193.
10.1.2 Products produced in temper O60 from Copper Alloy UNS No. C19400 are not required to conform to the electrical mass
resistivity requirements of Table 2.
