Overview

ASTM B130-19: Standard Specification for Commercial Bronze Strip for Bullet Jackets sets forth requirements for commercial bronze strip used in the manufacture of bullet jacket cups and ammunition components. Specifically, this standard specifies material produced from copper alloy UNS No. C22000. It addresses critical manufacturing aspects such as hot and cold working, annealing, and uniform wrought structure to ensure the bronze strip meets demanding performance and quality criteria. The standard includes mandates for mechanical and chemical property testing, dimensional tolerances, and inspection, making it essential for ammunition manufacturers and material suppliers involved in production of bullet jackets and related components.

Key Topics

• Material Requirements: The bronze strip must be made from copper alloy UNS No. C22000, ensuring a consistent and reliable base material for bullet jacket cups.
• Manufacturing Processes: The strip is produced using a combination of hot working, cold working, and annealing techniques to achieve a uniform wrought structure suitable for forming operations.
• Mechanical and Chemical Testing:
  • Tensile Strength: The product must undergo a tension test to confirm adequate mechanical properties as outlined in the standard.
  • Rockwell Hardness: A Rockwell hardness test is performed to assess conformity with required hardness ranges.
  • Grain Size: Purchasers may specify grain size, with grain size testing required if stipulated.
  • Chemical Composition: Strict limits are set for copper, zinc, lead, iron, and bismuth, ensuring controlled alloy composition.
• Dimensional Tolerances: Precise thickness, width, length, and straightness tolerances are specified. These tolerances ensure consistent processing and reliable performance during bullet and ammunition manufacturing.
• Inspection and Certification: The standard covers detailed procedures for sampling, inspection, retesting, and rejection criteria to meet quality control requirements.
• Packaging and Marking: Guidelines for packaging, marking, and traceability are included to ensure correct delivery and identification.

Applications

ASTM B130-19 is widely adopted in the ammunition industry for the fabrication of bullet jacket cups and similar components requiring high-performance, work-hardened bronze strip. The use of UNS C22000 commercial bronze provides a balance of formability, strength, and corrosion resistance-essential for the demanding environments in which ammunition is manufactured and used.

Typical practical applications include:

• Production of bullet jackets for small arms and commercial ammunition
• Manufacture of ammunition components such as base cups and other strip-formed parts
• Supply chains for military, law enforcement, and civilian ammunition manufacturers

Manufacturers and suppliers who comply with ASTM B130-19 benefit by ensuring their materials are compatible with a broad range of forming and assembly processes, and by providing assurance of consistent quality to customers.

Related Standards

To ensure comprehensive compliance and quality, users of ASTM B130-19 should also be aware of these related standards:

• ASTM B248/B248M: General requirements for wrought copper and copper-alloy plate, sheet, strip, and rolled bar.
• ASTM B601: Classification for temper designations for copper and copper alloys.
• ASTM B846: Terminology for copper and copper alloys, important for specification consistency.
• ASTM E3, E8/E8M, E18: Guides and methods for metallographic preparation, tension testing, and Rockwell hardness testing of metallic materials.
• ASTM E29: Practice for using significant digits in test data to determine conformance.
• ASTM E112: Methods for determining average grain size.
• ASTM E255, E478, E527: Practices for sampling and chemical analysis relevant to copper alloys.

By adhering to ASTM B130-19 and the associated referenced standards, manufacturers and suppliers maintain high standards for bullet jacket material quality, enhancing safety, performance, and market acceptance across the ammunition sector.

4.1.10 When material is purchased for agencies of the U.S. government, see Section 11.
4.2 The following options are available but may not be included unless specified at the time of placing of the order, when
required:
4.2.1 Grain size of annealed temper (Section 8),
4.2.2 Heat identification or traceability details,
4.2.3 Certification,
4.2.4 Test report, and
4.2.5 If product is purchased for agencies of the U.S. Government, see Section 11 for additional information, if specified.
5. Materials and Manufacture
5.1 Material:
5.1.1 The material of manufacture shall be a form (cast bar, cake, slab, et cetera) etc.) of Copper Alloy UNS No. C22000 of
such purity or soundness as to be suitable for processing into products prescribed herein.
5.1.2 When specified in the contract or purchase order,order that heat identification or traceability is required, the purchaser shall
specify the details desired.
NOTE 1—Because of the discontinuous nature of the processing of castings into wrought products, it is not always practical to identify a specific casting
analysis with a specific quantity of finished material.

Lead, max 0.05
Iron, max 0.05
Bismuth, max 0.006

B130 − 19
5.2 Manufacture:
5.2.1 The product shall be manufactured by such hot working, cold working, and annealing processes as to produce a uniform
wrought structure in the finished product.
5.2.2 The product shall be hot or cold worked to the finished size and subsequently annealed, when required, to meet the temper
properties specified in the ordering information.
5.2.3 Edges—Slit edges shall be furnished unless otherwise specified in the contract or purchase order.
6. Chemical Composition
6.1 The productmaterial shall conform to the composition prescribedrequirements in Table 1.
6.2 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.
6.3 Either copper or zinc may be taken as the difference between the sum of all other elements analyzeddetermined and 100 %.
Copper, when determined by difference, must conform to the requirements of Table 1. When all elements in Table 1 are analyzed,
their sum determined, the sum of the results shall be 99.8 % min.
7. Temper
7.1 The standard tempers for products described in this specification are given in Tables 2-4:
7.1.1 Cold-Rolled Tempers—H01 to H10.
7.1.2 Annealed Tempers—OS015 to OS035.
8. Grain Size of Annealed Tempers
8.1 In addition to the tensile properties prescribed in Table 4 for strip, grain size may also be specified by the purchaser. When
grain size is specified, the average grain size of the annealed strip shall be within the limits prescribed in Table 3. At a magnification
of 75×, the average grain size of selected areas 79.8 mm in diameter of each of two samples of annealed strip shall be determined
on a plane parallel to the surface of the strip.
9. Mechanical Property Requirements
9.1 Tensile Strength of Rolled Tempers—The tension test shall be the standard test for all tempers of cold-rolled strip, and the
acceptance or rejection.rejection, based upon mechanical properties, shall depend only on the tensile strength which shall conform
to the requirements prescribed in Table 2. Tension test specimens shall be taken so the longitudinal axis is parallel to the direction
of rolling.
9.2 Rockwell Hardness of Rolled Tempers—Since a Rockwell hardness test offers a quick and convenient method of checking
commercial bronze for general conformity to the requirements for tensile strength, the approximate Rockwell hardness values for
each of the cold-rolled tempers are given in Table 2 for general information and assistance in testing.
9.3 Tensile Strength of Annealed Tempers—The tension test shall be the standard test for all tempers of annealed strip, and the
acceptance or rejection, based upon mechanical properties, shall depend only on the tensile strength which shall conform to the
requirements prescribed in Table 4. Tension test specimens shall be taken so that the longitudinal axis is parallel to the direction
of rolling. When grain size is specified by the purchaser (8.1), the acceptance and rejection shall be based on both the grain size
(Table 3) and tensile strength (Table 4).
10. Dimensions, Mass, and Permissible Variations
10.1 Thickness—The standard method of specifying thickness shall be in decimal fractions of an inch. The tolerances shall be
as shown in Table 5.
