ASTM B584-22

Overview

ASTM B584-22, titled Standard Specification for Copper Alloy Sand Castings for General Applications, defines critical requirements for the manufacture, composition, and mechanical properties of sand-cast copper alloy components. Issued by ASTM International, this standard ensures the production of copper alloy castings that meet specified quality, mechanical, and compositional requirements, making it an essential document for manufacturers, suppliers, and end-users involved with copper alloy sand castings.

The standard applies to a broad range of copper alloys (brass, bronze, silicon bronze, and others) designed for general use. Key features include controls on alloy composition, mechanical property testing, certification, and guidelines for product marking and ordering.

Key Topics

• Scope

  • Covers sand castings in copper alloys for general applications.
  • Incorporates nominal composition requirements for each alloy.
  • Specifies that castings may be produced ahead of time and supplied from stock.
  • Values are stated in inch-pound units with SI equivalents provided for reference.

• Mechanical Properties

  • Requires testing for tensile strength, yield strength, and elongation.
  • Specifies that properties must meet requirements listed for each copper alloy.
  • Test procedures must follow referenced ASTM standards.

• Chemical Composition

  • Mandates conformity to specified chemical composition limits for copper, tin, lead, zinc, and other elements depending on alloy type.
  • Allows analysis of residual elements if specified.

• Manufacturing and Quality Assurance

  • Castings must not be repaired, plugged, welded, or burned in unless approved by the purchaser.
  • Requires general quality certification when supplying from stock; traceability requirements apply for certain uses.
  • Inspection, marking, and documentation guidelines are provided for quality assurance.

• Purchasing and Ordering

  • Outlines information to include in orders (spec number, quantity, alloy designation, pattern or drawing number, condition, etc.).
  • Lists available options such as pressure tests, residual elements analysis, and certification requirements.

Applications

ASTM B584-22 is widely used across industries where copper alloy sand castings are essential for reliable performance and safety. Its typical applications include:

• Machinery and Equipment

  • Components for general engineering, pumps, valves, and industrial machinery.

• Plumbing and Fluid Handling

  • Fittings, connectors, and parts used in fluid conveyance systems.

• Marine and Architectural

  • Cast elements exposed to corrosive environments, such as marine hardware and architectural bronze.

• Construction and Utilities

  • Sand cast copper alloy parts for bridges, turntables, pressure vessels, and other infrastructure.

By adhering to ASTM B584-22, manufacturers and buyers ensure that copper alloy sand castings offer reliable mechanical properties, chemical stability, and general durability required in these demanding applications.
