Overview

ASTM B240-22: Standard Specification for Zinc and Zinc-Aluminum (ZA) Alloys in Ingot Form for Foundry and Die Castings sets out requirements for commercial zinc and zinc-aluminum alloys supplied as ingots for remelting. These ingots are used in the manufacture of pressure die castings, foundry castings, and continuous cast bar stock. The standard applies to several specific alloy compositions, providing guidelines for chemical composition, quality, identification, and related testing methods. This specification ensures a uniform and reliable material supply for casting operations in various industries.

Key Topics

• Alloy Types Covered: The standard details seven key alloy compositions, including traditional Zamak alloys (Alloy 2, 3, 5, 7) and zinc-aluminum (ZA) alloys (ZA-8, ZA-12, ZA-27, and ACuZinc5). Each alloy is identified by its common name, traditional designation, ASTM code, and Unified Numbering System (UNS) designation.
• Forms and Uses: Focuses on zinc and zinc-aluminum alloy ingots for remelting to produce pressure die castings, foundry castings, and continuous cast bar stock.
• Material Quality Requirements: Ingots must be of uniform quality and reasonably free of dross, foreign matter, and surface oxide, ensuring consistent melting and casting performance.
• Chemical Composition: Strict limits are set for aluminum, magnesium, copper, iron, lead, cadmium, tin, and, where applicable, nickel. These limits are critical to maintaining purity and performance in the final cast products.
• Testing and Certification: Chemical composition is verified using suitable analytical methods, including spectrochemical analysis and reference to practices such as ASTM E536 or ISO 3815. Certification and identification marking practices are defined for traceability.
• Nomenclature Systems: Different nomenclatures (Common, Traditional, ASTM, UNS) are explained to ensure global understanding and proper specification.

Applications

The alloys covered by ASTM B240-22 are versatile and widely used in the production of cast components for multiple industries. Key applications include:

• Pressure Die Castings: Critical for automotive, electronics, hardware, and appliance sectors where dimensional stability and strength are required.
• Foundry Castings: Used in general industrial machinery and components, benefiting from the alloys’ high fluidity and castability.
• Continuous Cast Bar Stock: Ideal for further processing, machining, and prototyping.
• Permanent Mold and Sand Castings: Some alloys are also suited for specialty casting applications, supporting rapid prototyping and custom part manufacture.

The ingot compositions covered enable optimal mechanical properties, corrosion resistance, and manufacturability adapted to demanding industrial processes.

Related Standards

For comprehensive control and specification of materials, ASTM B240-22 references and aligns with several related international standards:

• ASTM B86: Specification for Zinc and Zinc-Aluminum Alloy Foundry and Die Castings – covers requirements for the finished castings produced from ingots.
• ASTM B949: General Requirements for Zinc and Zinc Alloy Products – sets out broad production and inspection rules.
• ASTM B899: Terminology Relating to Nonferrous Metals and Alloys – defines essential terms in zinc metallurgy.
• ASTM B908: Practice for the Use of Color Codes for Zinc Casting Alloy Ingot – details identification by color for safe and efficient handling.
• ISO 301: International standard for zinc alloy ingots intended for casting.
• ISO 3815-1 / ISO 3815-2: Describe analytical methods for verifying chemical composition of zinc and zinc alloys.

Practical Value

By adhering to ASTM B240-22, manufacturers and foundries benefit from:

• Consistent Material Quality: Ensures uniform ingots that support reliable casting operations.
• Global Sourcing Compatibility: Clear cross-referencing to international nomenclature and standards streamlines supply chain management.
• Regulatory and Quality Assurance: Supports safety, environmental, and performance obligations.
• Traceability and Certification: Defined marking and documentation requirements make compliance and quality verification straightforward.

Implementing ASTM B240-22 helps organizations in die casting and foundry industries meet high standards for product integrity, performance, and supply chain efficiency.
