Overview

EN 1559-6:1998 is a European standard developed by CEN that defines technical delivery conditions for zinc alloy castings. This standard serves as part 6 of the EN 1559 series, focusing specifically on additional requirements applicable to zinc alloy castings. It covers castings produced through various established foundry processes including sand casting, permanent mould casting, pressure die casting, centrifugal casting, continuous casting, and investment casting.

The standard aims to ensure consistent quality and technical specifications for zinc alloy castings delivered for use in manufacturing or industry. Importantly, it excludes raw shapes such as ingots, bars, and billets intended for further processing like remelting or extrusion.

Key Topics

• Scope of Application
  EN 1559-6 applies only to zinc alloy castings made via several casting techniques, and not to semi-finished shapes intended for subsequent reprocessing.

• Technical Delivery Conditions
  The standard specifies additional technical requirements to supplement general founding delivery conditions. These include provisions to ensure reliability and performance in zinc alloy cast components.

• Casting Methods Covered

  • Sand casting
  • Permanent mould casting
  • Pressure die casting
  • Centrifugal casting
  • Continuous casting
  • Investment casting

• Material Focus
  Zinc alloy materials are the core focus, covering a range of compositions used in industrial castings.

• Exclusions
  The standard explicitly excludes ingots, bars, billets, or other semi-finished products intended for further machining or shaping.

Applications

EN 1559-6:1998 is highly relevant for manufacturers, suppliers, and quality assurance professionals involved in the production and delivery of zinc alloy castings. Typical practical applications include:

• Automotive components requiring zinc alloy cast parts
• Electrical and electronic housings
• Decorative fittings and hardware
• Industrial machinery parts that need corrosion resistance and dimensional accuracy
• Precision mechanical components produced via investment or pressure die casting

By adhering to EN 1559-6, producers can guarantee consistent mechanical properties, dimensional tolerances, and surface quality, facilitating supply chain reliability and customer satisfaction.

Related Standards

• EN 1559-1 to EN 1559-5 – These parts address technical conditions of delivery for castings made from other non-ferrous alloys such as aluminum, copper, and tin alloys.
• EN ISO 8062 – Provides general dimensional tolerances for castings applicable to zinc alloys.
• EN 1706 – Specifies zinc alloy chemical compositions for castings, complementing the requirements in EN 1559-6.
• EN 12844 – Addresses powder metallurgy, often related to finishing or secondary processes of metal castings.

---

By following the additional requirements defined in EN 1559-6:1998, foundries specializing in zinc alloy castings can enhance product quality and ensure compliance with European technical delivery standards. This boosts the reliability and marketability of zinc alloy components across multiple industrial sectors.
