A8 Aluminum Ingot – High-Purity (99.8%) Aluminum for Premium Applications

Overview

The A8 Aluminum Ingot is a high-purity aluminum product with a minimum 99.8% aluminum content, offering superior quality compared to A7 (99.7%) while remaining cost-effective for applications that demand high purity without the premium of ultra-high-grade A9 (99.9%).

Its excellent corrosion resistance, electrical conductivity, and lightweight properties make it ideal for precision manufacturing, advanced alloys, and specialized industrial uses.

Applications

✔ Electronics – High-purity wiring, conductors, semiconductor components
✔ Aerospace – Lightweight, high-strength aircraft & spacecraft parts
✔ Automotive – Premium components requiring corrosion resistance
✔ Alloying – Base material for high-performance alloys (e.g., 1xxx series)
✔ Packaging – High-quality foils for food, pharmaceuticals, and cosmetics
✔ Chemical Industry – Catalysts and high-purity aluminum compounds

Manufacturing Process

  1. Bauxite Refining (Bayer Process) – Conversion of bauxite to alumina.

  2. Electrolytic Reduction (Hall-Héroult Process) – Alumina is reduced to molten aluminum under strict impurity control.

  3. Casting – Molten aluminum is cast into ingots under controlled conditions.

  4. Quality Control – Ingots are tested for composition and surface quality to meet A8 standards (e.g., GB/T 1196-2002, ASTM, EN AW-1080A, AA 1080).

Standards & Certifications

  • Compliant with ISO 9001, RoHS, ASTM, JIS, GB, EN

  • Equivalent to EN AW-1080A (Europe) / AA 1080 (USA)

Packaging & Shipping

  • Packing: 20–25 kg per ingot, bundled in 1–1.25 MT (40–54 ingots) with steel/iron straps on wooden pallets.

  • Container Load: ~25 MT per 20-foot container.

  • Strap Weight: Adds ~5–15 kg per bundle.
