Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Intergranular corrosion
Cause: Presence of impurities at grain boundaries, improper heat treatment, or exposure to corrosive environments leading to preferential attack along grain boundaries
Stress corrosion cracking
Cause: Combination of tensile stress (residual or applied) and corrosive environment, particularly chloride-containing solutions, causing crack propagation
Maintenance Indicators
  • Visible white powdery deposits or localized pitting on ingot surfaces indicating active corrosion
  • Audible cracking or popping sounds during thermal cycling or handling suggesting internal stress relief or crack propagation
Engineering Tips
  • Implement strict environmental controls including humidity regulation (<40% RH) and chloride-free storage to prevent corrosion initiation
  • Apply controlled heating/cooling rates during processing (max 100°C/hour) and stress-relief annealing at 250-300°C to minimize residual stresses

Compliance & Manufacturing Standards

Reference Standards
ISO 209-1:2019 (Wrought aluminium and aluminium alloys) ASTM B179-18 (Standard Specification for Aluminum Alloys in Ingot Form) EN 576:2003 (Aluminium and aluminium alloys - Unalloyed aluminium ingots for remelting)
Manufacturing Precision
  • Chemical Composition: +/-0.05% for major alloying elements
  • Ingot Dimensions: Length +/-10mm, Width/Thickness +/-5mm
Quality Inspection
  • Optical Emission Spectrometry (OES) for chemical composition
  • Ultrasonic Testing for internal defects
