16. CRITICAL WARNINGS AND BEST PRACTICES
CRITICAL WARNINGS:
-
High Purity: Aluminum feed wire is produced with minimum 99.5% purity. Lower purity may cause unwanted impurities in the final alloy.
-
Diameter Precision: Diameter tolerance is critical in automatic feeding systems. Ø9.5 mm and Ø12.5 mm are standard diameters with ±0.1 mm tolerance.
-
Quality and Origin: Purity and diameter precision in wire form are critical for automatic dosing and alloy accuracy. Trader-sourced products may show variability in origin and packaging.
-
Oxidation: Oxidizes in oxidizing atmospheres at high temperatures; inert atmosphere or vacuum is required for melting operations.
-
Acid Reactivity: Reacts with strong acids releasing hydrogen gas.
BEST PRACTICE RECOMMENDATIONS:
-
Storage:
-
Store in a cool, dry, and well-ventilated area.
-
Store in original packaging, moisture-free environment.
-
Keep away from acids and oxidizing agents.
-
Store at room temperature (15-25°C).
-
-
Handling:
-
Use in accordance with manufacturer's instructions in automatic wire feeding systems.
-
Handle carefully to prevent wire breakage or deformation.
-
Use vacuum or inert atmosphere (Ar, N₂) for melting operations.
-
Wash hands thoroughly after handling.
-
-
Waste Management:
-
Dispose of in accordance with local regulations.
-
Do not discharge into water sources.
-
For large quantities, aluminum recovery should be considered.
