Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nickel content 5%+
Nickel silvers require separate classification when Ni exceeds threshold.
If ferrous contamination >50%
Significant iron content shifts to iron/steel alloy classification.
If wire rod precursor form
Pre-formed wire rod shapes classify under wire production headings.

Import Tips & Compliance
• Submit MIL-STD alloy specifications matching imported composition
• Ensure slab dimensions exceed unwrought minimums (typically >5kg)
• Avoid mixing with bronze alloys during storage to prevent cross-contamination
