Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not round cross-section
Non-round piano wire (e.g., shaped) falls under 'other' shapes.
If pre-strung in pianos
Wire assembled in instruments becomes musical instrument parts.
If alloy angle/tool steel
Specialty alloy versions for custom instruments use alloy headings.

Import Tips & Compliance
• Specify exact tensile strength (e.g
• 2800 MPa) matching heat treatment grade
• Distinguish from guitar string wire which may have different carbon specs
• Precision diameter tolerance critical; variances affect musical instrument duty
