Aluminium Wire Sizes
Aluminium wires are available in a wide range of diameters to suit diverse applications:
- Fine Wires: 0.015 mm to 0.5 mm
- Medium Wires: 0.5 mm to 3.0 mm
- Thick Wires: 3.0 mm to 200 mm
Note: Specific sizes may vary based on the manufacturer and alloy grade.
Aluminium Grades & Mechanical Properties
Aluminium wires are manufactured in various grades, each with specific chemical compositions and mechanical properties:
| Grade | Purity (%) | Temper | Applications |
