1. Aluminum wire manufacturing process
- metallurgical manufacturing and forming.
2.Aluminum wire Surface properties
- The surface of the thermal spray aluminum wires shall be smooth and free of corrosion products slivers and splits,shrinkholes,splices and scales ,damages as well as neckings,welds and laps .
3.Chemical Composition
- Aluminum wire shall conform to the requirements prescribed in ISO 14919:2001
| Symbol | Al % | Si % | Fe % | Ti % | Cu % | Zn % | Mn % | particular % | total |
| Al99.5 | min.99.5 | ≤0.3 | ≤0.4 | ≤0.05 | ≤0.05 | ≤0.07 | ≤0.05 | ≤0.03 | ≤0.5 |
4.Dimensions and Permissible Variations
Aluminum wire shall conform to the sizes, tolerances listed in ISO 14919: 2001
| Site (mm) | Tolerance(mm) |
| 1.6 | +0 ; -0.05 |
| 1.62 | +0 ; -0.05 |
| 2.0 | +0 ; -0.06 |
| 2.3 | +0 ; -0.06 |
| 2.4 | +0 ; -0.06 |
| 2.5 | +0 ; -0.06 |
| 3.0 | +0 ; -0.07 |
| 3.17 | +0 ; -0.07 |
| 3.48 | +0 ; -0.07 |
| 4.76 | +0 ; -0.07 |
5.Size(s) of Packaging
- the wire shall be a continuous length per spool, coil, or drum. Splices or welds are permitted, provided that they do not interfere with the thermal spray equipment or coating process.
- If special packaging is required, it shall be negotiated between the supplier and the purchaser.
| Packaging | Size | Weight |
| Coil | Outer diameter:420mm, Inner Diameter:290mm, Outer width:70mm | 25kg/Coil |
| Reel/spool | Outer diameter:270/300mm, Hole diameter:50mm, Outer width:105 mm | 10-20kg/reel |
| Drum | Outer diameter:570mm Height:380mm | 30-50kg/drum |
| Drum | Outer diameter:570mm Height:740mm | 60-80kg/drum |
6. Purpose
Aluminum wire is used in oxy-fuel and arc thermal spray equipment to deposit zinc coatings by thermal spraying (metallization) for corrosion protection of steel and iron.
Concrete application：
- Wind turbines, Hub,Base,Bearing seat,
- Capacitor.
- Heat exchanger.
- Cast pipe.
- Bridges.
- Locks & dams
- Above ground storage tanks
- Light poles
