Copper (aluminum) flat wire
Product description:
Electrical flat copper wire is a wire that is extruded or drawn from an oxygen-free copper rod through a mold of a certain specification. The electrical flat copper wire can be used as a finished product or an intermediate product. The electrical aluminum flat wire is made by an oil-free electrician. Round aluminum rod is continuously extruded by a certain specification mold. The electrical aluminum flat wire produced by extrusion has the advantages of smooth conductor surface, no burrs, uniform size and tensile strength, and low resistivity. It can be used as a finished product. It can also be an intermediate product, which is widely used in windings of motors, transformers, welding machines and other similar electrical equipment.
Executive standard:GB5584.2-2009;GB5584.3-2009
material:
The rectangular copper wire should meet the requirements of GB5584.3-2009, and the resistivity at 20°C should not be greater than 0.017241Ωmm2/m
The aluminum flat wire should meet the requirements of GB5584.3-2009, and the resistivity at 20°C should not be greater than 0.0280Ωmm2/m
The tensile strength and elongation of the copper (aluminum) rectangular wire should meet the requirements of the following table:

| 3.15＜a≤5.60 | ±0.05 | 3.15＜b≤6.30 | ±0.05 |
| 6.30＜b≤12.50 | ±0.07 | ||
| 12.50＜b≤16.00 | ±0.10 |
The R angle of the copper (aluminum) rectangular wire should meet the requirements of the following table:
| Nominal size/mm | Fillet radius | Nominal size/mm | Fillet radius | ||
| Nominal | deviation | Nominal | deviation | ||
| a≤1.00 | a/2 | ±25% | 2.44＜a≤3.55 | 0.80 | ±25% |
| 1.00＜a≤1.60 | 0.5a | 3.55＜a≤5.60 | 1.00 | ||
| 1.60＜a≤2.44 | 0.65b | ||||
| If the manufacturer and the user agree through negotiation, the rounded corner radius of a flat wire with a width larger than 4..75mm can be: ①semi-circle; ②0.80mmb If agreed between the manufacturer and the user, the fillet radius of the copper strip can be a/2 |
