How to distinguish the quality of copper braided wire?
1, look at the material, the manufacturer to provide raw material testing report.
2, the resistance is less than 0.01777 is T2 or above pure copper, on the contrary, it is mixed with other materials.
3, look at the report, the general regular manufacturers will provide factory inspection reports.
4, look at the appearance, the surface is smooth, no broken strands, burrs, leakage braiding phenomenon, no red and black phenomenon
5, weight, heavy products are better than light
6, the copper content of T2 copper braided wire is more than 99.95%, only at a high temperature of more than 1080 degrees to be dissolved, high temperature annealing also needs to be about 500 degrees to be softened, the profile is still copper. The copper content of other materials is only about 60%, the temperature resistance is only about 86% of pure copper, and the middle will explode with a lighter, and the section is brass.
