| Abstract: | The significance to improve the conductivity of aluminium conductors is described. The newly developed boron containing aluminium conductors have reched the internationally advanced level with the technical data as follows: resistivity ρ=(2.73～2.76)×10-8 Ω·m, the tensile strength of single wire σb=165～185 MPa. The manufactureing technology for the high conductivity boron containing aluminium conductors for electric puroposes was presented in terms of optimization of chemical components, filtering of the liquid aluminium and recovery treatment. The future applications of this new conductors were envisaged. |
