Homogenizing Annealing of Aluminum Alloy Cable

The microstructure and properties of aluminum alloy cable with different homogenizing annealing process were studied. The results show that the microstructure and properties of aluminum alloy are improved by homogenizing annealing at450 ℃ due to non-equilibrium phase solid solution gradually. The optimum homogenizing annealing process of cable with aluminum alloy is keeping the alloys annealed at 450 ℃for 24 h.
