Quenching and cooling performance of quenching medium was measured by KHR-A portable cooling medium performance tester.Effects of water,quenching oil,and PAG quenching medium with different concentrations on performance of electrical round aluminum rods were investigated.The sample treated by 510 ℃ ×6h solid solution and quenched in 13% PAG has uniform structure without white particle precipitation in grain.Only a small amount of white particles precipitate in grain boundary.The sample has comprehensive performance with tensile strength of 112 MPa,elongation rate of 10%,and electrical conductivity of 55.90IACS%.
