Definitions

the elasticity is mainly related to the yield strength/tensile strength ratio and the modulus of elasticity of the material.
the yield strength of the material is absolutely lower than the tensile strength. If the applied stress exceeds the yield strength, plastic deformation occurs. If the tensile strength is higher, the amount of plastic deformation endurable for the material before fracture failure is larger; if the yield strength is higher, the maximum endurable elastic deformation is larger; and, if the modulus of elasticity is larger, a larger resilience force can be obtained under a same elastic displacement. Therefore, for a same kind of material, to allow the material to have better elasticity, it is required to obtain a yield strength/tensile strength and a modulus of elasticity as high as possible.
Method 5 Preparing materials ⁇ smelting ⁇ horizontal continuous casting/ continuous up casting ⁇ solid solution treatment ⁇ primary inverse drawing -first- stage aging heat treatment- secondary inverse drawing - second- stage aging heat treatment ⁇ continuous drawing and aging heat treatment ⁇ packaging.
the solid solution formed by solving the cobalt-silicon compound into lattices is less stable, and it is difficult to form a supersaturated solid solution under the online solid solution conditions. Accordingly, the conditions for dispersed precipitation of the cobalt-silicon phase cannot be satisfied, the conductivity of the material is low, and the modulus of elasticity and the mechanical property are improved limitedly, so that the application requirements cannot be satisfied.
the mass relation and the atomic ratio of Cu and Zn are within the scope of the claims.
the Table 2 mainly indicates the influence of different changes in content of two alloy elements Co and Si on various basic performances of the material. It can be seen from the data in Embodiments 15 to 22 and comparison examples 13 and 14 that, in the present invention, the content of Co needs to be between 0.01% and 3%, and the content of silicon needs to be between 0.01% and 0.5%. If the content of any element is beyond this range, the comprehensive performance of the material cannot satisfy the requirements.
This scheme is used for indicating the influence of the proportion of phases in the microstructure of the copper alloy on the material performance, and includes Embodiments 23 to 32 (which are provided for illustrative purposes only and do not form part of the claimed invention), as shown in Fig. 3 .
Materials are prepared according to the designed composition.
the raw materials comprise electrolytic copper, 0# zinc, metal cobalt, and intermediate copper-silicon alloy. Samples are obtained from the extruded blanks, and back-furnace components are tested. As the test instrument, an Inductive Coupling Plasma spectrograph (ICP) is used.

Materials in each group are casted and ingoted in a 10 Kg intermediate frequency furnace, then turned into ⁇ 50 extruded ingots, and finally extruded into ⁇ 15 blanks.
the extruded blanks are cooled with water online.
the following processing is successively performed on the extruded blanks: cold drawing at a working rate of 60% ⁇ aging heat treatment for 5 h at 550°C ⁇ cold drawing at a working rate of 30% ⁇ aging heat treatment for 4 h at 450°C ⁇ cold drawing at a working rate of 20% ⁇ heat treatment on finished products for 3 h at 280°C ⁇ cleaning.
the finished products are machined into ⁇ 7 standard tensile samples. Tensile tests are performed on the samples on a 10-ton hydraulic drawing machine to test the tensile strength, yield strength, ductility and modulus of elasticity of the samples. The finished products are cut into a length of 80 cm, and then the conductivity of the finished products is measured by a bridge tester. Various data is shown in Table 9.
