築材料、熱交換器など多くの用途に使用されている。Copper has long been known to be an excellent conductor of electricity and heat, and has good workability, and has been used in many applications such as vessels, decorations, building materials, and heat exchangers.

記説明した状況に鑑みなされたものである。Incorporating alloying elements into steel improves the workability of copper,
Although their high electrical and thermal conductivity is reduced, recent industry demand for copper and copper alloy materials is particularly evident in key applications such as air conditioning piping, heat exchanger piping, and architectural piping. With the soaring value of copper materials, there is a trend toward thinner pipe materials, higher strength, and improved electrical and thermal conductivity and corrosion resistance, centered on reducing the amount of materials used. On the other hand, these alloys, such as phosphorus-deoxidized copper, CAD 192 alloy and CAD 194 alloy, do not fully satisfy these demands, and therefore have good processability and high electrical and thermal resistance. A high-strength steel alloy having a conductivity of 1, ie, a highly conductive copper-based metal according to the present invention was developed in view of the above-mentioned situation.

いる。Good workability also has the effect of contributing to a reduction in manufacturing costs mainly for manufacturers; It goes without saying that these are contradictory, but if both can be improved in a desirable direction, this can be achieved by adding other alloying elements, but the high conductivity steel-based alloy according to the present invention In some cases, the objective is to improve electrical and thermal conductivity.

The total weight of 0.01 to 0.6 is 0.01 to 1.
By employing an alloy containing either 0% by weight, the remainder consisting essentially of Cu, and precipitated iron phosphide, a material having the aforementioned desirable properties can be obtained. It is possible to compensate for the insufficient strength of CAD192 alloy and CAD194 alloy with a nearly satisfactory degree of workability.
本発明に係る高導電性銅基台金において、Ｆｅ。In the highly conductive copper base metal according to the present invention, Fe.

量％する。If the Fe content is less than 0.04% by weight, there is no effect even if it coexists with , and if the Fe content exceeds 0.155% by weight, for example, CAD 192 alloy and CAD
As seen in the 194 alloy, work hardening per unit working rate is severe, so it is difficult to apply to the manufacturing process of deoxidized steel, and if it is to be applied, intermediate annealing must be used, resulting in poor manufacturability. The Fe content is set at 0.904% to 0.155% by weight, since this will reduce the deterioration of the structure and cause the structure to become non-uniform.

。Sn2Sn forms a solid solution in the base material, and together with iron phosphide, it refines the crystal grains and contributes to improving strength. However, since it forms a solid solution, if it is added too much, the conductivity will decrease and the high conductivity characteristic of Cu will be reduced. Since S is lost, the content should not exceed 0.6% by weight, while S
If the n content is less than 0.011% by weight, no improvement in strength can be expected, so the Sn content is set to 0.01 to 0.6% by weight.
