Copper (Cu) -nickel (Ni) -manganese (Mn) -tin (Sn) -silicon (Si) alloys for high-strength wire and plate and its manufacturing method

摘要

The present invention relates to a copper (Cu) -nickel (Ni) -manganese (Mn) -tin (Sn) -silicon (Si) alloy and a method for manufacturing the same for high-strength wire rods and plate materials. The alloy component of the present invention, which is composed of a process, a continuous casting process for rods and plates, a solution treatment process, and an aging treatment process, includes nickel (Ni) of 1.0 to 8.0 wt% (weight percent) and 0.5 to 5.0 wt% (weight percent). ), Manganese (Mn), 0.1 to 8.0 wt% (wt%) tin (Sn), 0.1 to 5.0 wt% (wt%) silicon (Si), and the remainder as copper (Cu) In the process, the ingot manufacturing in the form of small diameter rods or plates in the form of cold firing is adopted as the continuous casting method, and all plastic processing in the process is cold working.
