Copper alloy material for movable contact spring of high-voltage relay contact

The invention relates to a copper alloy material for a movable contact spring of a high-voltage relay contact, which comprises the following components in parts by weight: 90-98 parts of a material A, 0.5-5 parts of a material B and 0.04-0.1 part of a material C. The processing steps are as follows: A: carrying out a casting process to obtain a CUCp12 oxygen-free alloy rod; B, carrying out an oxygen-free copper alloy bar production process; and C, obtaining a CUCp12 oxygen-free copper alloy strip (plate) material. The specification of the anti-sticking and anti-arc high-conductivity medium-strength copper alloy material CUCp12 can meet the requirements of contacts and movable contact springs required by relays of different models. Bars with different specifications and diameters can be formed through extrusion drawing or rolling, contacts with different shapes can be formed through hot and cold heading or machine forming, plates and strips with different thicknesses and different widths are formed through rol
