Abstract

PURPOSE:To obtain a low-cost Cu alloy for a spring having satisfactory mechanical strength and stress relaxation resistance by providing a composition consisting of prescribed amounts of Zn, Ni, Mn and Sn and the balance Cu with inevitable impurities. CONSTITUTION:This Cu alloy for a spring consists of, by weight, 20-40% Zn, 2-10% Ni, 1-10% Mn, 0.01-3% Sn and the balance Cu with inevitable impurities. The tensile characteristics and stress relaxation resistance of the Cu alloy can further be improved by adding 0.01-3% one or more among Ta, Cr, Co, Zr, V, Be, Cd, As and P as secondary components. Since the Cu alloy has the above-mentioned characteristics, it is most suitable for use as a spring material for a terminal, connector, a switch, etc., for electronic and electric appliances.

(Detailed Description of the Invention) Next, the reasons for limiting the alloy components and contents constituting the alloy of the present invention will be explained.

Cu and Zn are the basic components of the alloy of the present invention, and improve workability,
It maintains good mechanical properties and electrical conductivity. Z
The reason why the n content is set to 20 to 40 wt% is that if the Zn content is less than 20 wt%, the strength will be insufficient, and if the Zn content exceeds 40 wt%, the workability will deteriorate.

The reason why the Ni-containing Tm is set at 2 to 10 w% is that if the Ni content is less than 2 wt%, the strength and corrosion resistance are insufficient, and the N
This is because if the i content exceeds 10 wt%, processability will deteriorate and the price will also increase.

The reason for adding Mn is that it is cheaper than Ni, can be used as a partial substitute for Ni in order to improve strength, and also improves hot workability.

The reason why the Mn content is set to 1 to 10 wt% is that if the Mn content is less than 1 wt3, the effect of improving strength and hot workability is not recognized, and if the Mn content exceeds 10 wt%, the workability is adversely affected. This is because it gets worse. The purpose of adding Sn is to improve strength and corrosion resistance, and the Sn content is reduced to 0.
.. The reason why the Sn content is O, 01 to 3 wt% is that
If it is less than wt%, no improvement in strength or corrosion resistance is observed, and S
This is because if the n content exceeds 3 wt%, processability deteriorates and the price also increases.
