Abstract

The invention relates to an aging-reinforced titanium-copper alloy. The aging-reinforced titanium-copper alloy is characterized by being prepared from the compositions in percentage, by weight, 2.0-4.0% of Ti, 0.5-2.0% of Ni, 0.05-0.5% of P and the balance copper and unavoidable impurities. By controlling the matching ratio of Ni to P to Ti, the yield strength of the aging-reinforced titanium-copper alloy is up to 900-1150 MPa, the conductivity is up to 12-22% IACS, and excellent bending machinability, high-temperature softening resistance and welding properties are obtained. The aging-reinforced titanium-copper alloy is especially applicable to the fields of connectors, terminals, relays and the like.

Description

technical field

[0001] The invention relates to the field of copper alloys, in particular to an aging-strengthened titanium-copper alloy. The titanium-copper alloy has good strength, electrical conductivity, bending processability, and high temperature resistance, and has good welding and electroplating properties, and can be used in Connectors, terminals, relays and other fields. Background technique

[0002] Titanium-copper alloy has high strength, hardness and excellent stress relaxation resistance. With the development of the information age, its demand is increasing, and it is widely used in terminals and connectors of high-end electronic equipment. At present, due to the continuous development of electronic equipment towards miniaturization and weight reduction, electronic and electrical components such as connectors are also constantly evolving towards miniaturization and weight reduction. However, when the connector is thinned and the spacing is narrowed, the reduct...
