Problems solved by technology

Since W, Ag, etc. are precious metals, the resource reserves are limited, and the use of such precious metals as raw materials makes the cost of contact materials too expensive, which is not conducive to popularization and application
In addition, the existing contact materials have poor wear resistance and are difficult to use on sliding contacts

Abstract

A copper-based electrical contact material for a low-voltage appliance comprises, by weight, 0.004%-0.1% of Zn, 0.003%-0.09% of Ba, 0.005%-0.11% of Co, 0.001%-0.2% of Mn, 0.007%-0.5% of Cr, 0.01%-0.9% of Mg, 0.03%-1.0% of Al, 0.01%-0.2% of Ti and the balance copper. Preferably, the copper-based electrical contact material for the low-voltage appliance comprises, by weight, 0.007%-0.08% of Zn, 0.009%-0.07% of Ba, 0.008%-0.07% of Co, 0.004%-0.18% of Mn, 0.010%-0.4% of Cr, 0.05%-0.5% of Mg, 0.05%-0.7% of Al, 0.07%-0.15% of Ti and the balance copper. The copper-based electrical contact material for the low-voltage appliance has good electrical conductivity and high hardness and is resistant to wear and low in cost, and resources are abundant.

Description

technical field [0001] The invention relates to an electric contact material, in particular to a copper-based electric contact material for low-voltage electrical appliances. Background technique [0002] At present, electrical contact materials can be roughly divided into the following categories: silver-based contact materials, tungsten-based contact materials, copper-based contact materials, and noble metal-based weak current contact materials. Among them, the most representative contact material is Cu-W alloy and Ag-based contact material (AgSnO 2 , AgCdO, Ag-W series, etc.) two categories. Since W, Ag, etc. are precious metals, the resource reserves are limited, and the use of such precious metals as raw materials makes the cost of contact materials too expensive, which is not conducive to popularization and application. In addition, the existing contact materials have poor wear resistance and are difficult to use on sliding contacts. [0003] Therefore, it has becom...
