Abstract
A composite electrode material for the point resistance welding is prepared from the Cu-based alloy containing Cd, or Cr, or the mixture of Be, Ni, and Co, or the mixture of Cr and Zr, and the crystal whisker of titanium carbide.
Description
Technical field:
The present invention relates to a kind of aluminium alloy resistance spot welding electrode material, belong to the aluminium alloy resistance spot welding electrode material technology.
Background technology
In resistance spot welding, the requirement of counter electrode material property is: 1. favorable conductive, heat conductivility; 2. higher intensity and higher softening temperature; 3. electrode metal must have high resistance of oxidation.
Electrode materials commonly used at present has following several:
1, the copper base alloy of cadmium 1% and copper 99%;
2, chromium 0.8%, the copper base alloy of copper 99.2%;
3, beryllium 0.5%, nickel 1.0%, cobalt 1.0% and surplus are the copper base alloy of copper;
4, special copper base alloy is as copper base alloy of chromium 0.65% zirconium 0.2% bronze medal 99.15% etc.
When above-mentioned copper base alloy electrode material was used in aluminium alloy pinpoint welding, because its strength of materials is lower, wear resistance is relatively poor, electrode life was shorter.
Summary of the invention:
The object of the present invention is to provide a kind of aluminium alloy resistance spot welding electrode material, this electrode materials not only has good heat-conducting and conductivity, and intensity is higher, wear resistance is good, long service life.
The present invention is realized by following technical proposals: a kind of aluminium alloy resistance spot welding electrode material is characterized in that its component and mass percent thereof are:
Copper-based material: 85～99%; Titanium carbide crystal whisker: 1～15%
Above-mentioned copper-based material is the copper base alloy of cadmium 1% and copper 99%, or the copper base alloy of chromium 0.8% bronze medal 99.2%, or beryllium 0.5%, nickel 1.0%, cobalt 1.0% and surplus be the copper base alloy of copper, or the special copper base alloy of chromium 0.65% zirconium, 0.2% bronze medal 99.15%.
The diameter of above-mentioned titanium carbide crystal whisker is 1～10 μ m, and L/D ratio is 5～1000.
The invention has the advantages that, the hardness height of this electrode materials, wear resistance is good, long service life.
