Abstract

The present invention relates to one kind of golden hard alloy, and features that the golden hard alloy consists of titanium nitrate 50-80 wt%, tantalum carbide 6-12 wt%, niobium carbide 4-10 wt%, Ni 7-20 wt%, Mo 2-5 wt% and C 1-3 wt%. The golden hard alloy has no need of electroplating to colorize causing environmental pollution, and no discoloring.

Description

technical field [0001] The invention relates to an alloy, especially a golden yellow hard alloy. Background technique [0002] Gold with a golden color symbolizes elegance and luxury, usually for the sake of beauty, so it has become people's pursuit to use gold to make various exquisite parts, but gold is expensive and has low hardness, so it cannot be made into watch cases and requires certain machining Therefore, when people make high-end products such as watch cases, spectacle frames, and pens, they will carry out metal electroplating and coloring on the surface of ordinary alloys—gold plating, but the use of electroplating coloring is not only easy to fade, but also during processing. The waste liquid can cause environmental pollution, and there is also a copper-based alloy based on copper with imitation gold color, but the gold color of this alloy is relatively dull, and its hardness is low.
