Environmental protection of cut-resistant tungsten wire

Cutting-resistant tungsten wire is a high melting point, durable material, widely used in photovoltaic silicon wafer cutting, electric spark wire cutting (EDM), precision machining, nuclear shielding and other fields. Combining its material properties, production process and actual application analysis, its environmental protection is mainly reflected in the following aspects:

1. Reduce resource-consuming pollution

As a substitute for traditional high-carbon steel wire, the life of tungsten wire can reach 10-20 times that of similar materials (such as the life of EDM cutting wire is extended to more than 40 times), significantly reducing the frequency of replacement of metal consumables. Taking the mechanical processing industry as an example, the amount of metal waste generated by tungsten wire under the same output is only 5%-8% of high-carbon steel, and its high cutting accuracy can reduce the loss of raw materials.

2. Avoid the risk of toxic substances

Tungsten-based alloys can replace harmful materials in many fields:

Ray shielding field: tungsten-nickel-copper alloy replaces lead-containing protective materials (such as medical CT equipment shielding layer), avoiding lead pollution and increasing shielding efficiency by 70%;

Electronic industry: replace cadmium-containing electrode materials to avoid heavy metal electroplating pollution;

Military industry: as an environmentally friendly substitute for depleted uranium alloys, it solves the problem of radioactive residues.

3. Strengthening of circular economy characteristics

Recyclability: Waste tungsten wire can be converted into tungsten powder recycled raw materials through high-temperature smelting (recovery rate exceeds 95%), which saves 30% energy compared with traditional metallurgical processes.

Strategic value of resources: my country’s tungsten resource reserves are the largest in the world, but the export of primary products accounts for too high a proportion, and traditional applications are mostly concentrated in low-end industries. High value-added tungsten wire products (such as ultra-fine wires with a diameter of <0.03mm) improve resource utilization efficiency and are in line with the strategic direction of sustainable development.

4. Process compatibility advantages

The tungsten wire production process is compatible with high-carbon steel wire, and the equipment conversion cost is low, which reduces the waste of resources caused by technology iteration.
