Nowadays, the domestic tungsten carbide industry is mixed. Imported tungsten carbide, raw tungsten carbide, recycle tungsten carbide are rampant in the market. It is also difficult for consumers to distinguish true from false. Once you buy recycle tungsten carbide or fake imported tungsten carbide, if you find it early, you will lose the money for the material. If you find it late, you will lose the processing fee and lose the customer. Therefore, you must go to a regular merchant or physical store to purchase materials. Chengdu Woco Carbide has always insisted on using the highest quality raw materials to produce tungsten carbide products, and resolutely put an end to any form of recycle materials. Before leaving the factory, all products undergo strict testing to ensure that each product is qualified. Today, I will teach you a little bit about how to distinguish between raw tungsten carbide and recycle tungsten carbide. First: The density of recycle tungsten carbide must be lower than that of raw tungsten carbide. For example: YG15 tungsten carbide: Density: 13.90-14.20g/cm³ We can measure the external dimensions of the tungsten carbide we bought, and then calculate the volume according to the external dimensions, and then weigh the weight in KG, by the formula: density=weight/volume (Note that KG is converted to g, and the unit of volume is CM³) If the calculated density is lower than the national standard density of YG15, it can be concluded that this piece of tungsten carbide is absolutely recycle tungsten carbide. Second: The rough surface of recycle tungsten carbide blank is very rough. Third: The finish of recycle tungsten carbide cannot be reached after fine grinding, and there will be black spots, and in serious cases, there may be pores or sand holes. Fourth: Wire breakage will occur during slow-moving processing of recycle tungsten carbide. The above is enough to judge the raw tungsten carbide and the recycle tungsten carbide.
