The purity of raw cemented carbide materials is purer than recycled materials, especially in terms of strength, hardness, and other comprehensive properties, which are far superior to recycled materials, so it is important to learn to distinguish between raw material products and recycled material products.
Three methods to distinguish between raw cemented carbide raw materials and recycled materials:
The first method: By measuring the specific gravity, since the impurity content of the recycled material is relatively high, the specific gravity of the recycled material is smaller than that of the original material, and the specific gravity of the original material is close to the theoretical specific gravity.
The second method: Analyzing the chemical composition, the impurity content of recycled materials is relatively high.
The third method: Judging from the color of the alloy, the virgin material rods have a metallic luster, while the recycled materials are gray.
Zhuzhou Kunrui Carbide Co., Ltd. specializes in the production and supply of tungsten carbide rods. All carbide bars are made of 100% virgin material, premium quality at competitive prices.
