AT&M provides provides cemented carbide products with higher machanical properties. High density, good surface quality, high strength and toughness, high shock resistance are the characteristics of our product.
Cemented carbide is kind of alloy material made of the hard compounds of refractory metals and bonding metals by powder metallurgy process. Cemented carbide has a series of excellent performance such as high hardness, good wear resistance, strength and toughness, heat resistance and corrosion resistance.
Cemented carbide has high hardness, strength, wear resistance and corrosion resistance, known as the "tooth" of the industry, used for the production of cutting tools, knife tools, drilling tools and wear-resistant parts and components, widely used in military, aerospace, machining, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields,
1.Roll: an important part in the rolling mill;
2.Oil drilling: cemented carbide shaft sleeve;
3.Mining tools: wear-resistant parts with high hardness.
CISRI-AT&M applies the cold isostatic pressing, hot isostatic pressing and low-pressure sintering technologies to produce various cemented carbide products with specific requirements and with homogeneous material quality, high density, good surface quality, good toughness, shock resistance and other characteristics.
Our company has a variety of diversified self production and processing production lines for carefully and responsibly monitoring each productive process of the products required by customers, which ensures that we are able to provide the highest quality products.
Compared with the domestically widely used rubber-mixing (or paraffin-mixing) molding and sintering processes, the process used by our company has many advantages: there is no rubber or paraffin plasticizer in raw materials and the compaction density distribution is uniform, which can reduce the risk of defects in sintered compacts such as inclusion, carburization, layering and cracks. In particular, the sintered residual pores are basically eliminated, which thus greatly reduce the sources of cracks and crack propagation channels in the products and enhance the overall performance of the products.
