Product introduction? 0?3
Since its establishment in 1938, Kennametal has obtained more than 500 patents related to cemented carbide manufacturing. To ensure that products are of the best quality from beginning to end, Kennametal smelts its own ores, grinds raw materials, and carries out powder mixing, pressing, sintering, grinding/polishing, etc. This allows Kennametal to have the flexibility to produce various grades of materials and finished products for better quality. best meet customer specific requirements. KezizTM sintering process is one of Kennametal's patents. Using this original process, Kennametal has become the first manufacturer in the world to mass-produce tungsten carbide/tungsten carbide materials with almost no defects on the surface and inside. With unparalleled quality assurance systems, testing equipment and industry experience, Kennametal's product testing levels can meet the standards of military and nuclear industry systems. Kennametal's goal is to ensure that the products customers receive from Kennametal are perfect products every time.
The general grade CD-650 is a classic grade used by Kennametal in the stamping mold industry. It has excellent cost performance and has been used in more than ten markets in North America, Europe and China. years of history.
CD-650 has been widely used in precision stamping dies due to its excellent comprehensive performance. CD-KR887 is based on CD-650, which maintains the excellent performance of CD650. With comprehensive performance, it can also show excellent processing performance in electrical discharge machining.
The CD-KR887 material is designed to withstand the harsh electrical discharge machining environment. When ordinary tungsten carbide carbide materials are exposed to electrical discharge machining environments for a long time, corrosion, pitting and discoloration as well as micro-cracks will occur on the exposed surface. Such defects will cause the material to lose up to 60% of its strength. Under extreme electrical discharge machining conditions, Kennametal's CD-KR887 material still did not suffer from pitting corrosion, cracks or discoloration after 100 hours of electrical discharge machining, and it was also resistant to coolant and mold lubricants during processing. and acid gas corrosion.
