Explanation 
  
Kennametal established since the beginning of 1938 so far has received over 500 patents for the manufacture of carbide. To ensure the best quality product from start to finish with, Kennametal own smelting ore, grinding materials, and conduct with the powder, pressing, sintering, grinding / polishing, it will give Kennametal has 
a flexible capacity to produce various grades of materials and finished products in a more Good to meet specific customer requirements. KezizTM Kennametal sintering process is one of the patent, the use of this unique process, Kenna became the world's first large-scale production and the internal surface of virtually defect-free tungsten 
carbide / carbide materials manufacturer. Unmatched quality assurance system, testing equipment and industry experience, the level of detection can be achieved Kennametal products and military nuclear industry system standards. Kennametal's goal is to ensure customers get every time from Kennametal's products are the perfect product. 
General Brand CD-650 is Kennametal stamping die industry in a classic grade with excellent bid, in North America, Europe and the Chinese market has more than ten years. 

Of CD-650 because of its excellent performance has been widely used in precision stamping dies, CD-KR887 in the CD-650, based on the maintained CD650 excellent performance, but also in the discharge process showed excellent processing performance. 

CD-KR887 material design starting point is the ability to withstand the harsh environment of the discharge process. When an ordinary tungsten carbide materials, prolonged exposure to electrical discharge machining environment, corrosion, pitting and discoloration as well as micro-cracks will be exposed to the surface. Such deficiencies
 will result in loss of strength of the material up to 60%. In the extreme conditions of electrical discharge machining, Kennametal's CD-KR887 material after 100 hours of discharge processing did not occur even after pitting, cracks and discoloration, and in the processing, the coolant can also resist mold lubricant and acid gas corrosion. 

Higher corrosion resistance - higher than conventional carbide 100 times the corrosion resistance 
Excellent mechanical properties 
Outstanding resistance to electrolytic corrosion 
Chemical resistant 
Reduce discharge machining time 
Hot isostatic pressing process and stress release 
Features: Low impact, excellent wear resistance, high strength 
Scope: stamping die - razor blades, electronic stamping, lead frame, thin lamination stamping, spring steel stamping, grinding roller, pressure die (hard metal), not suitable for punching thick stainless steel
