Gradient carbide die

What is Gradient Cemented Carbide?

Gradient cemented carbide is a high performance cemented carbide with multi-layer gradient structure, through special technology during the sintering process to precisely control the decarburization and flow of cobalt, form the gradient hardness from harder to softer. Harder outer to have higher wear resistance and sharper cutter edge, and softer interior to absorb higher impact, combination of these two characteristics gives better performance applied in carbide cutters and carbide dies, and prolong the tool service time in 3 to 6 times, in some application situations, can prolong 20 times!

What is Gradient Alloy?

Generally, dispersed phase in alloy material is evenly distributed, the overall performance of the material is the same, but in some cases, people often hope that the different section of the same material can have different nature or function, for example, different hardness, and hope that the different performance sections can combined perfectly, gradient alloy was invented to satisfy this hope, gradient carbide is one of the gradient alloys.
