Tungsten Carbide Grade

Leader of high-end cutting tool

CB-CERATIZIT has long been forcusing on tungsten carbide production. We are capable of deliverying high quality, stable, and sepcialised carbide grade to cope with fast-changing market demands. Tungsten carbide products from CB-CERATIZIT are widly applied in every territory, such as Aerospace, Automotive, Electronic, and Medical industry.

In order to build up a professional knowledge platform, Tianjin Tooling Academy was set up in 2011. It is aimed to integrate European & Asian technology and to coach staff to become cutting tool solution experts. Through this platform, CB-CERATIZIT is able to consolidate material resource and industrial knowledge service.

Grade Property & Recommendation

Ultrafine grain
K180 :
Ultrafine grade for HSC machining of tempered steel (HRC>60), abrasive aluminium, or CFRP.
UF25 :
Ultrafine grade for HSC machining of tempered steel (HRC≤60) and stainless steel. Even more concentrated grain distribution enhances tool life and work performance.
WF25 :
Appropriate for machining tempered steel (HRC<45) and stainless steel. It is a well-balanced high performance grade.

Submicron grain
KS09 :
Appropriate for machining stainless steels, heat-resistant alloys, & difficult-to-machine materials (Ti-based, Ni-based Alloy). Excellent performance especially under unfavorable conditions.
WF15 :
Well balanced physical properties, very good at universal machining of alloyed / non-alloyed steel.Well balanced physical properties, very good at universal machining of alloyed / non-alloyed steel.
K200 :
For stainless steel & heat-resistant alloys machining under work-condition of low cutting speed & high feed rate. Selective submicron carbide grade for optimum tool toughness.

K100L :
Certified fine carbide grade for diamond coating tool. For machining graphite, composite material, and high-silicon aluminium alloy.
KR10 :
Fine grain grade specially design for machining Non-ferrous metal, Cast Iron, and Plastic.
