Q:What is cemented carbide?

 A:Cemented carbide is a hard materialused in machining tough materials such as carbonsteel or

stainless, as well as in situations where other toolswould wear away, such as high-quantity

productionruns. Most of the time, carbide will leave a better finish on thepart, and allow faster

machining.Carbide tools can also withstand higher temperatures thanstandard high speed steel tools.

 

Q:Whatis the difference between cemented and tungstencarbide? 

A:Cementedcarbides consist of hard grains of the carbides of transitionmetals (Ti, V, Cr, Zr, Mo,

Nb, Hf,Ta, and/or W) cemented or bound together by a softer metallicbinder consisting of Co,

Ni,and/or Fe (or alloys of these metals). Tungsten carbide (WC), onthe other hand, is a compound

of W andC. Since most of the commercially important cemented carbides arebased on WC as

the hardphase, the terms "cemented carbide" and "tungsten carbide" areoften used interchangeably. 

 

Q:What are the key properties ofcemented carbides I should be concerned withwhen

selectinga grade for my application? 

A: The key properties of cementedcarbides that define their performance level fordifferent

applications include abrasionresistance (directly related to the hardness of thegrade),

fracturestrength, and fracture toughness. In general, the abrasionresistance or hardness of any grade

isinversely proportional to its fracture toughness. Very often gradeselection involves finding the best

compromise between abrasionresistance and toughness. In some instances strength andcorrosion

resistance can be importantfactors in the grade selection process. 

 

Q:Which gradecharacteristics affect the properties of cementedcarbide? 

A: The properties of cementedcarbides are affected by four primary materialcharacteristics,

namely,(i) the average grain size of the carbide phase, (ii) the weight orvolume percent of the

binderalloy present, (iii) the composition of the carbide phases, and(iv) the composition of the

binderalloy. In general, hardness increases (and fracture toughnessdecreases) as the average hard

phasegrain size decreases and/or the weight or volume fraction of thebinder decreases.

Thestrength increases as the average grain size of hard phasedecreases at any given binder fraction.

Corrosion resistance increasesas Ni and/or Cr is substituted for Co in the binderalloy.

 

Q:Which properties areimportant in metal cutting applications? 

A: Depending upon the type ofmetalcutting operation (turning, milling, drilling, etc.),different

combinations of properties isneeded in order to obtain optimum results. For example, inturning

anddrilling applications the cutting tool is in continuous contactwith the workpiece. Hence,

forthese applications, abrasion resistance and strength are the mostimportant properties to consider.

However,in operations such as milling, which invariably involve interruptedcutting, and hence high

impactforces, toughness can be an important factor. Grades employed formetalcutting applications

areusually based on fine to medium hard phase grain sizes (0.5 to 1.5mm) and low to medium

Cocontents (6 to 15 wt.%).

  

Q:Are grades used forcutting nonferrous metals different from those used for ferrousmetals? 

A: Yes. Grades used for cuttingnonferrous metals are usually based on WC as the hard phaseand

Co asthe binder phase. On the other hand, grades used for cuttingferrous metals usually contain

otherhard carbides (e.g., TiC, TaC, NbC, etc.) besides WC. The presenceof the TiC, TaC, NbC, etc.

isuseful in preventing chemical interactions between the ferrousmetals and the cutting tool (which can

lead tocratering on the surface of the tool). In addition, carbides suchas TiC, TaC, NbC, etc.

can helpincrease the hot hardness and strength of cementedcarbides. 

 

Q:Which grades are usefulin metal forming applications? 

A: In contrast to metalcutting(where abrasion resistance and strength are of paramountimportance),

cementedcarbides used in metalforming applications will invariably besubject to high impact and

shockforces. Hence, grades used for metalforming applications mustpossess high toughness levels

withadequate abrasion resistance and strength. Grades employed formetalforming applications are

typically based on coarse grainsizes (3 to 8 mm) and high binder contents (15 to 30 wt.%). 

 

Q:Which grades are usefulin earth drilling or boring applications? 

A: In many respects thecharacteristics of the grades employed for earth drilling andboring

represent a compromise betweenthe characteristics that are important for metalcutting and thosethat

areimportant for metalforming applications. Grades for earth drillingand boring must possess

thehighest toughness levels for any given abrasion resistance level,while simultaneously possessing

adequatestrength levels. The best compromise is usually arrived at by usinggrades that are based on

coarsegrain sizes (3 to 8 mm) and relatively low Co levels (6 to 16 wt.%). 

 

Q: How can I choose the most suitable products for my applications?

A: 1. Correct installation sitedepends on specific size and drawings. Especially for diesprocessing,

drawingscan ensure the finished products are qualified.

     2.Processing objects and working environment is determined bycemented carbide grades.

Products'' lifetime can begreatly extend if grades are right.
