During the inquiry process of customers, we will quote the customer a price of one kilogram， Some customers are more confused because they don’t know the weight of the cemented carbide round bar so they are not sure about the single price. Now zzbetter tell you the calculation formula of solid carbide round bar:

Given: G=π×（Diameter/2）²×Length×Density÷10⁶=    KG

Q: What is the weight of the YG10X Φ10mm*330mm round bar?

 Let's calculate together:

G=3.14×(10.4/2)2×330×14.5÷1000000=0.407KG

Attention： We generally refer to the Φ10 blanks as Φ10.3-Φ10.4 (the finished carbide rod is Φ10 and need to be ground). We generally leave them to 331 to 333 long. So use the above data to bring in. )

Some people don't know much about the density of cemented carbide grades, so zzbetter tungsten carbide co.,ltd knows that the grades of commonly used cemented carbide round bars are listed below:

Does that understand?

have mastered the calculation method of the above round bar, the calculation method of the tungsten carbide tube is even simpler, Now zzbetter tell you the calculation formula of solid carbide round tube:

(Radius of outer circle*radius of outer circle* 3.14*length*density/10⁶=weight of outer circle)—(radius of inner circle*radius of inner circle*3.14*length*density/10⁶=weight of the inner circle)= carbide tube weight

For example

Q: What is the weight of the YG10X Φ10*Φ8*330 carbide tube?

Let's calculate together:

G=5.2*5.2*3.14*330.5*14.5/1000000—3.9*3.9*3.14*330.5*14.5/1000000=0.178kg

The above is the calculation method of the round bar that zzbetter knows with you today, I hope it will be useful! Have you learned it?
