CarbiMet® 2 Abrasive Papers are the new premium line of grinding papers designed for superior grinding performance on all types of specimens. These discs are designed for wet or dry grinding; however wet grinding should induce less deformation in specimens. Like abrasive papers of the past, CarbiMet 2 offers numerous features/benefits:
Rapid material removal
Uniform surface finish
Premium "C" weight paper
Water resistant
Minimal sample deformation
Exceptional life to material removal ratio
Manufactured in an ISO 14001/2004 certified facility
   
The graph below illustrates the removal rate of each grit size, over a 3 minute period of time. As you can see the majority of material removed is within the first minute, then very little removal in minutes 2 and 3. For remarkable results, Buehler recommends using CarbiMet 2 for 1—2 minutes, especially on finer grit sizes.
 
 
 
As you can see below, we wanted to show that our new Silicon Carbide paper stands out from other papers. Using customer feedback, Buehler created an abrasive paper with excellent grinding performance. We are confident that you will experience the difference. Below you will see 5 common materials we have prepared using both our new CarbiMet® 2 and our old CarbiMet®. We wanted to provide evidence to show that the “New” CarbiMet® 2 exceeds the results of our previous version.

Tips, Tricks and Techniques
If your sample has a clean metallographic cut, free from burrs, burns and excessive deformation, then the number of steps in your grinding process will decrease.
If you are grinding a soft material and you experience embeding, lay a thin layer of candle wax over the SiC paper.  
Buehler recommends using CarbiMet® 2 papers for no more then 1-2 minutes. You might think that you are getting a good surface finish, but the paper is not removing any material after 2 minutes of grinding. See removal rate comparison graph above.
If you are having problems removing PSA papers from the platen, simply put a large 'X' of Release Agent onto the platen before placing the CarbiMet 2 paper onto the platen.

In general - hard materials can utilize fewer grinding steps than softer materials. Hard materials can tolerate large jumps in grit size.

Some materials, such as very pure lead and lead alloys, still benefit from traditional methods with 4 grinding steps.
