Boron Carbide F400 Grit Wire Saw Slicing Order Page

This Boron Carbide powder is manufactured specifically for wire saw slicing.  Emphasis has been placed on grain shape during the crushing process, along with a special multi-stage gradation process.  5 lb minimum order.  Discounts available for larger quantities, see chart at bottom of page.

The F400 B4C-SWS is often used for wire saw slicing applications (40/12 micron).   F360 B4C-SWS can also be used as well (32/8 micron) for wire saw slicing.  

Please note that these two products are different from standard F360 and F400 Boron Carbide powders, so make sure you are ordering the correct item.  If the product item code contains "SWS" it is designed for wire saw slicing.  If you are seeking a boron carbide powder to polish sapphires , please look for a model number that ends with the letters "SP".
