Metallographic Polishing Supplies from OnPoint Abrasives

Metallographic Polishing

Polishing provides a subtle approach to removing the final layers of surface deformation caused by the sectioning process.  There are many choices to decide from in this product range.  If you have questions, please contact us for recommendations.  We're happy to help!

 

Polishing cloths and pads for metallographic sample preparationPolishing Cloths:  Available for rough, intermediate and final polishing steps.  Our cloths are among the industry leaders for performance and efficiency.










Polycrystalline Diamond Suspension

 

Diabrasive Diamond Suspensions:
Available in Polycrystalline (Premium) and Monocrystalline (Choice) in a wide range of particle sizes.









Diamond paste for metallographic polishingDiamond Paste:
Available in Polycrystalline and Monocrystalline.
18g syringe
Water and Oil Soluble
1 micron, 3 micron, 6 micron, and 9 micron









 An excellent choice for soft materials.












Colloidal Silica Polishing Suspension

Available in standard (ProPrep) and low-crystallizing (ProPrep 2) formulas.  ProPrep suspensions are great for removing the final layer of surface deformation in materials such as steels, stainless steels, nickel alloys and engineered ceramics.
