With a Mohs hardness of 9, aluminum oxide is used in many polishing agents for industrial and consumer uses. Our aluminum oxides vary in friability, surface area, degree of calcination and particle size distribution, because polishing performance differs depending on the substrate. Example surfaces include soft metals, hard metals, painted surfaces, plastics and silicon wafers.
With the extensive product line also comes decades of experience. Let Huber’s experts help you to select the right alumina for your specific requirements.
Our Martoxid calcined alumina product portfolio begins with the extremely hard calcined Martoxid® DN grades, a series of high performing grinding agents used primarily for the first step in smoothing glass, silicon wafers, crystal surfaces and marble: •Martoxid®DN-6 •Martoxid®DN-440•Martoxid®DN-430 •Martoxid®DN-206
For polishing of steel and non-ferrous metals and for the grinding of paints and plastics, we recommend our line of intermediate preliminary polishing products: •Martoxid®MZS •Martoxid®MZS-12 •Martoxid®MZS-3
For high gloss polishing of stainless steel and non-ferrous metals or for fine grinding of plastics and paint surfaces, our soft and very soft grades of friable calcined alumina are required. Here again, a variety of Huber | Martinswerk Martoxid grades are available and include: •Martoxid®PN-6 •Martoxid®PN-202 •Martoxid®PN-505•Martoxid®PN-6(12) •Martoxid®PS-6 •Martoxid®PS-6(12)•Martoxid®PC12-3 •Martoxid®PC12-1
When looking for a high performing and reliable hard or soft abrasive agent to handle your most challenging polishing and grinding industrial applications, look no further than the broad line-up of Martoxid® calcined aluminas from Huber | Martinswerk.
