Ceramic Aluminum Oxide Vs Macor

Diamond is vastly superior.

Ceramic aluminum oxide vs macor. Macor is the trade name of a machineable glass ceramic often used for electrical applications and at high temperatures. For the last polish use alumina or cerium oxide powders on a polishing pad. Ceramic alumina is a long lasting synthetic grain produced directly as a grain through an aqueous dispersion of fine aluminum oxide powder. Ceramic alumina long lasting great for metal finishing photo c o imerys.

Zirconium oxide or zirconia is a type of ceramic with the. A breakdown of the composition of macor is as follows. Composition glass ceramic macor glass ceramic magnesium oxide1 alumino silicate aluminum oxide 1 2 boron nitride 3 aln bn composite zirconia toughened al o y tzp mgo partially stabilized 3 5 zirconia yttria stabilized 12 zirconia max operating temperature ºf ºc. Alumina also known as aluminum oxide is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications.

Macor is one of our most frequently used ceramics and is typically the most cost effective material for general technical ceramic applications. General macor machinable glass ceramic information. Aluminum oxide or alumina is the most widely applied type of ceramics often used as electrical insulator and for wear resistant applications. Aluminum oxide silicon carbide or diamond wheels can be used.

Grinding macor mgc. Macor machinable glass ceramic has the versatility of a high performance polymer the machinability of a metal and the performance of an advanced technical ceramic. Macor is a porcelain like material that is approximately 45 borosilicate glass and 55 fluorophlogopite mica. Macor exhibits good thermal shock resistance and mechanical toughness when compared to conventional glasses with similar thermal and mechanical properties.

In vacuum systems where the temperature exceeds 600 c fluorine evolution will occur manifesting itself as boron trifluoride. Both ceramic and zirconia are high performance abrasive grains that last much longer than the aforementioned aluminum oxide due to their ability to sharpen with every use unlike aluminum oxide. Start polishing with a 400 grit silicon carbide. While it can often be more expensive it lasts longer and provides a cooler sanding experience than aluminum oxide.

Shapal has significantly better mechanical properties than macor however this may not be an issue if your application does not require the material to withstand high mechanical loads. This allows zirconia and ceramic to continuously renew themselves for maximum cutting performance until the grain is fully worn. Aluminum oxide and silicon carbide wheel grades 36 or finer with open grain. Silicon sio2 46.

Macor is usable in an air atmosphere to 1000 c. It is a hybrid glass ceramic and offers a unique combination of properties from both families of materials.
