Machinable Ceramic Properties

Macor machinable glass ceramic engineered to perfection.

Machinable ceramic properties. The mechanical properties of machinable ceramics tend to be lower than those of engineering ceramics. 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. However fine grained machinable ceramics are nearly as strong as alumina.

Macor is usable in an air atmosphere to 1000 c. Macor machinable glass ceramic is a white odorless porcelain like in appearance material composed of approximately 55 fluorophlogopite mica and 45 borosilicate glass. This material called macor rapidly gained favor in nasa s space shuttle program with large pieces machined to exact sizes helping to thermally insulate the cabin from the alternating hot and cold endured in. This irritation can be avoided by good housekeeping and appropriate machining techniques.

Its unique combination of properties makes it an easily machinable versatile and high performing material even in harsh operating environments where precision is a necessity. Available in a wide range of ctes. However the dust created in machining can be an irritant. It has no known toxic effects.

Building on corning s 160 years of innovation macor machinable glass ceramic is a solid trusted foundation that can help you realize your designs quicker. Machinable ceramics with high bn si3n4 and or aln contents can withstand very high temperatures.
