Machinable Ceramic Wiki

Machinable ceramics with high bn si3n4 and or aln contents can withstand very high temperatures.

Machinable ceramic wiki.

It is a white material that looks somewhat like porcelain. It is like machining chalk. The machining process can be time consuming. Mcmaster carr sells it you can get it from numerous places.

Macor machinable glass ceramic. Macor is a good thermal insulator and is stable up to temperatures of 1000 c with very little thermal expansion or outgassing. We also supply finished components. Macor machinable glass ceramic distributor and supplier for over 10 years and therefore has built up considerable expertise in the applications of macor along with techniques to machine the material into complex shapes.

Duratec 750 is a calcium silicate based material which can be easily machined and will operate up to 1000 c. It s strong machinable and electrically insulating. Shapal hi m soft and ba 2000 have thermal expansion coefficients similar to that of silicon. We offer a range of materials and hold stock of bar rod and plate for the most popular types.

It s strong machinable and electrically insulating. Aremco offers a broad range of machinable and fully dense ceramic materials for applications in which high temperature insulation thermal shock resistance and high dielectric strength are required. The material is particularly useful where a high temperature thermally insulating component is required. They developed a machinable.

01 15 2009 07 18 pm 7. Ceramic substrates components limited has been a leading official corning inc. If your careful you can even tap it too. Choose from our selection of machinable ceramic including easy to machine glass mica ceramic ultra high temperature ceramic and more.

Aremcolox and super heat ceramics include compositions based on alumina alumino silicates boron nitride glass ceramics and magnesium oxide. Values of thermal expansion vary from negative to high depending on the machinable ceramic material. But it is sold as machinable ceramic aka macor is one name for it. Halogen free garolite g 10 rods.

There might be some basic machining guidelines for it in the mcmaster catalog. It also has good electrical insulation and arc resistance. Machinable ceramics allow ceramic components to be made without the delay or expense of conventional ceramic manufacturing processes. Use garolite g 10 in place of garolite g 10 fr4 for applications that are sensitive to halogen such as in nuclear plants.

But in small volumes it can often be more economical and less time consuming than fabricating a non machinable ceramic especially when diamond grinding to final dimensions is required. Macor is the trademark for a machinable glass ceramic developed and sold by corning inc. Hot pressing is not the only route to a machinable ceramic as corning has discovered. High thermal shock.

Duratec 750 machinable ceramic. Machinable to high tolerances.
