Machinable Ceramic Wiki
High thermal shock.
Machinable ceramic wiki. Machinable to high tolerances. 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. Machinable ceramics allow ceramic components to be made without the delay or expense of conventional ceramic manufacturing processes. Values of thermal expansion vary from negative to high depending on the machinable ceramic material.
Macor is a good thermal insulator and is stable up to temperatures of 1000 c with very little thermal expansion or outgassing. 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. Macor machinable glass ceramic. It also has good electrical insulation and arc resistance.
Available in a wide range of ctes. Use garolite g 10 in place of garolite g 10 fr4 for applications that are sensitive to halogen such as in nuclear plants. Macor is the trademark for a machinable glass ceramic developed and sold by corning inc. It s strong machinable and electrically insulating.
Choose from our selection of machinable ceramic including easy to machine glass mica ceramic ultra high temperature ceramic and more. The material is particularly useful where a high temperature thermally insulating component is required. But it is sold as machinable ceramic aka macor is one name for it. In stock and ready to ship.
We offer a range of materials and hold stock of bar rod and plate for the most popular types. Mcmaster carr sells it you can get it from numerous places. We also supply finished components. Hot pressing is not the only route to a machinable ceramic as corning has discovered.
It is like machining chalk. Machinable ceramics with high bn si3n4 and or aln contents can withstand very high temperatures. The machining process can be time consuming. Aremcolox and super heat ceramics include compositions based on alumina alumino silicates boron nitride glass ceramics and magnesium oxide.
There might be some basic machining guidelines for it in the mcmaster catalog. 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. If your careful you can even tap it too. 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. 01 15 2009 07 18 pm 7. Ceramic substrates components limited has been a leading official corning inc. Duratec 750 machinable ceramic.
Macor machinable glass ceramic. Halogen free garolite g 10 rods.
