  • Easy to process, can make all kinds of complex shapes
  • The density is very low, only 2.5g/cm3
  • Machinable ceramics can be used in the range of – 200 ℃ ~ + 800 ℃.
  • Various electrical properties (dielectric constant, dielectric loss, bulk resistivity, dielectric strength) are excellent
  • Machinable ceramics have excellent corrosion resistance

Machinable(Macor) Ceramic Block

Machinable ceramics block has the versatility of a high performance polymer, the machinability of a metal, and the performance of an advanced technical ceramic. It is a hybrid glass-ceramic and offers a unique combination of properties from both families of materials. machinable ceramics is an excellent electrical and thermal insulator, and offers good performance in high temperature, vacuum, and corrosive environments.

Advantages of machinable ceramic blocks

One of the main advantages of machinable ceramics is that it can be machined with conventional metalworking tools. This allows for significantly faster turnarounds and substantially lower production costs when compared with other technical ceramics, making it an excellent material for both prototyping and medium-volume production runs.
