    Frequently Asked Questions

    • image/svg+xmlimage/svg+xml
      What's the difference between Macor vs Shapal?

      Shapal Hi M Soft and Macor glass ceramic are often compared because they both are machinable ceramics, however, both of these materials have significantly different mechanical and thermal properties. The following are som factors to consider when choosing between Macor and Shapal.

      Thermal Conductivity

      Shapal Hi M is a thermal conductor at 90 W/(m K), Macor is a thermal insulator with a thermal conductivity of 1.46 W/(m K)

      Thermal Cycle

      Shapal is not prone to suffering from thermal shock failures while Macor is vulnerable to thermal shock – if the parts have rapid heat up and cool down cycles then Shapal is a better option.

      Maximum Temperature

      Shapal has a much higher maximum use temperature of 1900C (in an inert atmosphere) and 1000C (in air).

      Strength

      Shapal offers better bending strength (300 vs 94 MPa) as well as better compressive strength ( 1200 vs 345 MPa) when compared with Macor.

      Cost

      Macor is a cheaper material that Shapal Hi M Soft, if it can be used instead of Shapal the user will typically see significant cost reductions.

      What's the difference between Shapal vs Aluminium Nitride?

      Pure Aluminium Nitride is often the material of choice for high thermal conductivity applications, however, because it is such a hard material it is often costly to produce in small quantities or non-standard sizes. Shapal Hi M Soft is a machinable Aluminium Nitride/Boron Nitride composite material that can be machined into incredibly tight tolerances and complicated shapes while still providing excellent thermal conductivity.

      What is the maximum size of Shapal I can purchase?

      We have recently been able to increase the maximum size availability of Shapal to 300mm x 300mm x 64mm. We carry many standard sizes of Shapal in stock and can supply fully machined components or non-standard sizes on request.

    • image/svg+xmlimage/svg+xml
      What is the maximum working temperature of Shapal Hi M Soft™?

      Shapal can be used at temperatures up to 1,900°C in an inert atmosphere and up to 1,000°C in an oxidizing atmosphere. Click Here for further information.
