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 Aluminum Nitride?

    Pure Aluminum 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 Aluminum Nitride/Boron Nitride composite material that can be machined into incredibly tight tolerances and complicated shapes while still providing excellent thermal conductivity.

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

    Alumina is a very commonly used technical ceramic due to its versatile properties, however, because it is such a hard material extensive diamond grinding is often required making it costly to produce in small quantities. Macor Machinable Glass Ceramic is often a viable alternative that can allows for significantly reduced production costs. The following are some factors to consider when choosing between Macor and Alumina.

    Thermal Cycle

    Macor is vulnerable to thermal shock – if you have rapid heat up and cool down cycles Macor may not be appropriate. Shapal may be a viable alternative.

    Maximum Temperature

    Macor has a maximum use temperature of 1000C (unstressed) and 800C (stressed); Alumina does offer higher temperature capabilities.

    Wear Resistance

    The same feature that makes Macor machinable means that it has relatively poor wear resistance when compared with Alumina.

    Cost

    For smaller quantities Macor often offers significant price reductions than Alumina components.
