Macor Plate/Sheet/Disc Description
- Macor plates, sheets, and discs represent the versatile, foundational form of machinable glass-ceramic, offering engineers and manufacturers unparalleled design flexibility and convenience. Fabricated from pure, homogeneous Macor material, these substrates are available in thicknesses ranging from a few millimeters to several tens of millimeters, with diameters or side lengths customizable to requirement. They serve as the ideal starting stock for creating a wide array of high-performance components.
- Their core value lies in the ability to be cut, drilled, milled, and turned directly from these flat, dense blanks into highly complex precision parts—be it intricate insulating substrates with internal channels, multi-aperture sample holders, or precise spacers and viewport frames for scientific instruments. This “from-blank-to-finished-part” approach not only minimizes material waste but also significantly accelerates the cycle from design to prototype to production.
- Inheriting the intrinsic superior properties of Macor material, these plates/sheets/discs offer high-temperature resistance up to 800°C, excellent electrical insulation and vacuum integrity, near-zero porosity, and thermal expansion compatible with metals. They are extensively used in semiconductor equipment as etch components, aerospace as radome substrates, research instrumentation as insulating sample stages, and medical devices as non-magnetic carriers. Macor plates, sheets, and discs transform top-tier material performance into accessible innovation potential.

- Superior Electrical Insulation & Vacuum Performance
- Maintains high insulation resistance and dielectric strength even at elevated temperatures and high frequencies.
- Non-porous and dense material with extremely low gas permeability and outgassing, suitable for high and ultra-high vacuum environments.
- Excellent Thermal Stability
- Continuous operating temperature up to 800°C, with short-term exposure capability to 1000°C.
- Coefficient of thermal expansion closely matches most metals (e.g., steel, aluminum), enabling reliable sealing and assembly with metal components and minimizing thermal stress.
- High Mechanical Strength & Dimensional Stability
- Exhibits high hardness, compressive strength, and good wear resistance.
- Maintains excellent dimensional stability over a wide temperature range with no creep, ideal for precision platforms and metrology bases.
