    Extra-High-Temperature Mica Washers

    Image of Product. Front orientation. Washers. Extra-High-Temperature Mica Washers.
    These washers won't melt, stick, or become brittle, even when exposed to temperatures as high as 1050° F. They make excellent insulators and are often used to secure electrical connections in transformers. Mica can chip and flake due to wear, however, so these washers are not recommended for high-vibration applications.

    Extra High-Temperature Easy-Machine Glass-Mica Ceramic Rods

    Image of Product. Front orientation. Ceramic. Extra High-Temperature Easy-Machine Glass-Mica Ceramic Rods.
    Also known as Macor, this glass-mica ceramic withstands temperatures up to 1470° F. You can machine complicated shapes and precision parts from it in a fraction of the time it would take using other types of fired ceramic. Its good electrical and thermal resistance make it a common choice for heating and soldering fixtures.
