Product Summary of MACOR® glass ceramic

Traditional machinable ceramics usually require diamond grinding once they have been fired, which can be costly. MACOR® ceramic offers a potentially lower cost, modern solution to this problem.

Comprised of 45% borosilicate glass and 55% fluorophlogopite mica, Corning’s MACOR® ceramic is ideal for machining into high-precision components. With the pliability of a soft metal, MACOR® is easily machined using ordinary metalworking tools. MACOR® glass ceramic does not require any post-firing – optimising the manufacturing process and reducing production costs.
