FAQ
What is Macor material and what is its most outstanding feature?
Macor is a machinable glass-ceramic. Its most outstanding feature is that it can be directly and precisely machined using standard metalworking tools (turning, milling, drilling, threading) without the need for post-firing, which is not possible with most ceramics and glasses.
Is Macor Rod heat resistant? What is its maximum operating temperature?
Yes, Macor offers excellent high-temperature resistance. Its continuous operating temperature is up to 800°C, with a short-term peak temperature of 1000°C.
Is Macor Rod conductive? How is its insulation performance?
Macor is an excellent electrical insulator and is virtually non-conductive. It has high volume resistivity and dielectric strength, making it suitable for high-voltage and high-vacuum insulation applications.
How precise can Macor be machined?
Macor can be machined to very high precision, typically holding tolerances within ±0.004″ to ±0.002″ (±0.1mm to ±0.05mm), depending on part complexity and machining process. It can even be machined with complex threads and fine geometries.
What is the chemical stability of Macor Rod? Is it resistant to acids and bases?
Macor is very chemically stable. It is resistant to most acids, solvents, and weak bases. However, it is not resistant to hydrofluoric acid (HF) and hot, concentrated alkalis.
