It has good processing characteristics and features such as 0 porosity and 0 water absorption. Its gas release rate is 0 in ultra-high vacuum environments. Therefore, many ultra-high vacuum components often require this material to make the corresponding components. MACOR is a high-performance, easy to cut special ceramic that solves the problem of ceramics not being processed with milling cutters, improves processing efficiency, and is often made into various types of precision components.
Macor Ceramics Parts Feature:
A. Corrosion resistance
Because it is made entirely of inorganic materials, it does not age or deform, is very stable to various organic solvents, and has good acid and alkali corrosion resistance.
B. Excellent weather resistance and durability
The acid and alkali resistance of crystallized glass is better than that of granite and marble, even if it is exposed to wind, rain and polluted air, it will not deteriorate, fade or lose strength.
C. High strength and light weight
Ceramic glass is harder than natural stone and is not easily damaged. The thickness of the material matches the construction method, which is in line with the mainstream of modern buildings which are light and strong.
