Macor Ceramic Block

As a special glass ceramic material, macor has always attracted much attention and is widely used in many applications that require precision machining, such as aviation and semiconductors. This depends on its machinability. Traditional ceramic materials require special tools to process, while the advantage of macor is that it can be machined using standard tools. It is undoubtedly superior to other materials in terms of processing flexibility.
