Comparison between MACOR ® and ULE: High Performance Materials for Advanced Applications

Due to its unique properties, MACOR ® stands out in the selection of high-performance materials for precision engineering and industrial applications when it comes to machinable microcrystalline glass (ULE) and ultra-low expansion glass (ULE). Engineers and designers can make better decisions by understanding the differences between these two materials. This article compares MACOR with ULE. The focus of comparison is on characteristics, advantages, and optimal applications.

Overview of Machinable Microcrystalline Glass (Macor)

MACOR, developed by Corning Inc., is a machinable ceramic glass that combines the advantages of ceramics with the convenience of metal processing. Its main features include:

It is easy to process: standard metal processing tools can be used to process MACOR ®， Make it an excellent choice for rapid prototyping and cost reduction.

Thermal stability: It can withstand temperatures up to 800 degrees Celsius in an oxidizing environment and 1000 degrees Celsius in an inert atmosphere.

Electrical insulation: MACOR ® This is a high-quality electrical insulator with a resistivity of 10.14 ohm cm at 25 degrees Celsius and very low dielectric loss within a certain temperature range.

Dimensional stability: This material will not deform or creep, ensuring precise and consistent performance for various applications.

Zero porosity is MACOR ®® A characteristic suitable for vacuum environments and applications that require high purity and cleanliness.

Ultra low expansion glass: Overview

ULE glass is also a product of Corning. It is known for its low coefficient of thermal expansion. This makes it very stable over a wide temperature range. ULE glass has the following main characteristics:

The thermal expansion coefficient of ULE glass is very close to zero (0+-30 x 109/degree Celsius), and it has excellent dimensional stability when subjected to thermal stress.

ULE glass has high optical quality due to its purity and stability. It is used for telescopes, laser systems, and other high-precision optical applications.

Thermal stability: ULE glass can be used at extreme temperatures without dimensional changes.

ULE glass also has radiation resistance, making it suitable for nuclear and space applications.
