MACOR Ceramics/MGC/INNOVACERA

Machinable glass ceramic is a highly electrical insulating, heat insulating, vacuum tight composite material of glass and ceramics. It is machinable with common tungsten carbide or high speed steel cutting tools by turning, milling, drilling and sawing.

 

Due to the machinability, customers can produce the ceramic parts in their own common workshop or laboratory, mainly for applications as electrical insulators, vacuum components, etc. Different sizes of standard length or customers' parts are available. 

Our machinable glass ceramic has good machining performance, and can be turning, milling, grinding, drilling, drilling and tapping and other machining by ordinary machine tools and cutting tools.The machining accuracy can reach up to 5μm, finish high up 0.5μ. It has a good vacuum, high and low temperature resistance, insulation and acid and alkali corrosion resistance ect properties. 

 

Dimensions:

 

Rod: Dia20 ~ 50 × L 20 ~ 200 mm , Dia60 ~ 80 × L 20 ~ 70 mm

Plate and bar : 300X200X53 mm MAX.

Special Properties:

Typical Applications:

Macor is a machinable glass ceramic material that posses outstanding engineering properties. Unlike other ceramics, Macor can be machined with ordinary metalworking tools. Macor is also a problem solving material combining the performance of a technical ceramic with the versatility of a high performance plastic. Macor has no porosity and when properly baked out, will not outgas. It is strong and rigid and, unlike high temperature plastics, will not creep or deform. Macor is also radiation resistant.

 

 

Features and Benefits:

Ultra High Temperature Performance (800 C continuous - 1,000 C peak). Low Thermal Conductivity.

Excellent Insulator. No porosity. Will not outgas. Professional Plastics stocks a large inventory of Macor shapes used primarliy in the semiconductor probe test industry. We also supply Macor to various industries requiring high-purity, high-strength and high temperature resistance. Worldwide shipping. E-Commerce Website.
