HEM Sapphire Machinery

GT’s HEM sapphire is used in many mechanical applications because of its large size, strength, abrasion resistance and chemical stability. HEM sapphire has undergone extensive compressive and tensile strength testing at many different temperatures in order to understand its intrinsic failure modes and suitability for different applications. HEM sapphire has thus been optimized for various mechanical applications by leveraging its intrinsic strength and the company’s application specific sapphire performance knowledge. Sapphire’s anisotropic nature requires that crystallographic orientations be optimized for the direction of forces and temperatures to which the component will be subjected.Leverage GT’s 40 years of sapphire growth, testing and fabrication knowledge to help you understand the benefits of HEM Sapphire for your mechanical applications.

The attributes of HEM sapphire machinery:Melting point of 2040 C，hardness of 9 on the mohs scale，high conductivity at cryogenic temperatures，inert to chemicals at high temperatures，low coefficient of thermal expansion，high compressive strength，high flexural strength at elevated temperatures.
