Heat expansion metal vs ceramic

WebThe method for measuring the hardness of Fine Ceramics is defined in JIS R 1610 (ISO 14705: 2000). Vickers hardness is a resistance value obtained by pressing a diamond indenter onto a test specimen. Extreme hardness is the primary feature that endows Fine Ceramics with their superior wear resistance. This has led to the use of Fine Ceramics … WebThey provide high wear, heat and corrosion resistance, as well as high tensile strength, volume resistivity, dielectric strength and modulus of elasticity. These materials also offer lower thermal expansion than metals or plastics, and a longer part life at original design dimensions and tolerances.
