High Strength Alumina Substrates(NA-96F1)
NIKKO’s high-strength Alumina substrates offer high strength, high toughness, and high thermal shock resistance. Their excellent thermal shock properties are ideal for applications such as heater substrates and power modules.
Features
NIKKO’s high-strength substrates show significant improvement in the thermal shock resistance compared to the standard Alumina substrates. The bending strength after a thermal shock test is over 2x compared to the standard Alumina substrate. Ideal for applications that require high thermal shock resistance. Various dimensions and thicknesses are available.
