ZERO CERA Blocks(ASME・JIS/ISO/DIN)

• Thermal expansion in the temperature range 20±1ºC less than 1/500 that of steel
(0±0.02×10-6/K(20ºC))
• Almost no secular change both in dimension and coefficient of thermal expansion
• Complementary ultra-low thermal expansion and high specific rigidity
(Young's modulus/specific gravity)
