Product Introduction:
The Graphite Blocks represent quality Graphite Blocks manufacturing at its finest, featuring a minimum 99% carbon content with ultra-low impurity levels (≤0.5% ash content). Available in sizes from 100mm to 500mm, these blocks demonstrate outstanding thermal stability with a thermal expansion coefficient as low as 2.2×10⁻⁶/℃ (100-600℃). As specialists in Customized Graphite Blocks from China, we offer both Superior Grade (resistivity ≤7μΩ•m, compressive strength ≥25MPa) and First Grade options to suit different application requirements.Engineered for extreme environments, these blocks maintain excellent structural integrity at high temperatures while offering superior electrical conductivity. The material's unique combination of properties - including a bulk density ≥1.70g/cm³ and elastic modulus ≤14GPa - makes it invaluable for metallurgical, semiconductor, and energy applications. For industries requiring quality Graphite Blocks that balance thermal resistance with mechanical strength, our customized solutions from China's graphite technology leaders deliver unmatched performance in the most challenging operating conditions.
