silicon carbide shaft
Product Overview
A Silicon Carbide Shaft is a precision ceramic shaft manufactured
from high-performance reaction-bonded or sintered silicon carbide
material. It represents a revolutionary alternative to metal shafts
in the most extreme operating conditions.
This product combines exceptional wear resistance, superior
corrosion resistance, high rigidity, and low density, and is
specifically designed to solve shaft application challenges in
high-speed, highly corrosive, high-temperature, and ultra-clean
environments.
Material and Properties
Core Material: Reaction-Bonded / Sintered Silicon Carbide
Extreme Hardness & Wear Resistance SiC is one of the hardest
materials in the world, second only to diamond and CBN. This gives
it super resistance to abrasive wear, resulting in a service life
far exceeding that of tool steel, stainless steel, and other
metals.
Excellent Chemical Corrosion Resistance
Resists corrosion from most strong acids (e.g., hydrochloric,
sulfuric, nitric), strong alkalis, and oxidizers. It remains stable
even in aqua regia. Its chemical stability is much higher than that
of stainless steel.
High Stiffness & Low Density
High elastic modulus means minimal bending deformation under load,
maintaining extremely high rotational accuracy.
Density is only about 3.1 g/cm³, approximately 40% that of steel,
significantly reducing the inertia of rotating components, making
it suitable for high-speed applications.
Superior High-Temperature Performance
Maintains its strength and shape at temperatures up to 1600°C,
without oxidizing or softening, far outperforming metals.
Low Thermal Expansion & High Thermal Conductivity
Low coefficient of thermal expansion ensures good dimensional
stability with temperature changes.
Good thermal conductivity helps rapidly dissipate frictional heat,
preventing thermal cracking.
