Product Description

Combination components of alumina/zirconia ceramics and stainless steel, through material composite and structural optimization, fully leverage the advantages of both materials. The perfect combination of complementary properties of ceramic and metal materials has become a key solution in high-end industrial fields.

Core Advantage: Perfect Combination of Complementary Performance

Advantages	Ceramic Contribution	Stainless Steel Contribution	Overall Effect
Mechanical Properties	Ultra-high hardness (HV1200-2000), wear resistance (10+ times higher than steel)	High toughness (impact resistance), ductility, fatigue resistance.	Both wear-resistant and impact-resistant, solving the brittleness problem.
Chemical Properties	Excellent chemical inertness, resistance to strong acids and alkalis (except hydrofluoric acid), non-corrosive.	Stable in mild environments; corrosion resistant in certain alloys.	Expands the range of applicable corrosive environments.
Physical Properties	Low density (3-6 g/cm³), high insulation, high melting point (>2000℃)	Good thermal/electrical conductivity, brazing/welding capability.	Lightweight + thermal/electrical management functions.
Surface Properties	Low coefficient of friction (0.05-0.2), bio-inert, non-adhesive.	Easy to process complex structures, can be polished to a mirror finish.	Self-lubricating + precision structure integration.
Economics	Long lifespan, maintenance-free.	Low-cost processing, easy connection.	Reduced life-cycle cost.
