Products
Heavy duty self-lubricating material bearings
Heavy duty powder metallurgy self-lubricating materials are manufactured by multi-component alloying technology and powder composite process, with extremely high load-bearing capacity and excellent friction reduction and wear resistance.
Good friction pair matching makes heavy-duty powder metallurgy self-lubricating widely used in the rotating and sliding parts of various heavy equipment, which can greatly improve the service life of the equipment.
Carbon ceramic/C/C-SiC composite structural components
Carbon ceramic (C/C-SiC) composite material has a low density (1.7-2.5g/cm) 3）、 A series of advantages such as high friction coefficient (0.30-0.45), stable friction coefficient, good wear resistance, long service life, good thermophysical properties, good mechanical properties, low noise, and strong environmental adaptability make it a high-performance friction material.
Application scope: high-speed train brake pads, maglev train vertical sleds, aircraft brake pads, luxury car brake pads, high-speed elevator emergency brake pads, etc.
Copper based powder metallurgy brake materials
Copper based powder metallurgy brake materials have excellent mechanical properties, stable friction coefficient, high density, large specific heat capacity, good thermal conductivity, wear resistance, and easy processing, thus becoming the recommended materials for high-speed railway and other rail transit braking.
Application scope: linear track brake pads, high-speed rail brake pads, maglev train lateral sleds, engineering machinery friction pads, etc.
Wear-resistant ceramic composite material
Wear-resistant ceramic composite materials have high strength, abrasion resistance, and excellent wear resistance. They are an emerging material for strengthening the surface of vertical mill liners/rollers, with a service life of 4-6 times that of traditional materials.
Application scope: Vertical mill liners, grinding rollers, distribution cones, throwing heads, etc. in cement, thermal power, metallurgy, chemical and non-metallic mining industries.
Silicon carbide ceramic bulletproof sheet
The reason why ceramics are bulletproof is because of their high specific stiffness, high specific strength, and chemical inertness in many environments.
Advantages compared to metal materials:
Metal materials will undergo plastic deformation and absorb energy when resisting bullet impact, while ceramics will hardly undergo plastic deformation. The bullet will be passivated or even broken due to its high strength and hardness characteristics.
