Ⅰ.
Silicon carbide ceramic bushing product introduction: Silicon carbide ceramic bushing is a high-performance material composed of a high-purity silicon carbide (SiC) ceramic panel and a metal or polymer backing plate. Its core structure combines the hard and brittleness of ceramics with the toughness of metal through precision technology to form a "rigid and soft" composite system.
1. The main components include:
Ceramic panel: made of high-purity silicon carbide (SiC).
Backing plate: often made of steel or polymer materials.
Ⅱ.
Application fields.
Silicon carbide ceramic bushings are widely used in the following industries:
Metallurgy: high temperature furnaces, wear-resistant parts.
Chemical industry: Corrosion-resistant pump valves, reactor linings.
Mechanical: bearings, seals. Energy: Photovoltaic equipment, heat exchangers.
Transportation: Auto parts. Aerospace: High temperature components.
