Alumina Ceramic Rods / Aluminum Oxide Insulation Rods for Battery
1. Description:
The recent advancements in battery technology are placing new demands on thermal management systems. Precision engineered ceramic shafts and bearings are used in the water cooling pumps of next-generation hybrid vehicles for cooling critical engine electronics and lithium-ion batteries. In addition to their longevity due to their excellent chemical resistance to the glycol coolant, ceramic products are lightweight which contributes to improved fuel efficiency and low noise running. For example, boron carbide ceramics are used in brake linings of vehicles. And silicon carbide ceramics are used for high performance “ceramic" brake disks, as they are able to withstand extreme temperatures.
