Project Description
Zirconia Zro2 Ceramic Positioning Pin | Ceramic Welding For Electrical Insulation
High precision round zirconia ceramic rolling pin bar with good supplier is packed in carton or according to your requirement.
Product Serial Number:202
Product details:
1)Material: zirconia ceramics
2)Function:Insulating ceramics， fixed and seal
3) High hardness.
Product Description:
High heat resistance: alumina ceramic has excellentthermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.
High electrical resistivity: alumina is an electrically insulating material.
High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
