Alumina Ceramic Rods for Wire-wound Resistors Alias: Ceramic wire-wound rods
Description：
Customized Alumina (Al2O3) Ceramic Rods for Wire-wound Resistors, also known as ceramic wire-wound rod. This type of alumina ceramic rod is widely used in the manufacturing of electronic components and resistors due to its excellent electrical insulation, high-temperature stability, and mechanical strength. These ceramic rods have a uniform fine-toothed surface design that holds the resistance wire in place, allowing it to wrap evenly around the ceramic rod.
Features:
Alumina Ceramic Rods for Wire-wound Resistors (Alias: Ceramic wire-wound rods) are high-performance electronic components designed for resistive components and electronics manufacturing.
— High electrical insulation
These alumina ceramic rods offer excellent electrical insulation properties with a breakdown strength of more than 10 KV/mm, ensuring safe use in high-voltage environments.
— Excellent thermal stability and mechanical strength
With high thermal conductivity (27.5 W/(m.K)) and low coefficient of thermal expansion (7.6 x 10-6/℃), it maintains dimensional stability under high-temperature operating conditions while providing high compressive strength (2000 MPa) and flexural strength (330 MPa).
— Abrasion resistance and durability
The Vickers hardness reaches 15.7 GPA (1600 Kg/mm²), making these rods resistant to wear and deformation over time.
— Fine-toothed surface design
This design helps secure the resistive wire so that it can be wound evenly around the rod, providing uniform resistance values and improved current distribution.
