Product Description

Innovacera specializes in the manufacture of diverse metalized ceramic coil bodies for electrical inductors, including shapes like H, U, Bone-shaped,

and others. These bodies are predominantly made from 96% alumina ceramic and feature a metallized coating comprising materials such as

tungsten (W), nickel (Ni), gold (Au), among others.

Backed by over two decades of experience in metalized ceramics production, our factory offers swift solutions for R&D projects. The metalized

bodies are partially metallized, enabling the creation of highly compact ceramic inductor coil cores. This capability significantly supports the

miniaturization of electrical systems, wire-winding techniques, electronic devices, and components used in electrical coils.

 

Metallized Alumina Ceramic Coil Bodies Features:

1.Extremely high mechanical strength 
2.Excellent bond strength of the metalization.
3.High precision tolerance
4.Good soldering behavior

Metalized Ceramic Coil Bodies Application:

>Mobile Phones
>Digital Cameras
>Notebook Computers
>Liquid Crystal Displays
>Network Transformers 
>Alelectrical Products
