Product Description

96%  Alumina Metallization Ceramic Base with Gold Plating for Coil

The description of the metalized ceramic insulator
With the properties of high purity alumina ceramics and high-frequency anti-high temperature, chemical resistance, and non-deformation at any harsh working conditions, metalized ceramic bases are widely used in electronic components manufacturing. It can be formed by ceramic injection molding, dry pressing or hot pressing.
We offer a selection of types of metallization to meet different needs of different customers, the main metallization type included as following:

1. Raw ceramic body + Molybdenum (Mo/Mn) + Nickle (Ni) plating
2. Raw ceramic body + Tungsten(W) + gold (Au) plating
3. Raw ceramic body + Molybdenum (Mo/Mn) metallization only
4. Raw ceramic body + Silver (Ag) plating only



The prime features of alumina metalized ceramics
1. High bonding/brazing strength with ideal vacuum tightness between the assembly
2. Great insulation strength and volume resistivity that fit for various high voltage high current applications     
3. With diamond-like hardness to be 85 HRV and superb compressive strength 
4. Chemical stability, anti-aging even if it works in a variety of harsh environments, free of rust forever.
5. Over 276 times wear resistance in comparison with stainless steel, it leads to a long service lifespan.

The key parameters capability of metalized ceramics

Leak rate	≤1×10^-11 Pa•m3 / s	Metal layer tensile strength	≥ 150Mpa
Volume Resistivity	≥108Ω•cm	CTE	(6.5 ~ 8.0) × 10^-6 /°C
Insulation strength	≥18kV/mm (D•C)	Dielectric constant	9~10(1MHz, 20°C)
Cosmetic quality: 1. No cracks, no bubbles; 2. Evenly distributed glaze; 3. No contamination

The typical application of metalized ceramics
Metalized ceramics are widely used in electronics, high-vacuum technology, sensors, and medical fields,
like vacuum interrupters, electron tubes, feed-throughs, medical linear accelerators/ power tubes, photomultipliers, X-ray tubes, and pressure sensors


The packaging solution and transportation

Remark:
1. Metalized ceramic will be packed in a vacuum state package with desiccant.
2. Then the vacuum package will be put into export use cartons individually
3. If needed, it will be packed by wooden case, or loaded by export use pallet.
