Application
The beryllium oxide (BeO) is a ceramic material with high conductivity and low dielectric constant, which makes it widely used in the field of electronic technology, such as special metallurgy, vacuum electronic technology, nuclear technology, microelectronics and photoelectron technology due to its high thermal conductivity, high insulation, low dielectric constant, low medium loss, and good process adaptability.
Advantages:
1.Superior Thermal Conductivity
2.More Consistent Heat Dissipation
3.Better Uniformity of Crystalline Structure
4.Easy and Effective Metallization
5.More Durable in Semiconductor Chamber Cleaning Environments
ALB (Xiamen) Material Company Limited, a member of ALB group, has been the leading Chinese manufacturer and supplier of copper beryllium alloy material and copper beryllium semi-finished & finished machining parts since its establishment.
Be-Al Alloy is an alloy, which beryllium cast alloy parts with high conductivity and high strength, precision casting, gravity casting, sand casting, centrifugal casting and pressure casting can be used to produce beryllium copper cast, high content of beryllium makes the alloy liquid fluidity increased and has a clean function.
