Chemical Etching with Beryllium Copper

Beryllium copper is the metal of choice when it’s vital to maximize electrical properties, memory, and strength with non-magnetic and low-sparking characteristics. We leverage these qualities when manufacturing microstrip contacts, contacts, and springs.

E-Fab’s engineers and manufacturers have years of experience with the material and understand how to process Beryllium copper safely. 

We supply parts made from Beryllium copper to companies working in the  telecommunications, electronics, semiconductor, and microwave industries.

We welcome your questions about how to use Beryllium copper for your parts.

Types of Beryllium Copper We Use

We utilize Beryllium copper to manufacture a range of parts where strength and conductivity are required.

Why Choose Beryllium Copper

Electrical Conductivity
Oxidation Resistance
Corrosion Resistance
Beryllium copper — also known as Spring Copper — supplies many benefits and is one of the best metals to use when electrical conductivity is job number one. Plus, as one of the strongest copper alloys, Beryllium copper can be age hardened, formed with or against the grain, and features high ductility.
