Beryllium Copper Battery Contacts

BECU contacts

Beryllium copper parts are best used for electrical contacts.

Beryllium copper “BECU” is often used in metal spring clips and flat springs because of its elastic properties, formability, non-metallic, and its electrical conductivity. Beryllium copper battery contacts are one of the more popular items manufactured here at Atlantic Precision Spring. We always produce with care and precision and can customize your request.

There are many different beryllium copper alloys that Atlantic Precision Spring uses to produce its beryllium battery contacts. The most common is UNS Designation C17200 also call Brush Wellman Alloy 25. Some others include alloy 290, M25 and 165, all of which are high strength alloys. There is also alloys that are made for high conductivity. These are alloys 3, 10, and 174.

Production of Our Copper Contacts

All beryllium copper springs and battery contacts can be prototyped first for fit and function, prior to production. These samples can be chemically etched or power press blanked before any forming, coining, drawing or tapping. The short run department is able to produce prototypes or small volume production in only a few of days. For larger volume production, progressive tools or multi-slide tools are made. These tools are run efficiently and precisely to produce beryllium copper spring clips based on custom requirements.

Why Choose APS for Your Contacts?

Atlantic Precision Spring produces many parts out of beryllium copper because of its high strength alloy and its ability to handle high conductivity. It can give the same spring force as carbon steel at a fraction of the thickness! Spring clips of beryllium copper can be made from strips as thin as 0.002″ thick and wire as thin as 0.050″.

Beryllium copper springs are manufactured to tight tolerance specifications. The process then has the parts heat-treated in an atmospheric oven, which also reduces the amount of distortion in the spring clip. Once the part has been re-inspected to ensure dimensional accuracy, a coating or finish is applied. The customer should order what plate finish he/she desires, which is determined by its application and function. Once finished, it can then be shipped out.

Atlantic Precision Spring has been ISO 9000:2008 certified since 1998. The certification demonstrates continuous improvement in all areas relating to manufacturing. It’s allowed us to broaden our customer base within the military, medical, and aerospace industries. Want to know more?
