Beryllium copper, or BeCu, is often used in metal spring clips and flat springs because of its elastic properties, formability, non-metallic nature, 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 the process to ensure the BeCu battery contact meets your needs.
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 called Brush Wellman Alloy 25. Some others include alloy 290, M25 and 165, all of which are high strength alloys. There are also alloys that are made for high conductivity. These are alloys 3, 10, and 174.
Production of Our Copper Contacts
All beryllium copper battery contacts and springs 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 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?
Beryllium copper battery contacts are manufactured to tight tolerance specifications. We heat-treat the parts 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 9000:2015 certified since 1998. The ISO 9000:2015 certification demonstrates continuous improvement in all areas relating to manufacturing. Our high-quality standards have allowed us to broaden our customer base within the military, medical, and aerospace industries.

Beryllium Copper Battery Contacts
Why is beryllium used in electrical contacts?
Beryllium copper is highly conductive making it an excellent choice for conducting electricity. It is a common alloy that retains its shape under constant stress and strain. It has elastic properties, formability, non-metallic nature, and high conductivity. A battery needs a stable, reliant, and safe conductor; which is why beryllium is added.
What alloys are used to produce beryllium battery contacts?
Atlantic Precision Spring uses many different beryllium copper alloys to produce its battery contacts. The most common is Wellman Alloy 25. High strength alloys we use are 290, M25, and 165; for high conductivity, we use alloys 3, 10, and 174.
How are beryllium copper battery contacts manufactured?
To start, Atlantic Precision Spring heat-treats the parts in an atmospheric oven, which has another job of reducing the amount of distortion in the spring clip. After the part has been re-checked for dimensional accuracy, a coating or finish is applied. The customer will choose what plate finish they desire. After the final decision, the finished product will be shipped out.
What are the coating or finishing options?
At Atlantic Precision Spring we offer a wide variety of coating and finishing options, to ensure your product is met entirely to your satisfaction and needs. We offer nickel, electroless nickel, gold, chrome, chromium, chromate, tin, zinc, zinc-nickel, silver, copper, phosphate, passivation, color coding, black oxide, teflon, powder coat, epoxy/plastic, tinning soldering, diconite, and e-coat. Each coating and finishing option has different results, to ensure your choice is fit for your needs, ask one of our experts to guide you through your decision!
