Battery Springs & Contacts
As a custom manufacturer of battery contacts and battery contact springs, Newcomb Spring can produce components in a virtually unlimited variety of shapes, configurations and designs. Our design assistance team can work with you to assess the manufacturing and performance considerations, as well as advise on the most cost effective process to ensure efficiency.
Spring design overview
A battery contact spring typically must perform two roles - to help provide pressure to hold batteries in place as well as to conduct electrical current from the batteries to the desired circuit. The force exerted by the spring on the battery or batteries often affects the electrical conductivity, especially where surface oxidation on the battery contacts may be present. Corrosion and oxidation, as well as the battery spring's suitability for specific soldering processes, should be considered during design.
Newcomb Spring will work with you to create an effective battery contact design for your application. With state-of-the-art equipment, a highly skilled team of spring-makers and our vast specialty material capabilities, our design assistance services can help save you time and cost on your battery springs and battery contacts.

Spring Capabilities
Newcomb Spring produces spring, wire form and metal stamped parts out of virtually any material. Often our metal parts are manufactured using stainless spring steel, though we offer a full line of material options, and can custom manufacture your part using virtually any material you require. We use continuous coil as well as strip materials, and our common material shapes include spring steel, high carbon steel, low carbon steel, nickel plated carbon steel, stainless alloys, non-ferrous metals, Elgiloy®, Hastelloy®, and more.
Battery contact material conductivity
Generally, materials with higher mechanical properties have lower electrical conductivity. Often they are used for battery contact manufacturing where cost is a major consideration and where the needed conductivity can be achieved with a pre-plated carbon steel, such as music wire, nickel coated or with a subsequent plating process. When high conductivity is required, as in military weapon applications and computers, the designer will want to consider battery contact materials with higher copper content, such as beryllium copper, phosphor bronze or spring brass. In certain applications, battery contacts and battery springs are sometimes plated in tin, silver or gold plated-remove as a subsequent operation, which increases conductivity even more.
