Cu Beryllium Spring Contacts
Products Description
As a core conductive component in electrical equipment such as connectors, relays, sensors, and switches, the Cu Beryllium Spring Contacts Riveted Assembly is specifically designed for scenarios involving "high-frequency insertion and removal, vibration environments, and precision conductivity." It is an engineering-grade electrical connection solution integrating "high elastic recovery, low contact resistance, integrated riveting fixation, and fatigue and corrosion resistance." Unlike ordinary copper contacts, which suffer from rapid elastic decay, easy detachment of welded components, and unstable contact of ordinary spring contacts, this product focuses on the core concept of "high-strength beryllium copper alloy + precision riveting integration." It addresses four key pain points faced by professional buyers: contact resistance fluctuating with the number of insertions and removals, elastic decay over long-term use, contact detachment under vibration, and difficulty in adapting to various equipment specifications.

Manufacturing Advantages and Technical Features
Precision Continuous Stamping and Forming
We utilize high-speed precision stamping presses, coupled with carbide dies, to stamp and bend micron-sized Beryllium Spring for Relay into complex geometric shapes in a single process. The entire process is completed under a fully automated feeding system, ensuring the dimensional accuracy and shape consistency of each component.
Vacuum/Controlled Atmosphere Heat Treatment
Aging strengthening is a crucial step in "awakening" the properties of Becu Copper Spring Contacts. Our heat treatment furnaces operate under vacuum or a protective atmosphere, precisely controlling the temperature profile to ensure uniform precipitation of the strengthening phase while preventing surface oxidation. This is the core process that guarantees stable, peak performance in every batch of products.
High-Precision Selective Electroplating
We possess advanced selective electroplating technology, allowing precious metals to be plated only in critical contact areas. This not only maximizes the value of the precious metal material and reduces costs but also ensures excellent adhesion between the plating and the substrate, preventing peeling or flaking during long-term use.
