Low Beryllium Copper Round Bar | Lead-free next-generation material that combines high conductivity and high strength.
It has features such as no need for heat treatment, lead-free compatibility, and support for high current, making it ideal for applications that require reliability, such as connectors and semiconductor testing components!
The new product "ESHT/EHT" made from low beryllium copper round bars is a material that combines high conductivity and high strength. It features no need for heat treatment, is lead-free, and supports high current applications, making it ideal for applications where reliability is essential. We can provide it primarily in thin rod form. 【Example of Applications】 1. Compliance with Environmental Regulations and Safety Lead-free and low beryllium → Responding to the need to replace conventional materials (such as BeCu) as environmental regulations like RoHS and REACH become stricter, while also focusing on reducing health risks for workers. 2. Cost and Process Reduction No heat treatment required → Reduces processing steps, achieving shorter delivery times and cost reductions. It is also suitable for prototype and short delivery projects that avoid complex heat treatment processes. 3. Improved Electrical Properties High conductivity → Suitable for high current applications (EV charging connectors, power tools, industrial equipment) and applications requiring low contact resistance, ensuring stable operation in signal transmission systems (high-speed communication connectors, semiconductor test sockets). 4. Support for Miniaturization and High Density Thin rod compatibility → Fits applications such as fine probe pins, precision contact components, and small terminals for medical devices, aligning well with the increasing density in semiconductor testing jigs and communication equipment. *For more details, please contact us or download the materials.
