[New Product] Low Beryllium Copper Round Bar | Lead-Free Material with High Conductivity and High Strength

Free samples available! Ideal for applications requiring strength, conductivity, and reliability, such as connectors and semiconductor probe pins. No heat treatment required, lead-free.

The new low beryllium copper round bar product "ESHT/EHT" is a material that achieves both high conductivity and high strength. It features no need for heat treatment (already heat-treated), is lead-free compliant, and supports high current applications, making it ideal for applications that require reliability. It is primarily available in thin rod sizes, with some free samples available. 【Example of Use Cases】 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. 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 (semiconductor testing equipment, EV charging connectors, power tools, industrial equipment). Ensures stable operation in signal transmission systems (high-speed communication connectors, semiconductor test sockets). 4. Support for Miniaturization and High Density Thin rod compatibility → For fine probe pins, precision contact components, and small terminals for medical devices. Fits well with semiconductor testing fixtures and communication equipment that are advancing towards higher density. *For more details, please contact us or download the materials.
