Beryllium Copper Plate/Sheet Types

Beryllium copper plates are highly versatile materials known for their exceptional strength, conductivity, and corrosion resistance. Beryllium copper plates, such as Alloy 25 (C17200), are widely used in electrical connectors, springs, and aerospace components due to their high strength and excellent conductivity. Alloy 190 (C17500), with its lower beryllium content and good formability, is ideal for applications in telecommunications and mold making. Alloy 290 (C17510) is a cost-effective option with good machinability, making it suitable for electronics and industrial tools.

Alloy 3 (C17300) contains lead, which improves machinability, making it perfect for precision parts like bearings and valve components. Alloy M25 (Modified C17200) offers enhanced strength and wear resistance, making it a preferred choice for aerospace, defense, and tooling applications. Alloy 165 (C17000) provides a balance of strength and conductivity, commonly used in springs and automotive components. Alloy 10 (C17530), with added chromium, is used in high-performance electrical contacts and aerospace applications.

Beryllium copper plates are essential in industries requiring durable, high-performance materials. For high-quality beryllium copper plates, trusted suppliers like Stanford Advanced Materials (SAM) offer a wide range of options to meet diverse industrial needs.
