2.1247 high conductivity copper-beryllium alloy plate.
In the field of materials science, copper-beryllium alloys are attracting attention for their excellent electrical conductivity and mechanical properties. This alloy plate, grade 21247 is a unique engineering material that conducts electricity far beyond pure copper and other common alloys. Its electrical conductivity can reach more than 98%, which makes it irreplaceable in applications that require high electrical conductivity.
The reason why this copper-beryllium alloy plate has such high electrical conductivity is mainly due to its unique microstructure and composition. Through precision alloying technology, this alloy successfully combines the high conductivity and ductility of copper with the high strength and low density of beryllium. This makes 21247 high conductivity copper-beryllium alloy plate has excellent mechanical properties and corrosion resistance while maintaining excellent electrical conductivity.
In the electronics industry, this alloy plate is particularly widely used. Due to its excellent conductivity and stability, it is widely used in the manufacture of key components such as advanced electronic components, integrated circuits, precision connectors, etc. In addition, due to its low coefficient of thermal expansion and high thermal conductivity, this alloy plate is also used in the manufacture of key components such as heat sinks and heat sinks to ensure the stable operation of electronic devices.
It is worth mentioning that 2.The processing performance of 1247 highly conductive copper-beryllium alloy plate is also quite good. It can be easily cold-worked, hot-worked, and plastically deformed to further meet the manufacturing needs of a wide range of complex shapes and high-precision parts.
