Sheet metal alloy steel 1J21

wire

Precision alloys are metal materials with special physical properties (such as magnetism, electricity, expansion, resistivity, etc.). Precision alloys play an indispensable role and can be used in industry such as electronic and electrical, consumer electronics, precision instruments, communication, sealing, sensor, aviation, energy power and others. Typical products include soft magnetic alloys (1J21, 1J22, 1J27, 1J50, 1J79, 1J85), half-soft magnetic alloys (2J4, 2J85), elastic alloys (3J21, 3J33, 3J53), expansion alloys (4J29, 4J36, 4J42, 4J50), electric-resistance alloys (6J22, 6J23) etc. The product form include strip, plate, bar, wire, ring, etc. The minimum thickness of strip is 0.005mm, the maximum width is 450mm, and the tolerance can reach ±0.5μm. Features Features are as below: • Excellent physical properties; • Accurate chemical composition, low inclusion, high purity; • High dimensional accuracy, good shape and flatness, excellent surface quality; • The weight of strip can reach up to 2800kg. Typical Applications Typical applications are as below: • Electronic and electrical products: inductor core, choke core, sensor, transformer, solenoid valve and magnetic shield, spring etc.; • Consumer electronics: screen and shield for mobile consumer products, connectors for electronic devices and wireless headsets, components for 5G base station, etc.; • Automatic control: signal amplifier, sensor, switch; • Precision instrument: pressure sensitive diaphragm; • Communication: optical fiber connector, cable shield.
