Magnetic property is an important index for evaluating the performance of materials in electromagnetic environment, which directly affects their applications in motors, sensors and electromagnetic devices. The magnetic properties of C70600(B10) copper-nickel alloy are characterized below:
Low magnetic permeability
The low magnetic permeability of C70600(B10) alloy means that its energy loss in electromagnetic field is low, which makes it suitable for use in devices sensitive to magnetic field. Experimental data shows that at 20kHz frequency, its relative magnetic permeability (μr) is about 1.02, exhibiting characteristics close to those of a non-magnetic material.
Good antimagnetic properties
The alloy has excellent antimagnetic properties and is able to maintain low magnetic interference in high-precision magnetic field environments.

Tests have shown that its remanent magnetic density (Br) is only 0.1 Tesla, much lower than that of conventional magnetic materials.
Temperature Stability
The magnetic properties of C70600(B10) alloy remain stable at high temperatures. This is due to its high nickel content and uniform microstructure. Experimental results show that at a temperature of 200°C, its coercivity (Hc) is only 50 Ampere-turns/square meter, which exhibits excellent thermal stability. III.
