Cu-5%Fe合金薄板带的研制与应用

Development and Application of Cu-5%Fe Alloy Sheet Metal Strip

利用非真空感应熔炼、半连续铸造及电磁搅拌的方式,实现了Cu-5%Fe合金锭的制备,并通过现代化的成套轧制设备,实现了Cu-5%Fe合金薄板带的制备;采用金相显微镜、维氏硬度计、万能试验机等测试了其显微组织、力学性能、导电率等。另外,对Cu-5%Fe合金薄带的电磁屏蔽性能进行测试,结果显示:在14 kHz~18 GHz频率范围内,Cu-5%Fe合金的屏蔽效能都能达到60 dB(除14 kHz外)以上,可以作为军用设备的屏蔽材料。

The Cu-5%Fe alloy ingots were prepared by non-vacuum induction smelting,semi-continuous casting and electromagnetic stirring.The Cu-5%Fe alloy sheet strips were realized by modern rolling equipment.The microstructure,mechanical properties and electric conductivity were studied by metallographic microscope,Vickers hardness and universal testing machine.In addition,the electromagnetic shielding performance of the thin band of Cu-5%Fe alloy was tested,and the results show that the shielding efficiency of Cu-5%Fe alloy can reach more than 60 dB in the frequency range of 14 kHz~18 GHz,which can be used as shielding material for military equipment.
