A kind of aluminum alloy with electromagnetic shielding function and processing method thereof

Abstract

The invention relates to the field of material processing, in particular to aluminum alloy with an electromagnetic shielding function and a processing method thereof. The aluminum alloy comprises thefollowing components in percent by mass: 2-4% of magnesium, 0.5-1% of copper, 0.01-0.1% of silicon, 0.002-0.02% of lithium, 0.002-0.02% of antimony, 0.005-0.05% of iron, 0.002-0.02% of nickel, 0.011-0.075% of boron, 0.005-0.05% of cobalt, 0.003-0.03% of niobium, 0.02-0.3% of graphene, 0.024-0.72% of a conductive polymer, and the balance of aluminum and inevitable impurities. The material comprising iron, niobium and boron has strong capability of absorbing and consuming electromagnetic waves, and can absorb the electromagnetic waves outside an object so as to achieve a shielding effect; testsshow that the electromagnetic shielding performance of the material is 50-120 dB.

Description

technical field

[0001] The invention relates to the field of material processing, in particular to an aluminum alloy with electromagnetic shielding function and a processing method thereof. Background technique

[0002] Electromagnetic waves, also known as electromagnetic radiation, are oscillating particle waves emitted in space by the same and mutually perpendicular electric and magnetic fields. Electromagnetic waves can effectively transfer energy. All objects above absolute zero will release electromagnetic waves. Electromagnetic waves can be divided into radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays and gamma rays according to different frequencies. Electromagnetic wave pollution includes man-made electromagnetic wave pollution and natural electromagnetic wave pollution. Man-made electromagnetic radiation is also electromagnetic radiation in a narrow sense. It is mainly electromagnetic radiation generated when various electronic and el...
