Embodiment 1

[0015] 1) An amorphous rare earth-tin-phosphorus alloy material is made by plating an amorphous coating layer on the surface of a round copper wire with a diameter of 0.1 cm, and the thickness of the coating layer is 0.1 cm. However, the content of the plating layer is 10 parts by weight with respect to 100 parts by weight of the round copper wire. In addition, the cladding layer contains elements of cerium, tin, phosphorus, titanium, vanadium, yttrium and zirconium, and based on 100 parts by weight of tin, the content of cerium is 13 parts by weight, and the content of phosphorus is 13 parts by weight. The content is 23 parts by weight, the content of titanium element is 4 parts by weight, the content of vanadium element is 5 parts by weight, the content of yttrium element is 0.3 parts by weight, and the content of zirconium element is 1.1 parts by weight.

[0016] 2) The above-mentioned amorphous rare earth-tin-phosphorus alloy material is used as a raw material to weave a b...

Abstract

The invention discloses an amorphous rare earth-tin-phosphorus alloy material, which comprises a copper base layer and a coating layer, and the coating layer is amorphous; the coating layer is coated on the surface of the copper base layer, wherein, the coating layer comprises rare earth element, tin element, phosphorus element, titanium element, vanadium element, yttrium element and zirconium element. The amorphous rare earth-tin-phosphorus alloy material has the excellent ability of anti-electromagnetic interference.

Description

technical field [0001] The invention relates to alloy materials, in particular to an amorphous rare earth-tin-phosphorus alloy material. Background technique [0002] With the rapid development of electronic technology, the application of cables is becoming more and more extensive, and the problem of electromagnetic wave leakage or interference is becoming more and more prominent. Because the electromagnetic interference emission of electronic and electrical products or the infringement of electromagnetic interference is formed through the product shell, AC / DC power supply port, signal line, control line and ground line. Electromagnetic radiation will cause serious interference to the surrounding electronic and electrical equipment and computers, causing their working procedures to be disordered, resulting in misoperation, image barriers or sound barriers, etc., resulting in serious social problems such as computer information leakage. Some data show that within a distance ...
