Embodiment 1

[0011] Add 40kg of aluminum and 53kg of zinc into a resistance furnace, heat to 750°C, and after melting, add 0.015kg of lanthanum, 0.015kg of praseodymium, 4kg of tungsten and 3kg of tin, keep warm for 10 minutes, and cast to obtain a vibration-damping alloy. When the frequency is 2500hz, the damping coefficient of the damping alloy is 0.114.

Embodiment 2

[0013] Add 20kg of aluminum and 73.5kg of zinc into a resistance furnace, heat to 780°C, and after melting, add 0.02kg of neodymium, 5kg of tungsten, and 1.5kg of tin, keep warm for 10 minutes, and cast to obtain a vibration-damping alloy. When the frequency is 2500hz, the damping coefficient of the damping alloy is 0.128.

Abstract

The invention discloses a damping alloy manufacturing method. An alloy comprises components in percentage by weight as follows: 10%-40% of aluminum, 0.005%-0.03% of rare earth, 3%-5% of tungsten, 1%-3% of tin and the balance of zinc, wherein rare earth, tungsten and tin are added after zinc and aluminum are heated and fused, and the alloy is obtained through casting. Compared with the conventional zinc-aluminum based damping alloy, the damping alloy obtained with the method doesn't contain silicon, is easy to process and cut, is not prone to crushing and has good damping vibration attenuation performance.

Description

technical field [0001] The invention relates to a method for manufacturing a vibration-damping alloy. Background technique [0002] Compared with traditional cast iron vibration damping materials, zinc-aluminum alloys are widely used in vibration and noise reduction of electronic and electrical products because of their light specific gravity, high strength, and non-magnetic substances. In order to exert the vibration damping effect, the existing zinc-aluminum-based vibration damping alloy usually needs to add a certain amount of silicon, but the addition of silicon makes the alloy's machinability worse, and there is a problem of high brittleness. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the existing defects and provide a method for manufacturing a silicon-free zinc-aluminum base vibration-damping alloy. [0004] In order to solve the problems of the technologies described above, the present invention provides t...
