specific Embodiment approach 1

[0009] Specific embodiment 1: In this embodiment, Si: 0.50% to 0.70%, Fe: ≤0.50%, Cu: 0.15% to 0.25%, Mg: 0.09% to 1.10%, Cr: 0.10% to 0.25%, Mn: ≤0.15%, Zn: ≤0.20%, Ti: ≤0.10%, and the rest are made of Al.

[0010] Compared with the prior art, increasing the content of Si and Mg elements can improve the strengthening effect of the alloy, and the corrosion resistance performance is good. The role of Fe element is to refine the grains. The addition of Cu to the alloy not only significantly improves the plasticity of the alloy during hot working, but also suppresses the extrusion effect and reduces the anisotropy of the alloy due to the addition of Mn. The role of Cr and Mn elements is to increase the strength and refine the grains. The role of Ti element is to reduce the columnar grain structure of the ingot, improve the forgeability of the alloy, and refine the grain. A small amount of Zn element has little effect on the strength of the alloy.

specific Embodiment approach 2

[0011] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the mass percentage consists of Si: 0.51% to 0.69%, Fe: ≤0.49%, Cu: 0.16% to 0.24%, Mg: 0.10% to 1.09%, Cr : 0.11% to 0.24%, Mn: ≤0.14%, Zn: ≤0.19%, Ti: ≤0.09%, and the rest are made of Al. Other compositions are the same as in Embodiment 1.

specific Embodiment approach 3

[0012] Specific embodiment 3: The difference between this embodiment and specific embodiment 1 is that the mass percentage consists of Si: 0.53%-0.67%, Fe: ≤0.47%, Cu: 0.18%-0.22%, Mg: 0.12%-1.07%, Cr : 0.13% to 0.22%, Mn: ≤0.12%, Zn: ≤0.17%, Ti: ≤0.07%, and the rest are made of Al. Other compositions are the same as in Embodiment 1.

Abstract

A high-precision aluminium alloy waveguide and its preparation method are disclosed. The invention solves the problem that surface quality, surface smooth finish, tensile strength and plasticity of the existing waveguide can not satisfy the operating requirement of today's high-tech field. The high-precision aluminium alloy waveguide comprises, based on mass percentage, Si: 0.50%-0.70%, Fe: <= 0.50%, Cu: 0.15%-0.25%, Mg: 0.09%-1.10%, Cr: 0.10%-0.25%, Mn: <=0.15%, Zn: <= 0.2%, Ti: <= 0.10%, the residuel of Al. The method for preparing it includes the steps of: first: casting the alloy; second: hot extrusion forming; third: cold rolling process; fourth: cold drawing process. The waveguide produced by the method of the invention has grade II of dimensional precision, 8-12 of smooth finish and more than 167N / mm<2> of tensile strength.

Description

technical field [0001] The invention relates to a waveguide and its manufacturing method. Background technique [0002] Waveguide is mainly used in communication, satellite ground station, microwave measurement and other fields. Microwave technology is the main component of the electronics industry. Using waveguide to transmit microwave energy has the advantages of wide frequency band, low loss, easy connection, small attenuation, large transmission power and buffering effect. Therefore, it is widely used in various types of radar equipment, telemetry and remote control, and long-distance communication fields. Waveguides have become an important component material in the electronics industry. With the rapid development of the national economy and the innovation of world science and technology, broadband multi-channel communication systems, fully matched load systems, standing wave measurement devices and high-performance new radars have put forward more and more stringent ...
