Embodiment 1

[0015] The weight percentages of the components in the aluminum alloy in this example are as follows: Si: 0.40%, Mg: 0.64%, Cu: 0.02%, Fe: 0.23%, Sr: 0.03%, La: 0.14%, Nd: 0.18%, Zn : 0.03%, Ti: 0.05%, and the rest is Al.

[0016] The above components are used to prepare aluminum alloy profile products. The specific preparation method is: after mixing the components evenly, they are homogenized in the aluminum rod furnace to improve the uniformity of the overall performance, so that the material has both appropriate hardness and toughness. Then it is cooled by air, and the ingot is heated at 450-500°C, and then sent to the extruder for extrusion. The temperature of the extrusion barrel is 400°C±10°C, and the extrusion speed is 3-6m / min. After mist quenching, after cutting, cooling bed cooling, stretching and straightening, artificial aging is carried out. The holding temperature is 250°C±10°C, and the time is 180min, to obtain the finished aluminum alloy. After testing, the h...

Abstract

The invention discloses an aluminum alloy fishing barrel. The aluminum alloy fishing barrel comprises a barrel body and a lifting handle arranged at the upper part of the barrel body, wherein the barrel body is made of aluminum alloy; the aluminum alloy is prepared from the following components in percentage by weight: 0.40 to 0.44 percent of Si, 0.64 to 0.66 percent of Mg, 0.02 percent of Cu, 0.23 to 0.25 percent of Fe, 0.02 to 0.03 percent of Sr, 0.14 percent of La, 0.18 percent of Nd, 0.03 to 0.05 percent of Zn, 0.02 to 0.05 percent of Ti and the balance being Al. The aluminum alloy fishing barrel has the advantages of smooth surface, wider hardness range and good stress corrosion resistance.

Description

technical field [0001] The invention relates to the field of material engineering, in particular to an aluminum alloy salvage barrel. Background technique [0002] Aluminum alloy has the advantages of light weight and easy availability of raw materials, and has been gradually used in marine operation equipment. Although aluminum alloys used in marine operation equipment have certain corrosion resistance, in the process of measuring the corrosion resistance of aluminum alloys, the aluminum alloys are often completely submerged in seawater as a prerequisite or evaluated under salt spray conditions. In fact, the aluminum alloy of marine operation equipment is often on the seawater-air interface, and the corrosion at this two-phase interface is more serious than that completely submerged in seawater. At present, few aluminum alloys can cope with this situation. In addition, aluminum alloys for marine operation equipment are often subjected to various stress loads, so stress cor...
