In such seasonal variations caused by changes in the aluminum alloy, there is need to pay attention to what it? 1, spring, autumn and winter, pay attention to indoor ventilation is superior, insisted indoor humidity, the aluminum alloy at normal room temperature. 2, do not often open for Aluminum hand with water stains or other solution to avoid lock discoloration. Aluminum or change the open door handle, do not use excessive force, resulting in reduction of aluminum door service life. Hinges, door locks and other hardware accessories often sports, Shandong aluminum ingot casting factory, attack to immediately tighten loose. 3, winter indoor temperature is not too high (around 20 degrees insisted appropriate), in the use of electric heaters or other heating equipment, to stay away from aluminum, so as not to make it heat deformation. 4, aluminum edges and corners do not often friction, so as to prevent damage to fade at the edges facing materials. 5, when cleaning aluminum look stains, after Kazakh gas may be wet, wipe with a soft cloth, you can use toothpaste or furniture special cleaning agents when heavy stains, wipe clean immediately after decontamination. Pure aluminum ingot, pure magnesium and Al-Si alloys as raw material in the middle 6063 aluminum alloy, which alloy composition (mass fraction,%): 0.43Si, specializing in the production of aluminum ingot casting factory, 0.001Cu, 0.701Mg, 0.005Zn, 0.071Ti, 0.17Fe, 0.001Mn, balance Al. 6063 will be a good solution of aluminum smelting cast into aluminum rod Φ120mm, after 560 ℃ × 6h after the equalization process, the rod heated to 460 ℃ 600t extruder into different than squeezing into a solid rod extrusion extrusion ratio was 32.7 (A), 39.05 (B), 49 (C), 59.55 (D), 68.64 (E). After solid rod extrusion was subjected to aging 200 ℃ × 2h. Microstructure and alloy extrusion ratio affect the alloy's major strengthening phase Mg2Si size, with increasing extrusion ratio, the alloy grain size decreases and the strengthening phase Mg2Si alloy reduced in size, density increases. With the increase of extrusion ratio, casting aluminum ingots, alloy strengthening phase of greater density, more uniform distribution, the tensile strength, elongation and hardness increase. Specializing in the production of aluminum ingot casting factory, aluminum ingot casting, rolls Alcoa (Views) provided by Jinan Heshun Aluminium Limited. Jinan Heshun Aluminum Co., Ltd. (www.jnhsly.com) (www.jnhsly.cn) is specialized in "aluminum, aluminum, aluminum, aluminum rod, aluminum row, aluminum, aluminum rod, aluminum elbow" of the enterprise the company of "honesty, hard service" concept, to provide you with the highest quality products and services.
