Medical equipment aluminum extrusions profile: mainly used in stretcher frames, 医疗设备, medical beds and other medical equipment

6061 和 6063 aluminum alloy have some differences in chemical composition, mechanical properties and application fields.

1. 化学成分
6061 铝合金: mainly contains silicon, 镁, 铜, chromium and other alloying elements. 他们之中, the content of magnesium and silicon is relatively high, which gives 6061 铝 alloy excellent physical and chemical properties.

6063 铝合金: The main components are silicon and magnesium, but the manganese content is also relatively high. This chemical composition gives 6063 aluminum alloy good processability and plasticity.
2. 机械性能

6061 铝合金: Due to its high content of magnesium and silicon, 6061 aluminum alloy has high strength and hardness. After heat treatment and pre-stretching process, its processing performance, welding characteristics, electroplating properties and corrosion resistance are all excellent. 与此同时, 6061 aluminum alloy also has good toughness and does not deform after processing.

6063 铝合金: Although its strength and hardness are lower than 6061, 6063 aluminum alloy has good ductility and workability. In terms of tensile strength and yield strength, 6063 shows better fracture toughness. 此外, 6063 aluminum alloy also has good welding performance and anodizing effect.

On May 2, 2024, the U.S. Department of Commerce announced restrictions on 铝挤压型材 imported from 13 国家: 中国, Colombia, Ecuador, 印度, 印度尼西亚, 意大利, 马来西亚, 墨西哥, 韩国, 泰国, Turkey, 阿拉伯联合酋长国, Vietnam, and Taiwan. Extrusions) made a preliminary anti-dumping ruling.

The preliminary ruling was that the dumping rate of Chinese manufacturers/exporters was 4.91% (the margin after offsetting subsidies was adjusted to 0.00%, and the specific tax rate is shown in the table below), and the tax rate for non-cooperative enterprises was 376.85% (offsetting subsidies The subsequent margin adjustment is 365.19%), the dumping rate of Colombian producers/exporters is 8.85%-34.47%, the dumping rate of Ecuadorian producers/exporters is 17.23%-51.20%, and the dumping rate of Indian producers/exporters is 3.44%-39.05%, the dumping rate for Indonesian producers/exporters is 5.65%-112.21%, the dumping rate for Italian producers/exporters is 0.00%-41.67%, and the dumping rate for Malaysian producers/exporters is 0.00 %—27.51%, the dumping rate of Mexican producers/exporters is 9.18%—82.03%, the dumping rate of Korean producers/exporters is 0.00%—43.56%, and the dumping rate of Thai producers/exporters is 2.02%— 4.04%, the dumping rate of Turkish producers/exporters is 45.41%-605.72% (the margin adjustment after offsetting subsidies is 45.41%-594.55%), the dumping rate of UAE producers/exporters is 9.13%-42.29%, Vietnam The dumping rate of manufacturers/exporters is 2.85%-41.84%, and the dumping rate of manufacturers/exporters in Taiwan, China is 0.73%-67.86%.

The U.S. Department of Commerce is expected to make a final anti-dumping ruling on this case on July 15, 2024. This case involves U.S. coordinated tariff numbers 7604.10.1000, 7604.10.3000, 7604.10.5000, 7604.21.0000, 7604.21.0010, 7604.21.0090, 7604.29.1000, 7604.29.1010, 7604.29.10 90, 7604.29.3060, 7604.29.3090 7604.29.5050 Products under 0.90.0040 和 7610.90.0080.

的应用 6061 和 6063 铝挤压型材

6061 铝合金: Because of its excellent comprehensive properties, it is widely used in various industrial fields. Specifically include but not limited to:

Aerospace and defense industry: used in aircraft structural parts, 导弹部件, 卫星, 等等.
运输: manufacturing body parts, 框架, wheels and other components in the fields of automobiles, motorcycles, bicycles, 船舶, rail transit and other fields.
