6061 and 6063 Aluminum Extrusions profile are two common aluminum alloy materials.

There are many types of aluminum profiles, which can be divided into many types according to their uses, including but not limited to:

Industrial aluminum extrusions profile: Mainly used in industrial production and manufacturing, such as automated machinery and equipment, enclosure frames, etc., as well as aluminum profiles customized by companies according to their own mechanical equipment requirements, such as assembly line conveyor belts, elevators, dispensing machines, Testing equipment, shelves, etc.

Aluminum Extrusions profile for construction: mainly include aluminum profiles for doors and windows and aluminum profiles for curtain walls, which are used for doors, windows, curtain walls and other structures in the construction field.

Radiator aluminum extrusions profile: mainly used for heat dissipation of various types of power electronic equipment, LED lighting fixtures and computer digital products.

Auto parts aluminum extrusions profile: mainly used for auto parts, connectors, etc.
Solar photovoltaic profiles: including solar aluminum profile frames, solar photovoltaic brackets, solar photovoltaic tile fasteners, etc.

Rail vehicle structural aluminum extrusions profile: used in rail vehicle body manufacturing, and have been increasingly used in the field of rail transit in recent years.

Framing aluminum extrusions profile: Made into aluminum alloy picture frames, used for framing various exhibitions and decorative paintings.

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

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

1. Chemical composition
6061 aluminum alloy: mainly contains silicon, magnesium, copper, chromium and other alloying elements. Among them, the content of magnesium and silicon is relatively high, which gives 6061 aluminum alloy excellent physical and chemical properties.

6063 aluminum alloy: 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. Mechanical properties

6061 Aluminum Alloy: 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. At the same time, 6061 aluminum alloy also has good toughness and does not deform after processing.

6063 aluminum alloy: 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. In addition, 6063 aluminum alloy also has good welding performance and anodizing effect.

On May 2, 2024, the U.S. Department of Commerce announced restrictions on aluminum extrusion profiles imported from 13 countries: China, Colombia, Ecuador, India, Indonesia, Italy, Malaysia, Mexico, South Korea, Thailand, Turkey, the United Arab Emirates, 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 and 7610.90.0080.

The application of 6061 and 6063 aluminum extrusion profiles

6061 aluminum alloy: 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, missile components, satellites, etc.
Transportation: manufacturing body parts, frames, wheels and other components in the fields of automobiles, motorcycles, bicycles, ships, rail transit and other fields.

Construction industry: manufacturing doors, windows, curtain walls, indoor and outdoor decorative materials, etc.

Electronic products: manufacturing mobile phone cases, computer frames, radiators, etc.

Mechanical equipment: manufacturing mechanical structural parts, molds, production line structures, etc.

Sports equipment: such as hiking poles, fishing rods, golf clubs, etc.

Solar industry: Manufacturing of solar photovoltaic frames and brackets.

6063 aluminum alloy: mainly used in the construction field, especially the frames of building aluminum doors, windows, and curtain walls.

In addition, 6063 aluminum profiles are also widely used in irrigation pipes, industrial accessories in the transportation field, etc.

In order to ensure that doors, windows and curtain walls have high wind pressure resistance, assembly performance, corrosion resistance and decorative performance, the comprehensive performance requirements for 6063 aluminum alloy profiles are much higher than industrial profile standards.
