6000 series aluminum alloy is a type of aluminum alloy that contains aluminum, magnesium, and silicon. It contains standard versions like 6061 and 6063, which are widely used in aerospace, shipbuilding, vehicles, construction, electronics, and other industries.
6xxx series aluminum alloys for aviation have evolved into 6061, 6063, 6013, 6056, and other alloys that are utilized for aircraft protective panels, skins, flanges, and other components. 6063 is commonly utilized in the design of airplane structures such as fuselages and wings.
6063 aluminum alloy is known for its excellent overall performance and is widely applied in industrial and construction fields. Compared with 6061, 6063 aluminum offers better plasticity, making it the preferred grade for most extruded profiles. However, in terms of strength and processing performance, 6063 does not match the capabilities of 6061 aluminum.
The designation 6063-T6 indicates that the alloy is 6063 and has undergone T6 heat treatment. As for the properties of 6063-T6, its typical yield strength is around 210 MPa, and its hardness generally reaches 73 HB.
A key advantage of 6061 aluminum is its heat-treatable nature. Through heat treatment, its mechanical properties-especially hardness-can be greatly enhanced. The process involves heating the alloy to a specific temperature, holding it there for a set duration, and then rapidly cooling it. Among these, 6061-T6 aluminum is one of the most commonly used tempers, offering a much higher strength level.
6061 aluminum plate was one of the earliest 6XXX series alloys adopted for aviation. It provides strong corrosion resistance and excellent weldability, though its overall strength is considered moderate to low. Historically, domestic aircraft pipeline systems mainly used LF2-M and LF21-M materials, while international applications predominantly relied on 6061-T4 and 6061-T6 aluminum alloys.
In general application performance, 6061 aircraft aluminum surpasses 7075 in corrosion resistance, weldability, and machinability. However, it cannot reach the high strength levels of 7075 aluminum. Therefore, when strength is the primary concern, 7075 aluminum is the more suitable option.
At GNEE, we supply high-quality 6063, 6061, and 7075 aluminum materials and provide technical support to help you choose the best alloy for your project.
