Yongsheng 6000 Series Aluminium Sheet Introduction

6000 series aluminium sheet alloys are mainly composed of aluminium (Al) as the main element and magnesium (Mg) and silicon (Si) as the main alloying elements. The mechanical properties of 6000 series aluminum sheets depend on alloy composition, tempering process, heat treatment and other factors. In general, these alloys exhibit good tensile strength, elongation, and yield strength. The thermal conductivity of 6-series aluminum alloys is generally high, ranging from 150 to 200 W/m K, and the electrical conductivity is about 30% to 40% of the International Annealed Copper Standard (IACS). The hardness of the 6-series aluminium alloys may vary depending on the tempering process and alloy composition. Generally, it is available in a range of hardness values from relatively soft to moderately hard, allowing relative flexibility in a variety of applications. This type of aluminum plate is usually very strong and can withstand huge loads and pressures.

Yongsheng can provide various 6000 series aluminium alloys, including 6005, 6061, 6063, 6082 and so on.

How Is 6000 Series Aluminum Made

Melting: The aluminum ingot is melted into aluminum water at high temperature in the furnace, and becomes molten alloy after cooling.

Casting: Casting molten aluminum alloy into the desired shape or form. The most common casting methods include permanent mold casting, die casting or continuous casting, depending on the specific application and requirements.

Heat treatment: Two common heat treatment processes are solution heat treatment and aging treatment. Solution heat treatment involves heating an alloy to a specific temperature and then rapidly cooling it (quenching) to stabilize the solid solution. Aging, also known as precipitation hardening, is the process of reheating the alloy to a lower temperature to allow the formation of strengthening precipitates within the aluminum matrix.

Cold working: After heat treatment, aluminum can be further processed through cold working techniques such as rolling, extrusion or forging. These processes involve deforming the material at room temperature to improve its mechanical properties, including strength and hardness.

Finishing operations: The final step involves finishing operations such as cutting, machining, surface treatment (such as anodizing or painting) and quality inspection to meet the specific requirements of the intended application.

Compared with 1000 series aluminium sheet, 6000 series aluminium plate has higher strength. It forms alloys with elements such as magnesium and silicon, which help enhance its mechanical properties. This makes it suitable for structural components in the aerospace, automotive and marine industries; compared to some other high-strength aluminum alloys, 6000-series aluminum sheet offers a good balance of performance and cost-effectiveness without creating excess material cost.

6000 series aluminium sheet can be easily welded using a variety of techniques such as MIG welding, TIG welding and resistance welding. Although not as corrosion resistant as the 5000 series aluminium sheets, the 6000 series still has good atmospheric corrosion resistance. Its alloying elements provide a protective oxide layer on the surface that helps prevent corrosion in most environments. However, for more severe corrosive conditions, additional protective coatings or treatments may be required. 6000 series aluminum plate can also be used for cutting, drilling, milling and turning operations. It produces small chips during machining, resulting in better chip control and reduced tool wear.

One of the outstanding advantages of 6000 series aluminium sheet is its heat treatability. It can be subjected to various heat treatments, such as solution heat treating and precipitation hardening, allowing manufacturers to tailor the strength and hardness of the material to specific application requirements.

6000 Series Aluminium Strength Description

Common alloying elements in 6000 series aluminum alloys include silicon, magnesium and manganese. The addition of these elements can improve the tensile strength and corrosion resistance of the alloy. This series generally has medium to high strength levels to meet many structural and engineering requirements. Generally, 6xxx aluminum is further enhanced by heat treatment processes, including aging treatment (T4, T5, T6) and artificial aging treatment (T7, T8). Of course, the 6000 series aluminum alloy can also be processed by cold deformation, such as rolling, extrusion and drawing, etc., and has high toughness.

FAQ:

What Is The Strongest 6000 Series Aluminum?

Among the 6000 series aluminum alloys, the strongest and most commonly used one is 6061 aluminum alloy. It offers a good combination of strength, formability and weldability, making it suitable for a wide range of applications. It has a tensile strength of approximately 45,000 psi (310 MPa) in the annealed condition and can be further strengthened by heat treatment processes such as precipitation hardening, such as 6061-T6 aluminum in the annealed condition. Other high-strength alloys in the 6000 series include 6005, 6063 and 6082, each with slightly different properties and applications.

Does 6000 Series Aluminum Lose Strength When Welded?

When welding 6000 series aluminum, its strength may be reduced, especially in the heat-affected zone (HAZ) near the weld. This is because the welding process introduces heat, which affects the material’s microstructure and mechanical properties. A common phenomenon that can occur during welding of precipitation-hardened alloys such as 6061 is the formation of a softened zone in the heat-affected zone, called a “nugget zone.” This area is usually less strong compared to the base material. However, post-weld heat treatments, such as artificial aging, can be used to restore or even improve the strength of the weld and adjacent areas.

What Is The Toughest Aluminum?

In terms of toughness, 7000 series aluminum alloys are generally considered the toughest. Known for their high strength and excellent fatigue resistance, 7000 series alloys are suitable for demanding applications in the aerospace, defense and sports industries. The aluminum alloy 7075 in the 7xxx series aluminum is known as one of the strongest aluminum alloys.
