Aluminum 6065 VS 6005 Aluminum

Differences Between Aluminum 6065 And 6005–Aluminum 6065 Vs 6005

6000 series aluminum 6005 and 6065

Both aluminum alloy 6005 and aluminum alloy 6065 are less common alloys in the 6000 series. The 6 series aluminum metal has added elements such as silicon and magnesium, and has higher strength and corrosion resistance than the 1000 series pure aluminum alloy. Among them, aluminum 6065 and 6005 are rare aluminum metals in the 6xxx series, and there are similar characteristics and differences between the two.

What is 6065 aluminum alloy?

6065 aluminum alloy is a high-strength aluminum alloy, mainly composed of aluminum, magnesium and silicon.

6065 aluminum has high strength, and the service strength is usually between 300 MPa and 400 MPa, and the tensile strength is between 350MPa and 450 MPa.

6065 aluminum alloy is an aluminum alloy material with excellent performance and wide application.

6065 aluminum alloy can obtain good casting performance or processing plasticity, which is easy to make products of various shapes and specifications.

Therefore, it has strong applicability in many fields such as aerospace, shipbuilding, transportation, architectural decoration, electronic appliances, etc.

6065 aluminum alloy can increase its strength through heat treatment. Common heat treatment methods include aging treatment (6065 T6) and natural aging treatment (6065 T4).

Introduction to 6005 aluminum alloy

What is 6005 aluminum? 6005 aluminum alloy is a medium-strength and high-corrosion-resistant aluminum alloy belonging to the Al-Mg-Si series.

Aluminum alloy 6005 has good processing performance, welding performance and forming performance, and can be widely used in many fields.

6005 aluminum alloy has excellent welding performance and can be connected by a variety of welding methods, such as argon arc welding, resistance welding, laser welding, etc.

This also makes 6005 aluminum alloy easier to process and can be formed by cutting, drilling, milling, stamping and other methods.

6005 aluminum alloy has good corrosion resistance and has good stability to most common corrosive media such as air, water, acid, etc.

It can be well applied in outdoor and humid environments.

6005 aluminum alloy is closely related to 6005A aluminum alloy, but it is not exactly the same.

The main difference between the two alloys is that the minimum percentage of aluminum in 6005 is higher than that in 6005A (but the maximum percentage is basically the same).
