What is the main difference between 6063 aluminum alloy and 6005 aluminum alloy?

The main differences between 6063 aluminum alloy and 6005 aluminum alloy are the alloy composition, performance characteristics, and application areas.

Alloy composition

The main alloying elements of 6063 aluminum alloy are magnesium and silicon, with magnesium content between 0.4%-0.9% and silicon content between 0.2%-0.6%. While the magnesium content of 6005 aluminum alloy is between 0.4%-0.6% and silicon content is between 0.6%-0.9%. These two alloys also differ in the content of other trace elements, leading to differences in their properties and range of use.

Performance Characteristics

1. Strength and machinability: 6063 aluminum alloy has better plasticity than 6061, but its strength and machinability are not as good as that of 6061. 6005 aluminum alloy has higher tensile and yield strengths, and better fracture toughness, which makes it suitable for applications with higher strength requirements.

2. Surface gloss: The surface gloss of 6063 and 6061 aluminum alloy is better than that of 6005, so 6063 aluminum alloy is more suitable for decorative materials.

3. Application areas: 6063 aluminum alloy is commonly used in the industrial field and construction field, because of its comprehensive performance and wide range of use 6061 aluminum alloy is commonly used in aerospace, marine devices, molds, electronic products, and other occasions that require high-strength and special processing performance. 6005 aluminum alloy is commonly used in ladders, TV antennae, and other structural components, because of its high strength and is suitable for high-strength requirements of the structure.

Application Examples

Photovoltaic module frame: Photovoltaic module frames are usually made of 6063-T5 because of its high plasticity, corrosion resistance and high tensile strength. PV mounts are often made of 6005 for their higher strength and suitability for structural components.
