• Yield Strength: 240 MPa (35 ksi) (solution heat-treated and aged)
• Elongation: 12-17% (in 50 mm gauge length)
• Hardness: Brinell hardness 95-110 HB
• Shear Strength: 207 MPa (30 ksi)
• Modulus of Elasticity: 68.9 GPa (10.0 × 10³ ksi)

6061 aluminum alloy is a versatile material because it can be heat-treated to achieve higher strength, making it suitable for structural components. Its elongation values also suggest that it is relatively ductile, allowing it to be formed into complex shapes without cracking.

Aluminum 6061 offers good resistance to corrosion, which is one of the main reasons it is widely used in applications exposed to outdoor environments or marine conditions. The alloy forms a protective oxide layer on the surface, which helps prevent further oxidation.

Key aspects of corrosion resistance:

• General Corrosion: Highly resistant in most environments including atmospheric conditions, water, and many chemicals
• Pitting Corrosion: Resistant in most environments but may suffer in chloride-rich environments like seawater
• Stress Corrosion Cracking (SCC): Generally resistant in most conditions
• Anodizing: Easily anodized to increase corrosion resistance with more durable surface protection
