Another key feature is its thermal expansion; it remains strong through temperature changes. This lightweight alloy is ideal for structural applications and can be easily anodized for a durable finish, making it a strong choice for quality-oriented manufacturers. Understanding its makeup and features reveals its actual value.

Chemical Composition of 6005 Aluminum
6005 aluminum is a strong and flexible alloy made for easy use. It contains a good mix of magnesium (0.4%–0.6%) and silicon (0.6%–0.9%). This mix gives it excellent corrosion resistance and makes it easy to shape into different forms. This alloy is perfect for structural applications like railings and frames. A little bit of manganese and titanium helps make it more durable and improves its structure. This means it works well even in medium-stress situations.
