04Frequently asked questions
Why is 5052 called marine grade?
Its magnesium content gives excellent resistance to seawater and salt spray, so it is widely used for boats and coastal equipment.
Can 5052 be anodized?
Yes, it anodizes well for protection, though the appearance is less bright than 6063.
