5A05 Aluminum Rod

5A05 aluminum rod is an Al-Mg series high-strength rust-proof aluminum alloy (national standard grade, equivalent to international 5056), with a magnesium content of about 5%, and has extreme environmental corrosion resistance (especially seawater/chemical medium corrosion resistance) and excellent mechanical properties (tensile strength ≥ 265MPa). It provides round bars, hexagonal bars and other forms, supports precision turning/forging, and is specially used in high-end fields such as ship shafting, marine equipment connectors, and military load-bearing components. Its weather resistance far exceeds that of 5005 aluminum rods, and it is a special structural material in heavy corrosion environments.

1. Super corrosion resistance

- 5% magnesium content forms a dense oxide film, which is significantly better than ordinary aluminum rods (such as 5005) in corrosion resistance to seawater, salt spray and chemical media, and is particularly suitable for extreme marine/chemical environments.

2. High mechanical strength

- Tensile strength ≥265MPa, yield strength ≥110MPa, load-bearing capacity is more than 50% higher than that of 5005 aluminum rods, meeting the needs of heavy-duty structural parts.

3. Excellent weldability

- The strength retention rate of welded joints is high (≥90%), with no crack tendency, suitable for welding processing of complex structures.

4. Lightweight and convenient processing

- The density is only 2.71g/cm³, supporting precision processing such as turning, milling, forging, etc., and the surface can be anodized to enhance hardness (HV≥300).

5. Long life and economy

- The service life in a corrosive environment is 3-5 times longer than that of ordinary aluminum rods, and the overall cost is lower.
