Marine Application Anti-Corrossion 5052 Aluminum Solid Round Bar

Introduction

5052 aluminum rod possesses high plasticity and corrosion resistance.

It can not be strengthened by heat treatment, but it has good plasticity during semi-cold work hardening, low plasticity during cold work hardening, good corrosion resistance, good weldability, poor machinability, polishing .

Good corrosion resistance, good forming process, and medium strength 5052 belongs to the Al-Mg series alloy and has a wide range of applications. Especially the construction industry cannot do without this alloy. It is a promising alloy. Good corrosion resistance, excellent performance, good cold workability, and medium strength. The main alloying element of 5052 is magnesium, which has good forming performance, corrosion resistance and medium strength. It is used to manufacture aircraft fuel tanks, oil pipes, and sheet metal parts of transportation vehicles and ships, meters, street lamp brackets and rivets, hardware products, Electric-device housing, etc. ② AL-Mn series alloy is a kind of rust-proof aluminum widely used.

This alloy has high strength, especially strength: plasticity and corrosion resistance are high, and cannot be strengthened by heat treatment. The plasticity is good when hardened by cold work. Low plasticity when hardened, good corrosion resistance, machinability, and polishing. Uses are mainly used for low-load parts that require high plasticity and work well in liquid or gaseous media, such as fuel tanks, gasoline or lubricating oil pipes, various liquid containers and other low-load parts made by deep drawing: wire is used for making rivet.
