Aluminium alloy 5052 contains nominally 2.5% magnesium, 0.25% chromium and has good workability, medium static strength, high fatigue strength, good weldability, and very good corrosion resistance, especially in marine atmospheres. It also has the low density and excellent thermal conductivity similar to other aluminium alloys. Alloy 5052 can be hardened by cold work and is not heat treatable to higher strength. The magnesium content is low enough that it does not suffer from the stress corrosion cracking that can affect alloys with more than about 3.5% Mg.
The corrosion resistance of 5052 makes it suitable for applications that come into frequent contact with saltwater, wastewater, and chlorine. It is widely recognized as the best welding aluminium. In general, this alloy offers high strength-to-weight ratio, a smooth surface, and good formability because of its high modulus of elasticity.
5052 in a flat rolled product is available in the following tempers;
- O Tensile Strength: 170-215 MPa
- H32 Tensile Strength: 215-265 MPa
- H34 Tensile Strength: 235-285 Mpa
- H36 Tensile Strength: 255-305 Mpa
- H38 Tensile Strength: 270 MPa minimum
5052 is frequently used in welding applications. Additionally, the uses for 5052 include marine parts, aircraft, architecture, general sheet metal work, heat exchangers, fuel lines and tanks, flooring panels, street lights, appliances, and rivets and wire. Because of this alloy’s outstanding corrosion resistance versus seawater and salt spray, many large marine structures and transports employ 5052.

A four-digit numerical designation system, developed by the Aluminium Association, is used to designate wrought aluminium and aluminium alloys. The first digit defines the major alloying element in the 2xxx through 8xxx alloy series, the second digit in the designation indicates the alloy modification. When the second digit is zero, it indicates the original alloy. The numbers 1 through 9, assigned consecutively, indicate modifications of the original alloy. Explicit rules have been established for determining whether a proposed composition is merely a modification of a previously registered alloy or if it is an entirely new alloy. The last two of the four digits in the 2xxx through 8xxx series have no special significance but serve only to identify the different alloys in the series.
