5052 - Alloyed with 2.5% magnesium. Very good corrosion resistance, good workability, weldability and strength. Tensile strength between 31,000 to 44,000 psi.

5052 Aluminum
5052 is the alloy most suited to forming operations, with good workability and higher strength than that of the 1100 or 3003 alloys that are commercially available. 5052 is not heat-treatable, but is stronger than most of the 5xxx series of alloys. It has very good corrosion resistance, and can be easily welded. 5052 is not a good choice for extensive machining operations, as it has only a fair machinability rating.

Principal Design Features
This is a non-heat treatable alloy that is weldable. It is hardened by cold work. It has good forming characteristics and good corrosion resistance, including resistance to salt water.

Applications
Commonly used in the manufacture of hydraulic tubes, kitchen cabinets, small boats, home freezers, milk crates, aircraft tube, fencing, and appliances. Commonly used in sheet metal work and in sheet metal parts.



Machinability
This alloy has relatively fair machinability. It is easier to machine in the hard temper than as annealed and the quality of finish is better if machined in the hard condition. Oil lubricants should be used for machining, except that very light cuts may be done dry.

Forming
AL 5052 is readily formed at room temperature. Successive cold working decreases the formability.

Welding
This alloy is readily welded by conventional methods. When filler rod is required it should be aluminum alloy 5356 as filler. Either tungsten or consumable electrode inert gas shielded arc welding is preferred method.

Heat Treatment
AL 5052 cannot be hardened by means of heat treatment. It does harden due to cold working.

Forging
The alloy may be forged in the temperature range of 950 F down to 500 F.

Hot Working
Hot working, as with forging, may be done in the range of 950 F to 500 F.

Cold Working
The alloy cold works readily and may be formed by drawing or spinning. However the amount of cold work imparted by spinning makes intermediate annealing necessary.



Annealing
Anneal at 650 F and air cool.

Hardening
Hardens only from cold working.

Other Physical Props
Electrical conductivity 33% of copper.

Other Mechanical Props
Shear strength for O temper is 18 ksi. For cold worked temper H 34 it is 21 ksi.
