Apple Steels manufactures, supplies, and exports Aluminium 5052 Bars in round, flat, square, and hex profiles to buyers across industrial, marine, and structural sectors worldwide. Aluminium 5052 is a non-heat-treatable alloy with magnesium as the primary alloying element, typically 2.2–2.8%, which delivers a combination of corrosion resistance, formability, and strength that makes it one of the most widely used aluminium alloys in demanding service environments. Its response to cold working and excellent weld characteristics make it equally practical for fabricated structures and precision-machined components.
Aluminium 5052 Bars provide excellent corrosion resistance, especially in marine atmospheres and salt water exposure, without the need for surface treatment for most structural applications.
The alloy has a high strength-to-weight ratio with tensile strength up to 228 MPa and yield strength of 193 MPa in H32 temper. It retains outstanding formability for bending and shaping without breaking. It has good weldability by typical TIG and MIG procedures, making it viable for fabricated assemblies. Its machinability is suited to general workshop and CNC operations throughout a range of profiles.
Apple Steels supplies Aluminium 5052 Bars to ASTM B221, ASTM B211, and AMS 4118 standards in diameters and dimensions from 6 mm to 300 mm across round, flat, square, and hex profiles. Standard mill finish and anodising-ready surface conditions are available. Custom cut-to-length and non-standard cross-sections are available against confirmed project requirements with standard commercial lead times.
Aluminium 5052 Bars serve across five major sectors where their combination of lightweight and corrosion resistance justifies selection over heavier or less corrosion-resistant alternatives. Marine industry applications boat fittings, deck hardware, hull framing, and fuel tanks, rely on 5052's seawater resistance that surpasses 6061 and 6063 in continuous salt-exposure service. Automotive manufacturing uses 5052 bar for fuel lines, trim components, and brackets where weight reduction and corrosion resistance both carry value. The construction sector structural and architectural components specify 5052 for facades, window frames, and equipment housings in coastal environments. Chemical processing plants use 5052 bar for equipment components handling mild acids and alkalis. Aerospace secondary structural components and instrument housings also use 5052 in non-critical strength positions where corrosion resistance matters more than maximum strength.
Apple Steels maintains ready inventory across profiles and tempers for immediate dispatch, with full ASTM certification, customisation against non-standard dimensions, and export documentation for global supply, making them the practical single-source supplier for Aluminium 5052 Bar requirements at both project and production volumes.
Melting and Casting
Steel and alloying metals are loaded into an electric arc furnace. Once in the furnace, the metal is heated to a specific temperature above its melting point, usually in excess of 2800°F.
Forming
Most cast steel is formed by hot rolling—the slab, bloom, or billet is heated and passed through large rollers, stretching out the steel into a longer, thinner form.
Heat treatment
Heat treatment strengthens rolled stainless steel by recrystallizing the deformed microstructure. Most stainless steel is heat treated by annealing.
Descaling
A rolled piece of stainless steel acquires a layer of oxidized “mill scale,” which needs to be washed away to restore a shiny surface finish.
Cutting or Machining
Stainless steel is cut to a specified shape and size. The stainless steel can be sheared with circular knives, sawed with high-speed blades, or blanked with punches.
