1050 Aluminium

1050 Aluminium is a commercially pure wrought aluminium grade containing a minimum of 99.5% aluminium. It provides excellent corrosion resistance, high electrical and thermal conductivity, good weldability and very good forming characteristics. The material is commonly selected for components that require bending, deep drawing, spinning, pressing or fabrication rather than high mechanical strength.

Solitaire Steel & Engineering LLP, based in Khetwadi, Mumbai, India, supplies and exports 1050 aluminium sheets, plates, coils, circles, pipes, tubes, round bars, flat bars, wire coils and other required forms. Material can be supplied in applicable tempers, standards, dimensions and finishes according to the buyer’s drawing, application and quantity.

Applications of 1050 Aluminium

  • Electrical Equipment: Used for busbars, conductive strips, electrical panels, cable sheathing and components requiring good electrical conductivity.
  • Chemical Processing: Suitable for tanks, equipment parts, trays and fabricated components exposed to general corrosive environments.
  • Heat-Transfer Equipment: Used for fins, heat-transfer components, heat shields and equipment requiring good thermal conductivity.
  • Food-Industry Equipment: Used for containers, trays, utensils and fabricated components where the selected specification is suitable for the intended service.
  • Lighting and Reflectors: Its bright surface and reflectivity make it suitable for lamp reflectors, lighting fixtures and decorative components.
  • Architectural Fabrication: Used for flashings, cladding parts, roofing accessories, fascia, panels and decorative metalwork.
  • General Sheet-Metal Work: Suitable for bending, pressing, spinning, deep drawing and other fabrication processes.
  • Packaging and Insulation: Used for closures, containers, protective coverings, insulation jacketing and formed packaging components.

When Should a Buyer Select 1050 Aluminium?

1050 aluminium is a suitable choice when the requirement prioritises corrosion resistance, conductivity, surface finish and formability over high mechanical strength. It is particularly useful for deeply formed, bent, spun, welded or conductive components.

Buyers requiring higher structural strength, improved machining performance or heavily loaded components should discuss grades such as 2014, 6061, 6082 or 7075 with the Solitaire Steel & Engineering LLP sales team before ordering.
