Aluminium 1150 Data Sheet

1150 Overview

Alloy 1150 is a non-heat treatable rolled product supplied as rectangular or circular sheet, or coil. 1150 is a soft alloy with very good formability, welding and anodising qualities and with excellent corrosion resistance.

1150 Mass Conversion Factor: Kilograms (kg) per mm per square metre = 2.705kg

Anodising

1150 is very well suited to anodising and is can also be chemically brightened.

Common Applications

1150 is typically used for general sheet metal work where moderate strength is acceptable. Typical applications include metal spinning, cookware, flashing, polished trims and lamp reflectors. Alloy 1050 has similar properties and applications.

*Other common alloys used in metal spinning where higher strengths are required include 6061, 5052 and 3003.

Welding

1150 has excellent weldability by all standard methods. Filler alloy 1100, 4043 and 5356 are common, dependant upon alloy joining combinations.

Machining

Machinability of 1150 is fair in softer tempers though improves as the tempers increase (increasing strength and hardness). Accuracy of machining is managed with high speeds, ample lubrication, sharp tools, positive rakes, adequate clearance and continuous cutting.
