Aluminium Alloy 1145 is a high-purity aluminium alloy valued for excellent formability, good corrosion resistance and high electrical and thermal conductivity.
High aluminium purity supports applications where electrical conductivity, formability and clean surface characteristics are important.
The alloy is readily formed, rolled and bent in suitable tempers.
Provides good general atmospheric corrosion resistance.
High electrical and thermal conductivity makes it useful for conductor and heat-transfer applications.
Aluminium Alloy 1145 is selected for applications that match its specific strength, corrosion, forming, machining and service characteristics.
Used for electrical conductors, foil and selected components requiring high conductivity.
Suitable for thin-gauge foil and formed products where high purity and ductility are important.
Used for light formed components, sheet and strip applications.
Suitable for selected heat-transfer applications where high conductivity is needed.
Select the temper, thickness and product form for the required strength and forming performance.
Excellent ductility makes the alloy well suited to bending, rolling and forming.
Higher-strength aluminium alloys should be considered where structural strength is a primary requirement.
The commonly listed Werkstoff / EN cross-reference for Aluminium Alloy 1145 is 3.0257. Treat this as a grade comparison, not a guarantee of interchangeability. Verify chemistry, product form, condition and governing specification against the supplier certificate before substitution.
No. It is a non-heat-treatable alloy; strength is primarily influenced by cold working and temper.
Yes. It provides good resistance to general atmospheric corrosion.
Typical uses include foil, electrical products, formed sheet and other applications requiring high-purity aluminium.
