Introduction
Aluminium / aluminum alloys are a mixture of aluminium / aluminum in combination with one of these elements – copper, manganese, silicon, magnesium, and zinc.
Aluminium alloys possess varying levels of strength and durability, due to the components present in the specific alloy and also because of heat treatments and manufacturing processes. Aluminium / aluminum 4045 alloy is a wrought alloy type with good corrosion.
The following datasheet will provide more details about aluminium / aluminum 4045 alloy.
