So you need to mix steel with something to make it lighter and aluminium is the obvious candidate because it s so lightweight and cheap.
Lightweight steel alloys sheet metal.
Aircraft bodies and aerospace components are typically composed by lightweight materials such as aluminum titanium and magnesium alloys.
Aluminum is relatively easy to fabricate by forming machining or welding.
Its high strength hardness and workability makes stainless steel a useful metal type for a wide variety of uses.
Used in corrosion resistant applications.
Austenitic ferritic and martensitic.
This metal is a good electrical and thermal conductor.
Alloy steel stronger and harder than carbon steel alloy steel is preferred for high stress applications such as axles torsion bars and drive shafts.
O neal steel offers three different grades of stainless steel.
Perforated metal sheet materials.
Light weight metals include aluminum magnesium titanium and beryllium alloys.
Light weight for use in many aerospace applications.
This lightweight material is corrosion resistant easy to machine and a good conductor of heat and electricity.
High strength and low cost.
Aluminum and aluminum alloys are lightweight non ferrous metals with good corrosion resistance ductility and strength.
The problem here is that when you try to mix aluminium and steel an alloy of iron aluminium and carbon sometimes the aluminium and iron atoms would fuse together in weird ways forming dense crystalline structures referred to as b2.
Copper brass and bronze commonly called red metals each of these alloys has a high copper content that provides good weather resistance.
In this study incremental sheet forming process isf firstly described in 1994 was considered as an alternative to hot stamping of lightweight alloys.
