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.
O neal steel offers three different grades of stainless steel.
Used in corrosion resistant applications.
Austenitic ferritic and martensitic.
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.
This lightweight material is corrosion resistant easy to machine and a good conductor of heat and electricity.
Perforated metal sheet materials.
In this study incremental sheet forming process isf firstly described in 1994 was considered as an alternative to hot stamping of lightweight alloys.
Light weight for use in many aerospace applications.
Aluminum is relatively easy to fabricate by forming machining or welding.
High strength and low cost.
Alloy steel stronger and harder than carbon steel alloy steel is preferred for high stress applications such as axles torsion bars and drive shafts.
This metal is a good electrical and thermal conductor.
Aluminum and aluminum alloys are lightweight non ferrous metals with good corrosion resistance ductility and strength.
Stainless steel is a modern alloy that was developed in the early 1900 s.
Aircraft bodies and aerospace components are typically composed by lightweight materials such as aluminum titanium and magnesium alloys.
Its high strength hardness and workability makes stainless steel a useful metal type for a wide variety of uses.
It includes alloys 4130 4140 4340 es2100 and 8620.
