The metal used in crumple zones varies by manufacturer. It depends on the metal used during the assembly and and or type of structure on the car.
Most commonly used on steel frames and unibodies is HSS or high strength steel. There are many alloys used in different control points on your car to control energy during a collision .
There may be several types used in different areas and some times different alloys overlapped in the same area to control factors found during a collision or rollover.
There are many hybrid metals now used in cars such as HSS, HCHS, Boron, and aluminum . Aluminum is also used in several alloy strengths in many cars.
Some of the metals may not be repaired . Some may not be allowed to be heated during repair most have special coatings and or corrosion protection applied to or mixed in with them when being formed and or manufactured.
You can find out specific information about your car by looking up your manufacturers repair procedures for collision repair on several web sites.
Good luck and be careful as many crush zones are designed to be replaced after collision . You may need special equipment such as a MIG welder or an Aluminum pulse welder , some parts are laser welded and othesr are chemically bonded or a cobination of these. many specialized tools and knowledge is required to replace these metal components.

What are the advantages of the crumple zone?
A crumple zone absorbs energy during impact.
How does a crumple zone protect you in a car crash?
The crumple zone crumples, absorbing some of the energy from the impact so that all of that energy doesn't crumple the passengers.
Who engineered the crumple zone in automobiles?
The first real credited design for a crumple zone was done by Engineer Béla Barényi at Mercedes in 1959
How does a crumple zone reduce the risk of injury?
A crumple zone is an area of the car specifically designed to fold up like an accordion upon impact. The action of bending the metal requires energy. As the metal crumples, it absorbs energy from the impact. This means that as more of the car crumples, more energy is absorbed by the car and not you. The less energy you absorb, the less likely serious energy will occur. The passenger compartment on the vehicle is designed to crumple either around passengers or not at all, maximizing the crumple zones of the car.
How do you protect an egg in a car crash?
Crumple zone
Why is it important for cars to have a crumble zone?
A crumple zone absorbs the impact, lessening the trauma on the occupancy on the vehicle.
What does a crumple zone protect?
The Passenger. By supplying a place in the structure of the frame to crumple in an accident, the force is absorbed and dissapated before it reaches the passenger compartment.
What are statistics regarding crumple zones?
The crumple zones of cars are normally at the front because it is estimated that 65% of the car impacts occur on the front side. The crumple zone is aimed at absorbing the impact of a crush to secure the passengers.
How do you manufacture a crumple zone?
To manufacture a crumple zone in a open wheel race car we create an aluminum box riveted together. The key is that the rivets will fail in a controlled manner absorbing the energy of the crash. In a road car you start by making the passenger compartment hugely strong. Then make the crumple zone weaker in a very careful way so that as it progressively collapses it absorbs the energy of the crash.
What is a crumple zone of a car?
The term crumple zone is a part of the car that takes the majority of the engergy during an accident. The objective is to make the car safer during an accident. If you watch crash test videos you will see the car fold up in the front or where ever the impact is. But you will also see a lot of pieces of the car go fling all over the place. that is an exaple of a crumple zone. the vehicle is taking most of the impact
Where is a crumple zone?
Typically, crumple zones are located in the front part of the vehicle, in order to absorb the impact of a head-on collision, though they may be found on other parts of the vehicle as well.
What will car absorb the energy and forces of the crash?
A car absorbs the energy and force of a crash in the crumple zone.
