Usually in the manufacture of steel.
Boron has several uses, such as in the production of glass, ceramics, and detergents. It is also used in some pesticides and in nuclear reactors as a neutron absorber. Additionally, boron is used in the manufacture of high-strength materials like boron fibers and composites.
you use it in technology and car care you use the steel ruler for straight lines for wood and plastic and other things.
Use exactly what the manufacture of your car recommends and nothing else.
He must have nerves of steel.The steel marbles are usually ball bearings.I hope this "smart car" has a steel frame.
Because it lowers the weight of the car.
Boron's super powers include being an excellent neutron absorber in nuclear reactors to control reactions, a key component in the manufacture of high-strength materials like borosilicate glass (e.g., Pyrex), and its use in a range of electronic devices due to its semiconductor properties.
Stainless steel, like the Delorean.
air craft
if you mean the exhaust pipes it depends on the car. older cars were usually made of steel. now they use stainless steel alot.
You can if the manufacture recommends that particular weight of oil.
For automotive use steel is inexpensive and easy to form. Kitchen sinks use stainless steel because it won't rust but it is harder to form.
