Bronze does not rust the way that iron does, bronze will corrode, but at a much slower rate than iron.
Steel will corrode as the iron in it is more reactive than copper.
Titanium is more rare than iron; also is more difficult to prepare titanium from ores.
Cast Iron does not rust or corrode as steel can
The density is a physical property not a change.
You can buy a titanium flat iron online on sites like beyas.ca, rylees and folica. Those are trustworthy so you'll get good customer service and a warranty. A professional titanium flat iron is the Karmin Titanium, it makes hair really shiny and straight and does the job faster than others. :)
As pennies are not made of iron, they cannot rust under any circumstances.However they can corrode. The copper shell will produce a green corrosion product, the zinc core can corrode completely away as a transparent water soluble corrosion product. This corrosion will be very slow in plain water (much slower than iron rusts in water) but will be much faster if an acid is added to the water.
I list them in order of heaviest to lightest:Gold, Silver, Iron, Titanium. Gold has no ore and ores are always less dense than the metal.
The melting point of Titanium is 1941 K, 1668 °C, 3034 °F whereas for iron it is 1811 K, 1538 °C, 2800 °F. So, yes melting point of iron is less than Titanium.
they are both gay, so it doesnt matter
NO!!! Because they are made of copper NOT iron.
Because of the cost
