There are several metals that have a certain span of flexibility. It depends on the purpose the metal is being used for, and the shape the metal takes on. Aluminum, copper, and sterling silver, all have uses that require some flexibility. Springs made of steel can be considered flexible.
METAL
There are three main types of air ducts: sheet metal, pre-insulated, and flexible duct work. Sheet metal air ducts can be made of galvanized steel or aluminum, and may be insulated inside or outside with fiberglass. There are pre-insulated air ducts, which are relatively inexpensive to install, made of fiberglass duct board, polyurethane foam panels, or phenolic foam panels. Air ducts can also be flexible ducts, made of flexible plastic over a wire coil.
Usually in the industry, we call it metal conduits. Metallic conduit is stronger, more durable, and more fire-resistant than non-metallic conduit. It is often used in industrial, commercial, and hazardous environments.

Depends on what shape they are manufactured in. E.g. springs, which are very flexible.
The word for a flexible strand of metal is "wire."

METAL
Flexible is a property of metal and not gases. Argon is a gas and cannot be flexible.
a flexible piece of metal
Yes it is. Rubber can be bend wherelse the metal cannot!
Non-flexible sheet metal piping
Flexible pipes can protect against somemovement.
is it permitted to use flexible metal conduit over 6 ft in length as a grounding means
Of course a paper cup would be more flexible. Nails are hard to bend.
No, mercury is not flexible. It is a liquid metal at room temperature, which means it can flow and change shape, but it does not have the ability to flex or bend like a solid material.
Copper is a metal that can be flexible, shiny, and has a brownish hue. Its natural color is a shiny orange-brown, and it is known for its malleability, making it easy to shape and form into various objects.
