Main Question or Discussion Point

Is there any materials that is elastically solid (ductile that can be shaped into thin wires) at low temperatures but liquid at room temperatures?

Mercury maybe depending on how low the temperature.

woods metal is 70C mp. there are others all a few tens of degrees above room temp

As was stated mercury -39C mp

Is there any material? Metal has a high melting point, it cannot be.

Is the material electrically conductive ?
What colour is it ?
Does it smell ?
Where did you find it ?
What do you want to use it for ?

The metal elemental Gallium melts at a temperature of 29.76 °C

The material necessary be nontoxic.
It must be viscous at liquid states.
I prefer an electrically conductive material and Non-newtonian.

The reason why i wanted a material that is liquid at room temperature but ductile at its solid state is because i wanted to produce a very small pipe filled with that liquid. Is it possible for a wire-material to electroplate it with aluminum or other metal below its melting point? so that when it is heated to room temperature, i have a pipe filled with viscous liquid?

Galinstan is a nontoxic alternative for Mercury in thermometers. These are generally not compatible with aluminum, but you'll need to do some research to see what metals they are compatible with. I would not attempt any electroplating - simply get tubes of compatible metals of the correct size and fill. You have limited choices for metals or alloys that are liquid at RT.
