Does the material used for a fuse wire need to have a low or a high melting point - a low or high ductility - a low or high resistivity?
The material for the fuse wire should have low resistance and a low melting point. Ductility is a incidental factor.
As the current flow nears the fuse rating, the high current flow causes the wire to heat up quickly. It then melts, opening (breaking) the circuit. This is how the fuse limits the amount of current that can flow through a circuit.

What is specific resistance and melting point of fuse?
low resistivity and low melting point.
Which of these properties would be more likely to be associated with a metal than a nonmetal?
Examples: malleability, ductility, thermal conductivity, electrical resistivity, solid state, magnetism, high melting point, etc.
Does uranium have a physical properties?
Of course: density, melting point, boiling point, electrical resistivity, thermal conductivity, hardness, ductility, crystal structure, lattice parameter, shear modulus, other mechanical properties, radioactive properties, etc.
What is neons ductility?
Neon is a gas, and the concept of ductility applies to malleable solids. The 'melting point' of neon is about 25 Kelvin.
What material is used to make a fuse wire?
The material suitable for making a fuse wire should have a low melting pt. so that it can easily melt and cut off the flow of current and save the electrical appliance...
What are 6 physical properties a physical substance may posses?
Examples: density, thermal conductivity, electrical resistivity, thermal expansion, ductility, malleability, hardness etc.
What is the melting point for reamer?
A reamer is a tool, not a material. The melting point would depend on what material the reamer is made of.
9 specific properties of matter?
It is important to remember the properties of matter. Brittleness, hardness, luster, solubility, malleability, ductility, elasticity, flexibility, and porosity are the properties of matter.

Examples: melting point, ductility, malleability, hardness etc.,
When a material is melting the temperature?
When a material is melting, the temperature is likely to be increasing. That or the temperature is just above the material's melting/freezing point.
What are the 6 quantitative properties of matter?
Examples: density, melting point, boiling point, refractive index, thermal conductivity, electrical resistivity.
What is melting point depression?
This is the modification of melting (freezing) point due to impurities in the material.
