Ducility is an intensive property because it does not depend on the quantity of the material being tested. Ducility refers to how easily a material can be deformed under tensile stress without fracture, and this property remains constant regardless of the sample size.
An extensive property is a property that depends on the size or extent of a system. Examples include mass, volume, and energy.
Area is an extensive property.
Mass is not an intensive property, it is an extensive property, i.e. the mass of a system made of two parts A and B is equal to the mass of A plus the mass of B. An intensive property (e.g. pressure or temperature) is one in which the value of the property for the entire system is equal to the value of the property for any of the subsystems. So, you probably wanted to ask why mass is an extensive property. This is a consequence of the law of gravity and of the fact that forces add up to make a resultant force. The total gravitational force upon a body X by two other bodies A and B is the sum of the force exerted by A and the force exerted by B. It's as if we have a combined body with the mass of A plus the mass of B, and thus mass is extensive.
is radioactivity extensive or intensive or chemical property
Malleability is an intensive property.
Ductility is a physical property, because it refers to an easy change in the shape of a solid substance; no chemical change occurs during such changes of shape.
Width is an extensive property.

I consider that the term "use" for an extensive property is not adequate.

An extensive property is a property that changes when the size of the sample changes, weight would change.
Circumference is an extensive property.
