Main Difference – Ductility vs Malleability
Ductility and malleability are properties related to deformation of metals. Ductility is the ability of a metal to undergo tensile stress. Malleability denotes the ability to undergo compressive stress.
These two remarkable properties are due to the unique metallic bonding found only in metals.

6. Complete these phrases..
1. Kevlar is used in bulletproof vests because it is capable of resisting severe impact.
2. Polypropylene is used inside crash helmets because it has the capability of absorbing impact and softening a blow to the head.
3. Nylon is commonly used in waterproof jackets because it has the capacity to withstand water and to prevent it from passing through.
4. Wood is rarely used nowadays for making a boat hull because it is incapable of stopping rocks from cutting into the hull.
Slide 45 - Diapositive
Proof is generally stronger than resistant:
A waterproof jacket is probably guaranteed to keep out all water, but a water-resistant jacket may not be.
