Brittle can be any solid material which can break easily like non-metal materials: CDs, DVDs, etc. Explanation: An element is said to be brittle if it is hard but breaks easily with little force. Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead. However, While within each layer of graphite the carbon atoms contain very strong bonds, the layers are able to slide across each other, making, Zinc is a lustrous bluish-white metal. Highly pure zinc (99.99 percent) is ductile; the so-called prime western grade (99.8 percent pure) is brittle when cold but above 100 C (212 F) can be rolled into sheets that remain flexible.
