Q:

What are examples of ductile materials?

A:

Quick Answer

Aluminum, copper, tin, mild steel, platinum and lead are examples of ductile materials. Ductile materials can be stretched without breaking and drawn into thin wires. Ductility is an important property for manipulating these metals by hammering, drawing or rolling. It makes possible their use for making electrical wires, pipes, plates and other metalworks.

Ductile materials have varying degrees of ductility depending on temperature, metallic bonds, material constituents and working process to which the material is subjected. Varying the temperature can either make a material more or less ductile. For example, lead and tin are ductile while cold, but they become brittle when heated to their melting points. Therefore, the temperature at which a metal transitions from being ductile to brittle must be considered in the selection of materials in addition to knowing the mechanical processes to which is to be subjected.

Materials are also highly ductile because of their characteristic metallic bonds. As such, metals are generally ductile, but the composition of these metallic materials is not always pure. They have alloying constituents, which affects ductility. For example, increasing the carbon component of steel decreases ductility. Another example is zinc, which is brittle at low temperature, but when heated up and alloyed with copper to form brass, it becomes somewhat ductile as well.

  • Q:

    What is the composition of a solder?

    A:

    Traditional soldering material is primarily composed of lead and tin, while modern lead-free solder is made out of a combination of several metallic elements, including silver, copper, bismuth, zinc, indium and antimony. The proportion of these metals in a soldering alloy determines the properties of the solder.

    Where can you find zinc?

    A:

    Zinc is usually found in mineral deposits that include copper, lead, iron and other base metals. Its primary ore is sphalerite, which accounts for about 95 percent of zinc produced worldwide. China is the largest zinc producer, followed by Peru, Australia, India and the United States.

    What are some zinc applications?

    A:

    Zinc is used to galvanize other metals, such as iron and steel, to prevent rusting, and several metal alloys, such as brass (zinc alloyed with copper), use zinc. Zinc is also used to make zinc oxide. Another use of zinc is to make pennies in the United States.

  • Q:

    Which metals are poor electrical conductors?

    A:

    Although metals are supposed to be good conductors of electricity and heat, metals like mercury, lead, alloys of iron and chromium, titanium and stainless steel are poor conductors when compared to silver, copper and gold. For example, stainless steel 310 has an electrical conductivity of 1.28 x 10E6 siemens/m, while mercury's electrical conductivity is 1.1 x 10E6 siemens/m. However, silver, which has the highest electrical conductivity of all metals, has a n electrical conductivity of 62.1 x 10E6.
