Alloys are used because they are often harder than pure metal. Making alloys usually involves mixing one harder element with a metal to create a stronger item. More » Business & Finance Industries

To read a metal gauge thickness chart, determine the type of metal and the metal's gauge. Locate the gauge in the first column. Follow that row to the right to the column that indicates the metal's type. That column also... More » Science Measurements

Alloys are harder than pure metals because their molecular structure prevents the metal atoms from sliding over one another. Conversely, alloys have lower electrical and thermal conductivity than pure metals. More » Science Chemistry

A pure metal is a substance that contains atoms of only one type of metallic element, such as aluminum, gold, copper, lead or zinc. Most metals very rarely, if ever, appear in their pure form in nature and instead must b... More » Science Chemistry

Metal alloys, which are a mixture of metal and at least one other substance, are used because they are more suited for a particular task than a pure metal is. Metal alloys are typically either harder, stronger, lighter o... More » Science Chemistry Solutions & Mixtures

Niobium is used as an alloying agent in carbon and alloy steels and in non-ferrous metals. It is also used in jet engines and rockets. This element has superconductive properties and is used in superconductive magnets. T... More » Business & Finance Industries

Stick welding is a welding process that uses electric current and an electrode to form an electric arc that joins different metals. The electric arc melts the electrode and the metal, forming a joint. More » Business & Finance Industries
