Question

Many pure metals like copper, iron and gold are very soft and as such are considered unsuitable for certain uses. Metallic objects around us such as cooking utensils, statues, ornaments, guns etc. are actually not made up of pure metals. Instead of pure metals, alloys are used in the design of most of the useful objects. Making alloys enhances the basic properties of a metal which is the primary constituent (metal) of an alloy.
Name an alloy used for welding two wires together in an electric circuit. Write its major constituents.

Hint:

Solder is an alloy of tin and lead used for joining electrical components. It has a low melting point, which makes it ideal for welding wires.

Answer 1

An alloy used for welding two wires together in an electric circuit is solder. It is commonly used for joining electrical components. Major Constituents of Solder:
- Tin (Sn): 60-70% - Lead (Pb): 30-40% This alloy has a relatively low melting point, making it easy to use for soldering electrical wires together. However, modern solders often use other elements like silver to reduce toxicity and improve strength.
