Experiments of Making Alloys using Daily-life Metals

Some Experiments based on real-life objects to make alloys or test them are:

Comparative Strength Test

Gather samples of different alloys such as pure metals like iron, copper, and aluminum, along with common alloys like steel (iron and carbon) and brass (copper and zinc). Use a tensile testing machine to subject each sample to increasing amounts of force until they break. Measure and compare the force required to break each sample. This experiment demonstrates how the addition of other elements to pure metals can enhance their strength and durability, as seen in alloys like steel.

Corrosion Resistance Experiment

Obtain samples of different metals and alloys, including pure metals like iron, copper, and aluminum, and alloys like stainless steel (iron, chromium, and nickel). Expose each sample to a corrosive environment, such as saltwater or acidic solution, for a set period. Observe and compare the extent of corrosion on each sample. This experiment highlights how alloying elements like chromium and nickel can improve a metal’s resistance to corrosion, as seen in stainless steel compared to pure iron.

Thermal Conductivity Demonstration

Prepare samples of different metals and alloys, including copper, aluminum, and brass. Place each sample on a heated surface, such as a hot plate, and measure the time it takes for a drop of water placed on top to evaporate. Compare the rate of heat transfer through each sample by observing the speed of water evaporation. This experiment illustrates how alloy composition affects thermal conductivity, with metals like copper exhibiting higher conductivity compared to alloys like brass, which contain less conductive elements like zinc.

Alloys are used in many aspects of our daily lives. They are found in everything from the jewelry we wear to the cars we drive. Alloys are also used in many industrial applications, such as construction and manufacturing. One of the most common alloys is steel. Steel is an alloy of iron and carbon. It is used in a wide variety of applications, including construction, manufacturing, and transportation. Steel is also used in many household items, such as appliances and furniture. In this article, we will learn in detail about various applications of alloys in daily life.
