Properties of Aluminium
Aluminium is a lightweight, strong, and durable metal that is widely used in various industries. Some of the properties of aluminium are:
1. Modulus of Elasticity is Fairly Low:
Aluminium has a relatively low modulus of elasticity compared to other metals. This means that it is more flexible and less stiff than materials like steel. However, this property also makes it more susceptible to deformation and bending under stress.
2. Wear Resistance is not Very Good:
Contrary to the statement given in the question, the wear resistance of aluminium is not very good. It has a relatively low hardness and can easily scratch, scuff, or dent under abrasive or impact forces. Therefore, it is often coated or treated with other materials to enhance its wear resistance.
3. Fatigue Strength is not High:
Aluminium has a low fatigue strength, which means that it can fail or crack under cyclic loading or repeated stresses. This property makes it less suitable for applications that require high durability and long-term reliability.
4. Corrosion Resistance is Good:
Aluminium has a natural oxide layer that forms on its surface when exposed to air or water. This layer provides a protective barrier against corrosion, rust, or tarnishing. Therefore, aluminium is often used in applications that require resistance to environmental or chemical exposure.
Conclusion:
In conclusion, the false statement about properties of aluminium is option 'B' that the wear resistance of aluminium is very good. Aluminium has a relatively low wear resistance and is susceptible to scratches, scuffs, or dents under abrasive or impact forces.
