Bells are not made of wood but of  metals because when they are banged they create good sound beacuse of their property of being sonorous.Non-metals do not posses this ability.

There are other objects meant to vibrate in a bell-like way that are not made of metal. The most bell-like in sound is an instrument or instruments called Angklung in Thai. ... Metals used for bells are specially designed alloys that make a nice ringing sound. Small bells may be made of glass or ceramic.Bells are made up of metals Rather than wood because according ... no voice will be produced and hence your bell will be of no use.bells are made of metal because they have a property os sonorous and they make sound but , wood are non - metal so they cant produce sound . Metals are sonorous ,i.e, metals have the property of producing ringing sound when struck.Therefore ,bells are made up of metals.

Introduction:

Bells have been an essential part of human culture for centuries. They are used for various purposes, such as religious ceremonies, musical performances, and signaling. Bells are typically made of metal rather than wood due to several reasons. In this article, we will explore the factors that make metal a preferred material for bells.

1. Acoustic Properties:
Metal produces a distinct and resonant sound when struck, making it ideal for bell manufacturing. The vibrating metal creates a strong and long-lasting sound that can travel over long distances. Wood, on the other hand, does not possess the same acoustic properties. It is not able to produce a sustained and clear sound like metal does.

2. Durability:
Metal bells are more durable and long-lasting compared to wooden bells. Wood is prone to decay, rot, and damage from insects and moisture. On the contrary, metals like bronze, brass, or iron are highly resistant to corrosion and can withstand harsh weather conditions. This durability ensures that the bell maintains its sound quality and structure for an extended period.

3. Tuning and Pitch Control:
Metal bells offer greater control over tuning and pitch. Bell makers can shape the metal to achieve specific frequencies and harmonics, allowing for precise musical notes. Wood, although it can be carved and shaped, does not offer the same level of control over tuning and pitch. The flexibility of metal makes it easier to create bells with specific musical tones and harmonies.

4. Aesthetics:
Metal bells often have a more visually appealing appearance compared to wooden bells. The shiny and reflective surface of metals like bronze or brass adds an aesthetic element to the bell. This is particularly important for bells used in religious or ceremonial settings, where visual appeal plays a significant role.

Conclusion:
In summary, bells are made of metal rather than wood due to their superior acoustic properties, durability, tuning control, and aesthetics. Metal bells produce a clear and resonant sound, withstand the test of time, allow for precise tuning, and offer an appealing visual appearance. These factors make metal the preferred material for bell manufacturing.
