Which of the following materials can be used for making patterns?1. Al...
Explanation:
A pattern is a model or replica of the final product which is to be casted. It is used to create a cavity in the mould, into which the molten metal will be poured. The pattern should be strong, rigid, and easily detachable from the mould.
The materials that can be used for making patterns are:
1. Aluminium
- It is a lightweight and corrosion-resistant material.
- It is easy to machine and can be easily casted.
- It can be reused many times.
2. Wax
- It is a low melting point material.
- It can be easily moulded and shaped.
- It is mainly used for making small and intricate patterns.
3. Mercury
- It is a liquid metal at room temperature.
- It can be used for making small and intricate patterns.
- It is toxic and should be handled with care.
4. Lead
- It is a soft and easily mouldable material.
- It can be used for making small and intricate patterns.
- It is toxic and should be handled with care.
Therefore, the correct answer is option D, i.e., 1, 2, and 3 materials can be used for making patterns.
