To correctly identify the statement that is true, we need to understand the designation systems for cast and wrought aluminium alloys.
1. Cast Aluminium Alloys:
Cast aluminium alloys are primarily used in applications where high strength and good castability are required, such as automotive parts, machinery components, and aerospace applications. They are specified using a four-digit system.
2. Wrought Aluminium Alloys:
Wrought aluminium alloys are typically used in applications where high strength, good formability, and excellent corrosion resistance are desired, such as structural components, consumer products, and transportation industries. They are specified using a five-digit system.
Therefore, the correct statement is:
a) Cast aluminium alloys are specified by a four-digit system while wrought alloys by a five-digit system.
This means that option 'A' is the correct answer.
Explanation:
The designation systems for cast and wrought aluminium alloys are specified by the Aluminum Association (AA) in the United States. These systems provide a standardized way to identify and classify different aluminium alloys based on their composition and properties.
1. Cast Aluminium Alloys:
Cast aluminium alloys are designated using a four-digit system. The first digit represents the major alloying element or a group of alloying elements. The second digit indicates the modification of the alloy. The third digit represents the specific alloy within the series. The fourth digit indicates the variation of the alloy.
For example, the cast aluminium alloy A356.0 represents an alloy with silicon as the major alloying element (3xxx series), unmodified (0 modification), and a specific alloy variant (A356.0).
2. Wrought Aluminium Alloys:
Wrought aluminium alloys are designated using a five-digit system. The first digit represents the major alloying element or a group of alloying elements. The second digit indicates the modification of the alloy. The third digit represents the specific alloy within the series. The fourth and fifth digits indicate the variation of the alloy.
For example, the wrought aluminium alloy 6061 represents an alloy with magnesium and silicon as the major alloying elements (6xxx series), unmodified (0 modification), and a specific alloy variant (6061).
In summary, cast aluminium alloys are specified by a four-digit system, while wrought aluminium alloys are specified by a five-digit system. This differentiation helps in identifying the type of alloy and its intended application.
