Types of Aluminium Alloy Sheets: T Sheet, QQA/ 'T' Sheet, QQA/ 'O' Sheet
Aluminium alloy sheets are widely used in various industries due to their excellent properties such as high strength-to-weight ratio, corrosion resistance, and durability. However, not all aluminium alloy sheets are created equal. There are different types of aluminium alloy sheets available in the market that cater to specific applications and requirements.
In this section, we will discuss the three most common types of aluminium alloy sheets: T sheet, QQA/ ‘T’ sheet, and QQA/ ‘O’ sheet. Each type has its unique characteristics that make them suitable for specific applications.
T Sheet
T sheet is a heat-treated aluminium alloy sheet that has been solution heat-treated and artificially aged. This process results in a material with improved strength and hardness compared to non-heat-treated alloys. T sheet is commonly used in aerospace applications where a high strength-to-weight ratio is critical.
One example of an application where T sheet is used is in aircraft structural components such as wing skins, fuselage frames, and landing gear parts. The use of T sheet allows for lighter weight structures without compromising on strength.
QQA/ 'T' Sheet
QQA/ ‘T’ sheet is another type of heat-treated aluminium alloy sheet that has been solution heat-treated and artificially aged. However, unlike T sheet which follows AMS specifications (Aerospace Material Specification), QQA/’T’ follows QQ-A (Quick Quality Aluminum) specifications.
QQA/’T’ sheets have similar properties to T sheets but may have slightly different mechanical properties due to differences in the manufacturing process. They are commonly used in aerospace applications where AMS specifications are not required.
QQA/ 'O' Sheet
Unlike T sheet and QQA/’T’, QQA/’O’ (annealed) sheet undergoes an annealing process instead of a heat treatment process. Annealing is a heat treatment process that involves heating the material to a specific temperature and then cooling it slowly to make it softer and more ductile.
QQA/’O’ sheets are commonly used in applications where formability is critical, such as in the automotive industry for body panels and trim parts. They are also used in architectural applications for roofing, siding, and decorative elements.
Types of Aluminium Alloy Sheets: H or H Sheet
There are different types available in the market. Each type has its own unique properties and applications. One of the most common types of aluminium alloy sheets is the H or H sheet.
What is an H or H Sheet?
An H or H sheet is an aluminium alloy sheet that has undergone a strain-hardening process. This process involves subjecting the material to high temperatures and then rapidly cooling it down to increase its strength and hardness.
The letter “H” in the name stands for “strain-hardened,” while the number following it indicates how much strain hardening occurred during the process. For instance, an H14 sheet has undergone a moderate amount of strain hardening, while an H18 sheet has undergone more severe strain hardening.
Properties of H or H Sheets
One of the main advantages of using an H or H sheet is its increased strength and hardness compared to other types of aluminium alloys. This makes it ideal for applications that require high mechanical performance, such as aerospace components, automotive parts, and construction materials.
Another advantage of using an H or H sheet is its excellent corrosion resistance. Aluminium alloys naturally form a protective oxide layer on their surface when exposed to air, which helps prevent corrosion from occurring. However, this layer can be damaged by exposure to certain chemicals or environmental conditions. An H or H sheet’s increased hardness and strength make it less susceptible to damage from these factors.
