How many classifications of aluminum are there?

Aluminum comes in three basic types: 1100, 3003, and 6061. The grade of the aluminum will determine the end-use application and price point. For example, 1100 is a lower-cost material than 6061 but cannot be used for high-temperature applications like cooking utensils or pot lids.

What are the most common alloys of aluminum?

The most common alloying elements for aluminum include copper, magnesium, manganese, silicon, tin, and zinc. The term “common alloy” has been applied to three families of aluminum alloys, all of which fall in the category of non-heat treatable grades.

How are alumium alloys classified and designated?

Aluminum alloys usually have a 4-digit designation. The first digit designates purity or alloy type. The second digit indicates modifications of the alloy. Only in 1xxx series the third and fourth digits indicate the purity.

How many Aluminium alloys are there?

Currently there are over 400 wrought aluminum and wrought aluminum alloys and over 200 aluminum alloys in the form of castings and ingots registered with the Aluminum Association.

What does the 6061 mean in aluminum?

precipitation-hardened aluminium alloy
6061 (Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called “Alloy 61S”, it was developed in 1935.

What is 300 series aluminum?

The 300 series is generally classified as an Aluminum-Silicon alloy grade, which probably accounts for 90% of the production aluminum castings. Most aluminum wheels, steering knuckles, control arms and cylinder heads use the A356 alloy, as do many cylinder block designs.

What is 7000 series aluminum?

The 7000 series alloys (Al-Zn-Mg-(Cu)) have the highest strength of all aluminum alloys. The 7005 Al-4.0-5.0Zn-1.0-1.8 Mg) and 7075 (Al-5.1-6.1Zn-2.1-2.9 Mg-(1.2-2.0Cu)) alloys are used to produce frames. 7075 aluminum alloy is also widely used in the aero industry.

What is the strongest Aluminium alloy?

developed an ultra-strength alloy called 7068-T6511 – commonly known as Tennalum® 7068. With a yield strength of 99 KSI (683MPa) it has the highest mechanical strength of all commercially available aluminum alloys (2.5 times stronger than 6061, and 35% stronger than 7075) and exceeds that of many steels.

What grade of aluminum is the strongest?

Grade 7000

It is an extremely high strength alloy; the strongest of all commercial grades of aluminium. In fact, grade 7075 aluminium is stronger than many types of mild steel.

What is 7000 series aluminum?

The 7000 series alloys (Al-Zn-Mg-(Cu)) have the highest strength of all aluminum alloys. The 7005 Al-4.0-5.0Zn-1.0-1.8 Mg) and 7075 (Al-5.1-6.1Zn-2.1-2.9 Mg-(1.2-2.0Cu)) alloys are used to produce frames. 7075 aluminum alloy is also widely used in the aero industry.

What’s the difference between 6061 and 7075 aluminum?

Both 6061 aluminum and 7075 aluminum are heat treatable. It is interesting to note that even though 7075 aluminum is much stronger than 6061 aluminum, it melts at a slightly lower temperature. Because 6061 aluminum has a higher thermal conductivity than 7075 aluminum, it can be a better choice for certain applications.

What does T6 mean in aluminum?

The T6 refers to the temper or degree of hardness, which is achieved by precipitation hardening. This grade has a good strength-to-weight ratio and is also heat-treatable. With great formability and weldability, it is used for engineering and structural applications, boats, furniture, and more.

What is 1000 series aluminum used for?

1000 Series is the most pure of aluminum—required to have 99% minimum aluminum. It is weldable but under narrow guidelines. Because of its superior corrosion resistance, it is mainly used in specialized chemical tanks or conductive bus bars.

What is 3000 series aluminum used for?

3000 series Aluminum alloys are Aluminum alloyed with manganese. They have higher strength than pure aluminum while maintaining good formability and corrosion resistance. These alloys are not heat treatable and are suitable for anodizing and welding.

What is 2000 series aluminum used for?

2000 Series aluminum alloy covers 2024, 2A16(LY16), 2A02(LY16). 2000 series aluminum alloy is with very good performance on hardness, Cu element percentage is from 3-5%, 2000 series aluminum alloy mainly used to produce airplane, rarely in other purpose use.

What is 8000 series aluminum used for?

1.1 This specification covers 8000 series aluminum alloys fabricated into round wires in annealed or intermediate tempers suitable for stranding into conductors or for solid single conductors, usually to be insulated.

What is 6000 series aluminum used for?

Uses of this form of 6000 series alloy include applications from transportation, to infrastructure to more every day uses like fly fishing reels, firearm suppressors, non-flight critical aircraft components and automotive components. 6061 is available in many forms, including extrusion sheets, and forgings.
