What are common aluminium alloys designations?

There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions.

What is the designation of Al alloy?

The 2xxx, 6xxx, and 7xxx series wrought aluminum alloys are heat treatable and the 4xxx series consist of both heat treatable and non-heat treatable alloys. The 2xx. x, 3xx. x, 4xx….Understanding the Aluminum Alloy Designation System.

How are aluminum alloy compositions designated?

Generally, a four-digit numerical designation is used to specify aluminium and its alloys (Table 1), where first digit denotes the principal alloying element except AA1XXX series, which stands for purity of aluminium. The fourth digit is used after decimal point and it is 1 for cast ingot and 0 for casting.

What aluminum alloy is used for casting?

A380 Aluminum Alloy The most popular alloy for aluminum die casting is A380. We use A380 because it has demonstrably the best combination of physical and mechanical properties for casting, including being lightweight, very strong at high temperatures and corrosion resistant.

Which is better aluminum alloy or stainless steel?

Stainless steel is stronger, while aluminum is lighter. Aluminum conducts heat much better than stainless steel, while stainless steel is less reactive with food. Aluminum is cheaper and easier to clean, but stainless can be formed into shapes.

What is 6000 series aluminum used for?

Containing manganese and silicon, 6000 series aluminium’s structure allows the alloy to be solution heat-treated which improves the strength of the material. The alloy is used in welding fabrication and to produce structural components.

What is 4000 series aluminum used for?

The 4000 series of alloys contain quite high silicon contents, and are typically not used for extrusion purposes. They are popular for a variety of welding wire and brazing wire applications. Their uses include sheet, forgings and welding and brazing products.

What is the most common aluminum alloy?

3003 aluminum
3003 aluminum is the most widely used aluminum alloy. It has excellent workability and corrosion resistance and reacts well to finishing such as laminating or anodizing. It is a non-heat treatable metal. It is typically used for pressure vessels, garage doors, builder’s hardware, and more.

Is Aluminium good for casting?

One of the most significant benefits of aluminum die casting is that it creates lighter parts—with more surface finishing options than other die cast alloys. Moreover, cast aluminum is versatile, corrosion resistant; it retains high dimensional stability with thin walls and can be used in almost any industry.

What is the difference between aluminum alloy and cast aluminum?

Cast vs. Cast alloys of aluminum are those which contain > 22% alloying elements by composition, whereas wrought alloys of aluminum contain ≤4%. This may seem like a simple difference, but the percentage of alloying elements has a huge impact on material properties.

What metal is compatible with aluminum?

While many people worry that stainless steel fasteners, such as screws, bolts, nuts, or host of other options, won’t work with aluminum due to the risk of galvanic corrosion between the two very different metals, the truth is that stainless steel is the metal of choice for fasteners to secure your aluminum materials.

Which is expensive stainless steel or aluminum?

Aluminum is a more costly than stainless steel if you look at price based on weight. But, if you look at price by volume, Aluminum is more cost effective because you get more product.

What are the alloy and temper designations for aluminum?

SYSTEMS FOR DESIGNATING alumi- num and aluminum alloys that incorporate the product form (wrought, casting, or foundry ingot), and its respective temper (with the exception of foundry ingots, which have no temper classification) are covered by American National Standards Institute (ANSI) standard H35.1. The Alu-

What are the four digit designations for aluminum?

Designation System A four-digit numerical designation system is used to identify wrought aluminum and aluminum alloys. As shown below, the first digit of the four-digit designation indicates

What’s the difference between wrought and cast aluminum?

The wrought and cast aluminums have different systems of identification; the wrought having a 4-digit system, and the castings having a 3-digit and 1-decimal place system. We shall first consider the 4-digit wrought aluminum alloy identification system.

What does a capital letter mean on an aluminum alloy?

A capital letter prefix indicates a modification to a specific alloy. Example: Alloy – A356.0 the capital A (Axxx.x) indicates a modification of alloy 356.0. The number 3 (A3xx.x) indicates that it is of the silicon plus copper and/or magnesium series.
