Excellent corrosion resistance. Now comes the tricky part. Moderate to high strength, as well as good weldability and resistance to corrosion in marine environments. Great corrosion resistance, Aircraft parts, pump housings, structural applications, pump housings, impellers, High strength when treated. The term can apply to deformation from indentation, scratching, cutting or bending. Manganese is the major alloying element, Silicon’s addition lowers the melting point without producing brittleness, Filler alloy for structural and automotive applications. Magnesium, copper, and chromium. LM5 AL-Mg5Si1 51300 AG6 3058 514 … Heat-treatable, incredibly strong alloy. But say your specs call for more magnesium and other metals. Difficult to weld, as it’s subject to cracking. It is a silvery-white, soft, non-magnetic and ductile metal in the boron group. The abundance of aluminium decreases relative to other elements at greater depths into Earth's mantle and beyond. Moderately high strength and highly corrosion-resistant. Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. Excellent corrosion resistance. Among the strongest aluminium alloys. Aluminum alloys are economical in many applications. When it comes to choosing the right grade of aluminum for a particular application, it’s best to play it by the numbers. Heat treatable, with moderately high strength. Practically a miracle metal, aluminum is almost as popular as steel. What is the typical hardness for MIL-A-8625, Type III, Class 2 coatings? Architectural and structural, marine craft, other marine applications, auto and cycling frames and components, Good corrosion resistance and precipitation hardening, Heat treatable, highly formable, weldable. Chat Now Send Inquiry; Hardness - nde-ed.org. Does not need heat treating. Hardness of Aluminium Alloy – 6061. Of course, this is more than just an aluminum strength chart -- be sure to check out all the other standouts by corrosion resistance, formability, and so on. First, why use aluminum? ), Aluminum Grades Chart PDF -- Types of Aluminum. The digits tell you the alloy’s chemical composition. Highest strength of non-heat-treated alloys. The main alloy ingredients of 6061 aluminum are magnesium and silicon. It is also capable of being anodized, adding a layer of protection for finished parts. The Aluminum Association has devised a four-digit alloy classification system to separate alloy families (for example, 3xxx) for wrought alloys and a three-digit plus decimal system (for example 2xx.x) for cast alloys. An example of how to use this chart to your benefit is this: If you’re looking for the strongest aluminum alloy to use in building aircraft, you probably want copper as an alloying metal. There are more than 500 aluminum alloys registered with the Aluminum Association. When it comes to choosing the right grade of aluminum for a particular application, it’s best … You can go to your chart and start with #2 on the wrought composition section because it contains alloys with copper as the main alloying metal. Good combination of strength and toughness, but lower atmospheric corrosion resistance than many other aluminum alloys, Moderate to high strength, as well as good weldability and resistance, Marine craft and applications, U.S. military’s Bradley. (Is aluminum ductile in general? The specifications, properties, classifications and class details are provided for aluminium and aluminium alloys. Very simply put, engineers use either heat treatment or mechanical methods (sometimes both) to develop wrought and cast aluminum alloys. High, Copper used as the principal alloying element and can be, strengthened significantly through solution heat-treating. Hardness Tables Mohs Hardness Scale. Aluminium 6061-T6 is a subcategory of the 6061 aluminium alloy, one of the most widely used aluminium alloy categories in the world.The alloy is appreciated because of its versatile performance and all-around mechanical properties.The “T6” part of the 6061-T6 name indicates the type of the tempering treatment process that this aluminium alloy type undergoes.
