Aluminum Alloy Wire 5154 is certainly coming from aluminum alloy 5154. What is 5154 mean?
Let's start from aluminum alloy. You see aluminum is the predominant metal in Aluminium Alloy (or Aluminum Alloy), and typical alloys are copper (Cu), magnesium (Mg), manganese (Mn), silicon (Si), tin (Sn) and zinc (Zn). There are two principal classifications, named 1. Casting Alloys and 2. Wrought Alloys. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions.
The International Alloy Designation System is the most widely accepted naming scheme for Wrought Alloys. Each alloy is given a four-digit number. The first digit indicates the major alloying elements, the second — if different from 0 — indicates a variation of the alloy, the third and fourth digits identify the specific alloy in the series. For example, in alloy 3105, the number 3 indicates the alloy is in the manganese (Mn) series, 1 indicates the first modification of alloy 3005, and finally 05 identifies it in the 3000 series.
Now we know 5154 aluminium alloy is an alloy in the wrought aluminium-magnesium family (5000 or 5xxx series). As an Aluminium-Magnesium (Al-Mg) Alloy, it combines moderate-to-high strength with excellent weldability. 5154 Aluminium Alloy is commonly used in welded structures such as pressure vessels and ships. As a Wrought Alloy, it can be formed by rolling, extrusion and forging, but not casting. It can be cold worked to produce tempers with a higher strength but a lower ductility. It is generally not clad.
Alternate names and designations include AlMg3.5, N5, and A95154. The alloy and its various tempers are covered by the following standards:
