It is convenient to divide aluminum alloys into two major categories: wrought compositions and cast compositions. A further differentiation for each category is based on the primary mechanism of property development. Many alloys respond to thermal treatment based on phase solubilities.

2024年8月8日 · Our expert mechanical engineer will guide you through the eight series of aluminum alloys, revealing their strengths, weaknesses, and how they shape our modern world. Get ready to discover the hidden wonders of this versatile metal! Aluminum’s unique properties make it a versatile material in metal fabrication and manufacturing:

2024年9月29日 · Explore the chemical composition of aluminum alloy series, including 2000, 3000, 4000, 5000, 6000, and 7000 series. Learn how alloying elements like copper, manganese, silicon, magnesium, and zinc influence strength and corrosion resistance in various applications.

Table 1 shows the meaning of the first of the four digits in the alloy designation system. The alloy family is identified by that number and the associated main alloying ingredient(s), with three exceptions:

4xxx series Aluminum / Silicon alloys (Silicon ranging from 0.6% to 21.5%) Properties: ! Excellent weldability and fair weld strength of 120 MPa ! Moderate strength ! Has heat and non-heat-treatable properties ! Excellent corrosion resistance Applicaons:! Used as filler material ! Welding and brazing wire ! Forged engine pistons

2005年5月17日 · Aluminium is most commonly alloyed with copper, zinc, magnesium, silicon, manganese and lithium. Small additions of chromium, titanium, zirconium, lead, bismuth and nickel are also made and iron is invariably present in small quantities. There are over 300 wrought alloys with 50 in common use.

Listed herein are designations and chemical composition limits for aluminum and aluminum alloys in the form of powders as registered with the Aluminum Association. This list is maintained by the Technical Committee on Product Standards (TCPS) of the Aluminum Association.

Rare and expensive a century ago, aluminium has since been identified as the most common metal on earth, forming about eight percent of the earth's crust. It is the third most plentiful element known to man. Only oxygen and silicon (sand) exist in greater quantities.

Alloys of the 5XXX series (Al-Mg) are the strongest non-heat-treatable aluminum alloys, and in most products, they are more economical than alloys of the IXXX and 3XXX series in terms of strength per unit cost. Magnesium is one of the most soluble elements in aluminum, and when

Aluminum is a lightweight metal with a den-sity of 2.70 g/cm3 (0.1 lb/in.3) and a moderately low melting point of 655 C (1215 F). Since it has a face-centered cubic crystalline structure, the formability of aluminum and aluminum alloys is good. The good formability is further aided by its rather low work-hardening rate.
