Aluminum is a light metal, about the third of the density of steel, copper, and brass. Aluminum has good corrosion resistance to common atmospheric and marine atmospheres. Its corrosion resistance and scratch resistance can be enhanced by anodizing. Aluminum has high reflectivity and can be used for decorative applications.
Mar 12, 2019 Aluminum, atomic number 13, is a soft metal that makes up about 8% of the contents of the Earth's crust. The 3rd most abundant element, right after oxygen and silicon, aluminum is readily available. Because aluminum is a soft metal, different alloying elements are used to make aluminum plate, sheet, and bar products.
预计阅读时间：6 分钟Jul 27, 2017 Most cast aluminum engine blocks are made from one of three alloys: 319, A356 or A357. The 319 alloy is 85.8% to 91.5% aluminum, 5.5% to 6.5% silicon, 3% to 4% copper, 0.35% nickel, 0.25% titanium, 0.5% manganese, 1% iron, 1% zinc and 0.1% magnesium.

作者: Larry Carley6061 aluminum is the most commonly used aluminum alloy. It is specified in most any application due to its strength, heat treatability, easy machinability, and weldability. It is also capable of being anodized, adding a layer of protection for finished parts. The main alloy ingredients of 6061 aluminum are magnesium and silicon. 6061-T6 Aluminum.
Aluminum is a low melting point metal, therefore microstructural stability (and consequently creep) is an important issue even for near ambient temperature. Many common structural aluminum alloys are precipitation strengthened at heat treatment temperatures on the order of 423 K, implying that the service temperature must be considerably lower.

Aluminum conductors consist of different alloys known as the AA-1350 series and AA-8000 series. AA-1350 has a minimum aluminum content of 99.5 percent. In the 1960s and 1970s, due to the high price of copper relative to aluminum, this grade of aluminum began to be popularly used for household wiring.
Though the aluminum alloy also contain many similarities with low weight, it is still used in the manufacturing of diesel engine blocks because their internal stresses are higher. Grey cast iron contains 2.5 – 4 % of carbon, 1 -3 % of silicon, 0.2 - 1% manganese, 0.02 - 0.25 % of sulfur, and 0.02 - 1 % of phosphorus.
