Benefits of Aluminum Tubing Aluminum presents manufacturers and end-users with several benefits over other materials, including Strong, but lightweight construction. Aluminum demonstrates an excellent strength-to-weight ratio.
Silicon alone in aluminum produces a nonheat-treatable alloy; however, in combination with magnesium it produces a precipitation hardening heat-treatable alloy. Consequently, there are both heat-treatable and nonheat-treatable alloys within the 4xxx series. Silicon additions to aluminum are commonly used for the manufacturing of castings.

Aluminium penetration in wheels was in the year 2000 for European vehicles about 30 to 35%, compared to largely more than 50% in USA and Japan. This is representing more than 14% of the average aluminium content of a vehicle and is expected to rapidly increase (foreseen 45% in 2005 and 70% ...
Infinitely recyclable and highly durable, nearly 75 percent of all aluminum ever produced is still in use today. Aluminum is 100 percent recyclable and retains its properties indefinitely. Aluminum is one of the only materials in the consumer disposal stream that more than pays for the cost of its own collection. More Facts and Statistics.
Aluminium (or aluminum) metal is very rare in native form, and the process to refine it from ores is complex, so for most of human history it was unknown.However, the compound alum has been known since the 5th century BCE and was used extensively by the ancients for dyeing. During the Middle Ages, its use for dyeing made it a commodity of international commerce.
