Aluminum
Aluminum alloys are materials made up of two or more metals. They are designed with specific purposes in mind, usually by industries that have requirements for their components. Some alloys were developed for corrosion resistance, and others for tensile strength, while some maintain their integrity

and straightening operations; however, hot forming fully heat-treated materials is difficult. Generally, aluminum formability increases with temperature. Recently developed aluminum alloys can provide nearly custom-engineered strength, fracture toughness, fatigue resistance, and corrosion resistance

Corrosion Resistance
samples must last 336 hours in the salt spray chamber before significant corrosion occurs. Testing was performed on six common alloys: 2024-T3, 3003-H14, 5005-H34, 6061-T6, 6063-T52, and 7075-T6. Ten aluminum coupons (4"x 4") of each alloy were anodized to 0.7 mil under Type II conditions using

Connectors stand up to corrosion
). Magnesium Aluminum. Zinc Chromium Iron Cobalt. Nickel Lead Copper Mercury. Silver Platinum Gold. () More noble (cathodic). Metals at the top of the list of electromotive elements are anodic. They're more likely to give up electrons during the corrosion process to the more cathodic metals below them
