Aluminum (Al)

Aluminum is a lightweight, soft, low-strength metal that can easily be cast, forged, machined, formed, and welded. It is suitable only in low-temperature applications, except when alloyed with specific elements. Commercial aluminum alloys are classified into two groups, wrought alloys, and cast alloys. The wrought alloy group includes those alloys which are designed for mill products … Read more

Aluminum Brazing

a. Aluminum Brazing. Many **aluminum alloys **can be brazed. Aluminum brazing alloys are used to provide an all-aluminum structure with excellent corrosion resistance and good strength and appearance. The melting point of the brazing filler metal is relatively close to that of the material being joined. However, the base metal should not be melted; as a … Read more

Arc Welding Aluminum: How to Stick Weld Aluminum

When arc welding aluminum with the shielded metal-arc welding (SMAW) process, a heavy dipped or extruded flux coated electrode is used with DC Reverse Polarity (DCRP). The electrodes are covered similarly to conventional steel electrodes. The flux coating provides a gaseous shield around the arc and molten aluminum puddle, and chemically combines and removes the aluminum oxide, … Read more
