Al-Cu-Mg-Ag Alloys

Al-Cu-Mg-Ag alloys represent a breakthrough in high-strength aluminum metallurgy, featuring superior performance characteristics for aerospace applications. These advanced aluminum alloys incorporate a high copper-to-magnesium ratio with strategic silver additions, creating exceptional strength properties at elevated temperatures up to 250°C.

Al-Fe Conductor Alloys: Part One

Aluminum alloys with 0.5-0.9% Fe content have largely supplanted 1350 EC alloy for building electrical circuits because the latter frequently suffered from gradual loosening at terminals, which gave rise to overheating. This problem has been completely overcome in the new conductor alloys without sacrifice of conductivity.

Al-Fe Conductor Alloys: Part Two

Although in the past it was common practice to fully anneal the rod before wire drawing, continuous processing is now usually practiced, that is the as-worked rod with retained substructure goes directly to the cold forming. Drawing of the rod through 12 dies with 20% reduction per die brings the total true strain to 6.89.

AlMg Alloys: Part One

AlMg alloys have a wide range of advantageous characteristics which means they can be used in many different applications, with many being in extreme temperatures or other aggressive environments.
A prime example of such materials can be seen in the 5xxx series of alloys which display excellent corrosion resistance in combination with very good mechanical properties to cope in the harshest conditions such as marine environments.

AlMg Alloys: Part Two

In recent times there has been an ever increasing need for lightweight materials with increased strength to help meet tighter deadlines relating to cost savings.
Al-Mg alloys can offer excellent solutions for these requirements by exhibiting favorable formability, high strength and high strain hardening ability offering not only strong finished product but stable.

AlMgSi Alloys: Advanced Aluminum Alloys for Automotive Applications

AlMgSi alloys represent a critical class of aluminum alloys driving lightweight automotive design through their exceptional combination of strength, castability, and corrosion resistance. These aluminum-magnesium-silicon alloys have gained prominence in the automotive industry as viable substitutes for heavier metals, contributing to reduced fuel consumption and CO₂ emissions.
