MMET 207 - Aluminum Series

What are the properties of 1000 series aluminum?

-99% pure or higher in aluminum
-used in electrical and chemical fields
-excellent corrosion resistance
-high thermal and electrical conductivity
-low mechanical properties and excellent workability
-moderate increases in strength from strain hardening
-iron and silicon are major impurities

What are the characteristics of 2000 series aluminum?

-may require artificial aging
-do not have as food corrosion resistance as most other Al alloys
-often clad with 6000 series or pure Al
-2024 best known alloy

What are the properties of 3000 series aluminum?

-limited Mn addition - 1.5%
-3003 is general purpose alloy
-moderate strength
-good workability

What are the characteristics of 4000 series aluminum?

-Si lowers melting point without causing brittleness
-Used in welding wire and brazing alloys
-When diluted with heat treatable alloys in welding become moderately heat treatable
-Become dark gray when anodized
