Steel Types
- Stainless Steel - alloy contains P 12% chromium
- Weathering Steel - high strength, low alloy steel that forms an oxide coating
- Tungsten Steel - alloy containing 10%- 20% tungsten for increase hardness
-
Nonferrous Metals - Aluminum
- Aluminum - ductile, corrosion resistant due to oxide film
- Anodizing - process of thickening and tinting oxide film
- Easily extruded
- Need to isolate from other metals to prevent galanic action
-
Glavanic Series
- Least reactive - gold, platinum
- Most reactive - aluminum, zinc, magnesium
-
Nonferruous Metals - Copper/Brass
- Copper - ductile, corrosion resistant due to oxide film
- Easily Extruded, need to isolate from other metals to prevent galvanic action
- Brass - copper alloy containing zinc
-
Nonferrous Metals - Lead
Soft, malleable, corrosion resistant
