Study Notes
Metal Alloys
- Brass: An alloy composed of copper and zinc.
- Bronze: An alloy made of copper and tin.
- Superalloys: Primarily based on nickel, designed for high-performance applications.
Metal Types
- Nonferrous Metals: Include copper, magnesium, and titanium; do not contain iron.
- Ferrous vs Nonferrous: Main distinction lies in iron content; ferrous materials contain iron, while nonferrous do not.
UNS Designations
- Cast Iron: Identified by the UNS prefix 'F' which categorizes its classification.
Applications of Metals
- Aluminum: Commonly used in aircraft support braces due to its lightweight nature.
- Cast Iron: Often utilized as a base for machinery, providing strength and durability.
- Tool Steel: Employed in punches and dies due to its hardness and wear resistance.
- Cold Rolled Steel (CRS): Used in car suspension parts, known for its finish and strength.
- Martensitic Stainless Steels: Typically found in knife blades due to their hardness.
- Austenitic Stainless Steels: Widely used in food conveyor parts due to corrosion resistance.
- Wrought Iron: Commonly used in the making of handrails, appreciated for its malleability.
- Bronze Components: Frequently found in axle bushings, offering good wear resistance.
- Titanium: Applied in medical devices, notably knee and hip joints due to its strength and biocompatibility.
- Superalloys: Critical for components in jet engines, designed to withstand extreme temperatures.
Carbon Content and Classification
- Carbon in Steel: Alterations in steel by bombardment of elements classify them as alloy steels.
- Cast Iron: Defined as material containing carbon in excess of 1.7% to 4.5%.
- AISI4135 Steel: Has a carbon content of 0.35%, indicating its specific alloy composition.
