- Medium Carbon Steels (e.g., 1045, 4140): Higher strength and hardness; ideal for high-strength components
- Free-Machining Steels (e.g., 1215, 12L14): Excellent machinability for high-volume production
Stainless Steels
Learn More Stainless Steels
- Austenitic Stainless Steels (e.g., 303, 304, 316, 304L): Excellent corrosion resistance and weldability
- Martensitic Stainless Steels (eg., 440C): High hardness and wear resistance; suitable for cutting tools, bearings, and valve components
- Precipitation Hardening Stainless Steels (e.g., 17-4 PH): High strength, hardness, and corrosion resistance; used in aerospace and demanding industrial applications
Aluminum Alloys
Learn More Aluminum Alloys
- 6000 Series Aluminum Alloys (e.g., 6061-T6, 6063-T6): Good balance of weldability, corrosion resistance, and medium strength
- 7000 Series Aluminum Alloys (e.g., 7075-T6): High strength and fatigue resistance; ideal for aerospace and high-performance applications
Other Alloys
- Brass (e.g., C360 Brass): Excellent machinability, good corrosion resistance, and attractive appearance
