Casting Alloys | 4xx.x - Al-Si Alloys
- Non-heat treatable/sand,permanent mold,and die castings
- Excellent fluidity/good for intricate castings
- Typewriter frames/dental equipment/marine/architectural
- Representative alloys:413.0,443.0
- Approximate ultimate tensile strength range:17-25 ksi
It combines moderate strength with high elongation before rupture and good corrosion resistance. The alloy is particularly suitable for intricate, thin walled, leak-proof, fatigue resistant castings.
