description
Titanium alloy castings provide titanium's exceptional strength-to-weight ratio and corrosion resistance in complex shapes - titanium is 40% lighter than steel with comparable strength, and resists corrosion in seawater and chlorides that quickly degrade most other metals. The casting process produces near-net-shape parts at a lower cost than forging or CNC machining. Ti-6Al-4V is the workhorse titanium alloy - used in aerospace airframes, engine components, and medical implants. The ELI (extra low interstitial) variant has better fracture toughness for critical applications. Ti-5Al-5V-5Mo-3Cr (Ti-5553) is a newer beta titanium alloy with higher strength potential for aerospace applications.
Why Titanium Castings Are Expensive
Titanium melts at 1668°C - above the melting point of most steel alloys and far above what most foundries can handle. The crucible and mold materials that survive that temperature are expensive, and titanium's reactivity at high temperature means the melt must be protected from atmospheric contamination. This is why titanium castings cost significantly more than steel or aluminum castings of similar size.
FAQ
Q1: MOQ?
A1: 10 pieces for titanium castings.
Q2: Materials?
A2: Ti-6Al-4V (standard), Ti-6Al-4V ELI (medical/aerospace), Ti-5553 (high strength).
Q3: Casting method?
A3: Investment casting - cold chamber for most alloys, hot chamber for some beta alloys.
Q4: Surface finish?
A4: As-cast (standard), machined (critical surfaces), shot peened (fatigue enhancement).
Q5: Tolerances?
A5: Investment casting provides good dimensional accuracy - ±0.1 mm typical.
Q6: Custom configurations?
A6: Yes. Custom geometries, material substitutions, post-cast heat treatments.
