FAQ
Q1: How do I choose between Gr5 and pure titanium crucibles?
Pure titanium: ≤400°C, mild corrosion, low cost
Gr5: 500–550°C, high strength, superior corrosion resistance, long service life, suitable for vacuum and precision applications
Q2: Can it be used continuously at 550°C in air?
Yes, the surface oxide film is stable; it will not peel off or contaminate the melt.
Q3: Is it suitable for vacuum melting of precious metals?
Fully compatible; non-magnetic, low-impurity, non-carburizing, and non-contaminating.
Q4: Can it be customized with a spout or lid?
Yes, all structures can be customized according to drawings.
