Each tungsten crucible is meticulously packaged to ensure maximum protection during transport and storage. We use sturdy wooden crates for larger crucibles and robust cartons for smaller sets, ensuring that each item is securely immobilized and protected from any potential damage.
Q1: Why choose tungsten for crucibles?
A1: Tungsten’s high melting point and low thermal expansion rate make it ideal for maintaining integrity under extreme conditions.
Q2: Can I customize the dimensions of a tungsten crucible?
A2: Yes, we offer customization for both dimensions and shapes to suit your specific requirements.
Q3: What are the purity levels available for these crucibles?
A3: Our standard purity is ≥99.95%, but we can provide up to 99.999% purity for specialized applications.
Q4: How are tungsten crucibles packaged?
A4: Each crucible is securely packaged in a wooden crate to protect it during transportation. Smaller sets may be packaged in cartons.
Q5: How should I handle and maintain my tungsten crucible?
A5: To ensure longevity, avoid rapid temperature changes and mechanical shocks during use.
