FAQ
What makes ceramic sealing alloys different from standard alloys?
Ceramic sealing alloys are specifically formulated to maintain dimensional stability and mechanical properties at high temperatures while forming hermetic seals with ceramic components. They typically contain controlled amounts of elements like yttrium, hafnium, or aluminum that form protective oxide layers during service.
How does Qingchuan ensure material purity in its products?
The company employs multiple purification stages including vacuum melting, electroslag remelting (ESR), and vacuum arc remelting (VAR). Each production batch undergoes ICP-MS analysis to verify that impurity levels remain below 50 ppm for critical elements, with some products achieving 99.999% purity.
What is the typical lead time for custom alloy development?
Development timelines vary based on complexity but generally range from 8-16 weeks. This includes composition optimization, prototype production, and testing phases. The company maintains stock of common base alloys to expedite customization projects.
