Frequently Asked Questions
Q
What nickel grades are available for Yunjie nickel crucibles?
Yunjie nickel crucibles are available in multiple grades including N4, N6, N8, N5 (equivalent to N02200), and N7 (equivalent to N02201). Each grade meets its corresponding industry standard, with Ni+Co content of ≥99%, ensuring high purity and reliable performance.
Q
What manufacturing process is used to produce these nickel crucibles?
The crucibles are produced using either Stamping Forming or Spinning Forming, followed by Vacuum Annealing to relieve internal stress and improve ductility, and then Precision Polishing to achieve a high-quality surface finish. This multi-step process ensures consistent dimensional accuracy and superior mechanical properties.
Q
Can the nickel crucibles be customized in size or shape?
Yes. Yunjie offers comprehensive customization services including custom sizes, edge curling, bottom thickening, drilling, and welding brackets. In addition to standard cylindrical, conical, and square shapes, special-shaped crucibles can be manufactured according to customer-provided drawings or requirements.
Q
What surface finishes are available for nickel crucibles?
Three surface finish options are available: Annealed Bright Surface, which offers a clean and smooth appearance after heat treatment; Precision Polished Surface, providing a mirror-like finish for applications requiring low contamination; and Passivated Surface, which enhances corrosion resistance for demanding chemical environments.
Q
What is the minimum order quantity for nickel crucibles?
The minimum order quantity is just 1 piece, making Yunjie nickel crucibles accessible for laboratory use, research institutions, and small-scale industrial applications, as well as large volume industrial orders.
Q
What are the key advantages of using nickel crucibles over other materials?
Nickel crucibles offer a unique combination of properties that make them ideal for high-demand applications: excellent high-temperature resistance, strong corrosion resistance against alkalis and many acids, uniform thermal conductivity for consistent heating, high mechanical strength, good impact resistance, and a high surface finish. These properties together result in a long service life and reduced replacement costs.
