Zirconium crucible price manufacturers

When sourcing zirconium crucibles, the price is primarily driven by material purity (typically 99.5% to 99.9%) and the manufacturing process (machined vs. deep-drawn). Buyers should verify the Zirconium grade (e.g., R60702), as this determines corrosion resistance in extreme environments. Additionally, wall thickness and dimensions significantly impact the raw material weight, which is a core component of the final quote.

Zirconium crucibles are essential for sodium peroxide fusions and handling highly alkaline fluxes. Unlike platinum, they offer a cost-effective alternative for high-temperature applications up to 550°C to 600°C in oxidizing atmospheres. Buyers must ensure the crucible is compatible with their specific acid or base concentrations to avoid premature failure, which increases the long-term Total Cost of Ownership (TCO).

Ensure the supplier adheres to ASTM B551 specifications for zirconium and zirconium alloy strip, sheet, and plate. It is critical to request a Material Test Report (MTR) and Certificate of Analysis (COA) to confirm the absence of impurities like Hafnium if nuclear-grade purity is required. For international trade, verify that the manufacturer holds ISO 9001:2015 certification to ensure process consistency.

To optimize costs, buyers should look for tiered pricing models where the unit price drops significantly at quantities of 10, 50, or 100 pieces. Since zirconium is a specialty metal, price volatility in the raw material market is common; securing a fixed-price contract for a 6-month supply can mitigate budget risks. Furthermore, choosing standardized sizes rather than custom molds can reduce lead times and tooling charges.

The primary risks include material substitution (using lower-grade alloys) and shipping damage due to the brittle nature of oxidized layers. To mitigate this, use Trade Fulfillment services on Made-in-China.com to ensure payment is only released upon confirmation of quality. Always insist on vacuum packaging or moisture-proof wrapping to prevent surface oxidation during long-term sea freight.

Negotiate for a sample-first policy where the cost of the sample is deducted from the first bulk order. Demand third-party inspection (such as SGS or Intertek) before the final balance payment is made. Clearly define tolerances (+/- 0.1mm) and surface finish requirements in the Proforma Invoice (PI) to have legal recourse in case of disputes.

Zirconium products may be subject to dual-use export controls depending on the purity and country of origin. Buyers should confirm the HS Code (typically 8109.90) and check for any anti-dumping duties or specific import permits required by their local customs. For shipping to the US or EU, ensure the supplier provides a Commercial Invoice that accurately reflects the metal weight and purity to avoid customs delays.
