Custom-Welded Zirconium Crucible

Our Custom-Welded Zirconium Crucibles are precision-engineered vessels specifically fabricated for demanding industrial and research applications where off-the-shelf solutions fall short. Utilizing advanced welding techniques on high-grade zirconium alloys, we create durable, leak-tight crucibles tailored to your exact dimensional and performance specifications. These crucibles excel in highly corrosive environments and controlled atmospheres where material purity and structural integrity are paramount.

Key Features & Specifications
1. Primary Material: High-purity zirconium alloys (R60702, R60705, or as specified)

2. Manufacturing Process: Precision TIG (Tungsten Inert Gas) or electron beam welding

3. Key Property: Excellent ductility and weldability of zirconium allows for complex custom shapes

4. Typical Wall Thickness: 2 mm to 10 mm (customizable)

5. Standard Volume Range: 50 mL to 20 L (custom sizes available)

6. Surface Finish: Standard mill finish, electropolished, or pickled surface (optional)

7. Maximum Service Temperature: Up to 350°C in air; up to 800°C in vacuum/inert atmosphere

8. Pressure Rating: Designed for vacuum or low-pressure applications (specific ratings depend on design)

9. Leak Tightness: Helium leak tested upon request

Technical Advantages
1. Superior Corrosion Resistance
The welded seams maintain the exceptional corrosion resistance of the parent zirconium material, performing reliably in acidic, alkaline, and chloride-containing environments where stainless steel would fail.

2. Design Flexibility
From simple cylinders to complex geometries with integrated flanges, spouts, or mounting brackets, welding enables shapes that are impossible with standard machining or forging.

3. Material Integrity
Our controlled welding procedures and post-weld heat treatments minimize grain growth and preserve the mechanical properties of the zirconium alloy, ensuring long service life.

4. Cost-Effectiveness for Prototypes & Small Batches
Custom welding is often more economical than machining for one-off pieces or small production runs, providing a practical path for specialized equipment.

5. Target Applications
Chemical Process Industry: Liners, reaction vessels, or distillation components for handling aggressive chemicals like hot hydrochloric or sulfuric acid.

6. Semiconductor Manufacturing: Custom boats, holders, or chambers for high-purity processes.

7. Laboratory Research: Specialized vessels for unique experimental setups in materials science or chemistry.

8. Aerospace & Nuclear: Prototype components requiring zirconium's specific properties, tested in controlled environments.

Customization Process
Consultation: Share your application requirements, chemical environment, temperature, pressure, and preliminary sketches or CAD models.

Design & Quotation: Our engineers will analyze the design for manufacturability and provide a detailed quote, including material selection (e.g., zirconium alloy grade) and lead time.

Fabrication & Quality Assurance: Crucibles are manufactured and undergo rigorous inspection, including dimensional checks and visual/dye penetrant testing of all welds.

Delivery & Support: Products are safely packaged and shipped with full documentation. We provide guidance on proper handling and use.

Ordering Information & Notes
Please provide detailed drawings with all critical dimensions and tolerances.

Specify the required zirconium alloy grade, final surface finish, and any necessary certifications (e.g., material traceability).

Lead times vary based on design complexity. Contact us for an accurate estimate.

For current pricing, please inquire as costs depend on material dimensions, alloy selection, and the fluctuating zirconium price.
