Unlock Unmatched Performance in Extreme Environments
In industries where temperatures soar beyond 2000°C and purity is non-negotiable, standard materials fail. Tungsten crucibles stand as the undisputed champion, engineered to deliver unparalleled reliability and performance where others falter. Crafted from the highest purity tungsten (W≥99.95%), our crucibles leverage advanced spinning crucible tungsten technology to create a superior product for your most critical processes.
Why Tungsten? Unrivaled Material Properties
Tungsten possesses the highest melting point of all metals (3422°C), exceptional high-temperature strength, outstanding creep resistance, and minimal vapor pressure. This unique combination makes it the only viable choice for numerous ultra-high-temperature applications demanding extreme thermal stability and chemical inertness.
The Spinning Crucible Advantage: Superiority Forged in Process
Unlike traditional sintered or machined tungsten crucibles, our tungsten spinning crucible is manufactured using a specialized metal spinning technique. This advanced process delivers critical benefits:
1. Enhanced Grain Structure & Density: Spinning aligns the tungsten grain structure parallel to the crucible wall, significantly increasing density (near theoretical) and eliminating porosity common in sintered products. This translates to superior resistance to penetration by molten materials and reduced gas permeability.
2. Exceptional Mechanical Strength: The refined grain structure and work hardening during spinning result in dramatically improved mechanical strength, fracture toughness, and resistance to thermal shock – crucial for repeated heating and cooling cycles.
3. Improved Thermal Conductivity: Optimized grain flow enhances thermal conductivity radially, promoting more uniform heating and cooling profiles within your furnace or process.
4. Superior Surface Finish: The spinning process yields a smoother internal surface finish compared to sintered alternatives, minimizing sticking and contamination of sensitive melts like sapphire crystals or high-purity metals.
5. Cost-Effectiveness: Spinning allows for the production of near-net-shape crucibles with minimal material waste, offering excellent value for such a high-performance component.
Key Applications Demanding Tungsten Spinning Crucibles
1. Sapphire Crystal Growth (Kyropoulos, Czochralski): The ultimate choice for melting highly reactive alumina (Al2O3) due to its purity, non-reactivity, and ability to withstand corrosive conditions at extreme temperatures without contaminating the crystal.
2. Rare Earth Metal Refining & Melting: Essential for processing reactive and high-purity rare earth elements (e.g., Yttrium, Scandium, Lanthanum) and their alloys where contamination must be avoided.
3. High-Purity Metal Evaporation (E-Beam, Thermal): Used as evaporation boats or liners within larger sources (tungsten crucible liner) for depositing ultra-pure thin films in semiconductors and optics.
4. Quartz Glass Refining & Processing: Handling molten quartz glass where purity and resistance to silicon vapor are critical.
5. Research & Development: Ideal for experimental processes involving ultra-high temperatures and reactive materials where reliable containment is paramount.

Critical Precautions for Maximizing Tungsten Spinning Crucible Life
To ensure optimal performance and longevity of your investment:
1. Controlled Atmosphere is Key: Always operate in a high-purity inert atmosphere (Argon, Nitrogen) or high vacuum. Exposure to oxygen at high temperatures will rapidly oxidize and destroy the crucible.
2. Avoid Thermal Shock: Implement controlled heating and cooling ramps. Never introduce cold material into a hot crucible or quench a hot crucible. Rapid temperature changes can cause cracking.
3. Prevent Chemical Contamination: Carefully select charge materials. Avoid alkaline earth metals, oxides, nitrates, and other compounds that can form low-melting-point eutectics with tungsten, leading to catastrophic failure.
4. Proper Handling: Tungsten is brittle at room temperature. Handle crucibles with extreme care using clean gloves to avoid contamination and prevent mechanical damage (chipping, cracking).
5. Compatible Fixtures: Ensure furnace supports and lifting tools are made from compatible refractory metals (e.g., Molybdenum) and do not cause localized stress points.

At first we will make sure that we got all customer's requirements clear. Then place order to production department and inspection department. Each production process will test themselves if everything is right. And before shipping, all products will pass the packing department only after inspection department inspected that the products meet customer's requirements. If not, the products will go back to production department for fixing or remaking.
For production, normally our lead time is 20-30 days. But according to different products and different quantity, it changes a little. If your order is emergency, contact with us, we will find a way out to solve your problem. For shipping, normally we ship by express and air. Express takes about 7-10 days, and air 3-5 days. And if customer requires by sea, we will ship by sea, it takes normally 40-50 days.
All our products are shipped after strict inspection and safety packing. Inspection by each production process makes sure the quality is good. And the inspection department will inspect again carefully to make sure everything is right. But if quality issue really occurs, we are sorry, and we will be responsible. To fix the products or remake them, we will make everything right.
In order to keep our healthy cooperation, our payment term normally is 50% payment in advance, balance paid before shipping. And if customer needs, we will calculate the shipping cost for your reference.
