Scandium Metal (Element Symbol: Sc; CAS No.: 7440-20-2; EINECS NO.: 231-129-2) is a premium soft, silver-white transition metal renowned for its exceptional chemical activity and versatile performance. With a molecular weight of 44.95, density of 2.99g/cm³, melting point of 1539°C, and boiling point of 2836°C, this metal stands out for its stability under extreme conditions while maintaining reactivity with hot water to generate hydrogen gas. Available in silver-white ingots, lumps, or customized sizes, our scandium metal boasts industry-leading purity levels ranging from 99.9% (3N) to 99.9999% (6N), meeting the stringent requirements of diverse high-tech and industrial applications. As a trusted high purity scandium metal manufacturer, we prioritize precision and consistency, ensuring each batch adheres to strict quality standards for rare earth and non-rare earth impurities.
Exceptional Purity Grades: Our scandium metal offers multiple purity options, including 4N (99.99%), 4N5 (99.995%), 5N (99.999%), and 6N (99.9999%). Each grade maintains a minimum REM content of 99%, with rare earth impurities as low as 0.0001% (6N grade) and non-rare earth impurities (Si, Fe, Ca, Al, etc.) strictly controlled to ultra-low levels.
Superior Physical & Chemical Properties: The soft, silver-white scandium metal combines high thermal stability (resisting temperatures up to 2836°C) with active chemical reactivity, making it adaptable to both reactive and stable operational environments.
Customizable Forms: Beyond standard ingots and lumps, we provide precision laser scandium metal and customized sizes to fit specialized manufacturing processes, such as vapor deposition for electronic components.
Enhanced Performance: High purity ensures optimal functionality in critical applications, from improving alloy strength to boosting photoelectric conversion efficiency.
Cost-Effective Reliability: Strict impurity control reduces downtime and maintenance costs in industrial processes, while versatile forms eliminate the need for secondary processing.
Sustainable Application: As an energy-efficient material, it supports green technologies like solar cells and energy-saving lighting, aligning with global sustainability goals.

Alloy Material: Adding scandium metal to alloys (e.g., aluminum-scandium alloys) significantly enhances strength, corrosion resistance, and heat resistance. This makes the alloys ideal for aerospace components, high-performance automotive parts, and structural materials requiring durability under extreme stress.
Catalyst: Scandium compounds serve as high-efficiency catalysts in chemical synthesis, enabling faster reactions, higher yields, and reduced energy consumption in pharmaceutical and petrochemical industries.
Special Glass Production: High strength scandium metal is a key additive in manufacturing special glass with unique optical, thermal, and mechanical properties, suitable for scientific research equipment, aerospace windows, and precision optical instruments.
Electric Light Source Material: The star application of scandium metal lies in manufacturing scandium sodium lamps—lighting fixtures celebrated for high luminous efficiency, natural light color, energy savings, long service life (up to 10,000 hours), and strong fog-breaking ability. They are widely used in highways, stadiums, and industrial workshops.
Solar Cells: Integrating scandium metal into solar cell panels enhances light absorption capacity, increasing photoelectric conversion efficiency by up to 15%. This advancement drives the performance of renewable energy systems for residential, commercial, and utility-scale projects.
Electronic Devices: Vapor deposition scandium metal and high-purity grades are essential for semiconductor devices, ferrites, and computer magnetic cores. Their excellent conductivity and magnetic properties ensure stable performance in modern electronics, from smartphones to industrial control systems.
We provide four primary purity grades: 4N (99.99%), 4N5 (99.995%), 5N (99.999%), and 6N (99.9999%). Each grade is tested for rare earth and non-rare earth impurities, with detailed specifications available upon request. For custom purity requirements, our R&D team can develop tailored solutions.
To preserve its quality, scandium metal is sealed in vacuum packaging with moisture-proof materials, then placed in sturdy containers to prevent physical damage during transit. We comply with international shipping regulations for hazardous materials, ensuring safe and timely delivery worldwide.
Absolutely. With a melting point of 1539°C and boiling point of 2836°C, high purity scandium metal maintains structural integrity in high-temperature environments, making it suitable for aerospace engines, industrial furnaces, and thermal processing equipment.
Scandium sodium lamps, crafted with scandium metal, offer 30-50% higher luminous efficiency than traditional sodium lamps, consume less energy, and provide better color rendering (closer to natural light). Their strong fog penetration also makes them ideal for outdoor lighting in harsh weather conditions.
