Our Strength
More than 20 years’ experiences in tantalum /niobium and its alloy smelting and deep processing, we make sure that we can provide you with the best quality products with competitive price.
We have entered a long-term contract with the Chinese biggest tantalum/niobium hydrometallurgy smelter to assure our stable and high quality raw material. We don’t buy any sources so called conflict mineral. We only use tantalum and niobium raw materials from ethically trustworthy source is officially confirmed by EICC certificate.
The full and strict quality control system throughout the whole production line from the raw material till the products ready for delivery, we reject the unqualified products timely to make sure only qualified products can be received by our customers.
In addition, we offer various kinds of services to our customers such as OEM, forging services, sintering services, laser cutting services, rolling services, milling services, trade in services etc. Please feel free to send us the enquiries as long as you require services.
We have been verified by ISO 9001Quality Management System Authentication. We now owns core equipment such as domestic advanced EB furnace, high vacuum Annealing Furnace, plate and strip rolling mill, High precision surface grinding machine etc. Advanced equipment not only produces our fine quality products but also ensure us provides the processing services such as smelting, forging services, sintering services, laser cutting services, rolling services, milling services etc.
