Available Grades and Materials

We offer Ta-1 and Ta-2 grades to meet your specific requirements. Both grades maintain 99.95% minimum purity with excellent chemical stability. The materials undergo vacuum annealing for optimal performance characteristics.

You can choose between alkaline wash surface or machined finish options. Custom compositions are available for specialized applications requiring unique properties.

Manufacturing Process

Our production begins with high-purity tantalum powder created through sodium thermal reduction. The powder undergoes cold isostatic pressing at pressures exceeding 200 MPa for superior density.

Sintering occurs in vacuum conditions greater than 10⁻² MPa at temperatures above 2400°C. This process creates ingots with 15.4 g/cm³ density and 99.99% purity. Rolling and heat treatment follow to achieve the final specifications.
