Frequently Asked Questions
Find essential information regarding our material sourcing, international standards, and custom supply capabilities.
A: We primarily provide Titanium, Tantalum, Zirconium, and Niobium. These are essential for industries requiring extreme corrosion resistance and thermal stability, such as chemical processing, aerospace, medical, and power generation.
A: Yes, all materials supplied by ATX are manufactured and tested in accordance with global standards including ASTM, ASME, AMS, and ISO. We provide Mill Test Certificates (MTC) to guarantee full traceability and quality.
A: Absolutely. In addition to standard stock, we specialize in supplying custom dimensions and ultra-thin foils. Please contact our sales team with your specific requirements for a customized quote.
A: While both offer excellent corrosion resistance, Titanium is known for its high strength-to-weight ratio, whereas Tantalum offers superior resistance to highly concentrated acids (like sulfuric acid) at high temperatures where most other metals fail.
A: We partner with world-class mills and perform rigorous internal inspections, including chemical analysis and mechanical property testing. Our quality control system ensures that every material meets the high-purity standards required for critical industrial applications.
