Packaging of tantalum
Our tantalum rod is tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage to tantalum and its alloy which might be caused during storage or transportation. The outer package is usually a wooden crate.
We can also provide tantalum alloy rods and other customized parts, please send us your request to sales@edgetechmat.com for any needs on tantalum products.
