❓ Frequently Asked Questions
Q
What does the R05200 grade mean for pure tantalum tubes?
R05200 is the American Standard (ASTM) designation for commercially pure tantalum. It specifies that the tantalum content must be ≥ 99.95%, with strictly controlled trace impurity levels. This grade is widely used in corrosion-resistant equipment, chemical processing, and high-temperature applications where material purity is critical.
Q
Can the dimensions of the tantalum tubes be customized?
Yes. Yunjie offers full dimension customization including outer diameter (OD), inner diameter (ID), wall thickness, and length. Additional processing services such as cutting, bending, welding, flaring, and necking are also available to meet specific application requirements.
Q
What is the difference between Soft State (M) and Hard State (Y) delivery conditions?
Soft State (M) refers to tubes that have been annealed after processing, resulting in improved ductility, formability, and ease of further fabrication. Hard State (Y) refers to tubes in a cold-worked condition, offering higher tensile strength and hardness, suitable for applications that require greater mechanical performance.
Q
What surface conditions are available, and how do I choose the right one?
Four surface conditions are available: Pickled Surface (clean oxide-free finish), Bright Annealed Surface (smooth, reflective, suitable for high-purity environments), Cold-Rolled As-Rolled Surface (economical, standard finish), and Polished Surface (highest aesthetic and cleanliness standard). The choice depends on your application's cleanliness, corrosion, and appearance requirements.
Q
What is the minimum order quantity, and are there discounts for large orders?
The minimum order quantity is 1 kg, calculated based on actual order weight. For thin-walled tubes, ordering by the piece is also supported for small-batch needs. Bulk purchase orders are eligible for preferential pricing policies — please contact our sales team for a customized quotation.
Q
In which industries are pure tantalum tubes commonly used?
Pure tantalum tubes are widely used in chemical processing (heat exchangers, reactors, pipelines), pharmaceutical manufacturing, semiconductor fabrication, aerospace components, medical implants, and high-temperature furnace equipment — any application requiring extreme corrosion resistance, high-temperature stability, and material purity.
