Description

Tantalum is a sensible choice whenever high corrosion resistance is required. Even though tantalum is not one of the noble metals, it is comparable to them in terms of chemical resistance. In addition, tantalum is very easy to work at well below room temperature despite its body-centered cubic crystal structure.

This material data has been provided by Plansee.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
