Tantalum Bar & Tantalum Rod Description

Tantalum bar and tantalum rod are made of tantalum ingots. Tantalum bars and rods can be used in the chemical industry and oil industries due to their corrosion resistance. SAM is a trusted supplier of tantalum rods & bars and we can provide customized tantalum products. SAM’s tantalum rod is worked cold from ingot to final diameter. Forging, rolling, swaging, and drawing are used singularly or in combination to reach the desired size.
Ta rods and Ta bars are mainly used as high-temperature alloys containing tantalum, tantalum-based heat-resistant, and corrosion-resistant alloy additives.
