Tantalum Sheet

Tantalum Sheet

Description

Tantalum sheet, also known as tantalum plate, has good machining property in far below room temperature. You can easily machine the tantalum sheet to your specific requirements by punching, cutting, deep drawing or pressing. Tantalum sheet also shows excellent corrosion resistance. Acid can not harm it.

Application

Tantalum sheet is used in chemical process equipment, cathodic protection systems for steel structures such as bridges, water tanks, prosthetic devices for humans such as hips, plates in the skull, suture clips, corrosion resistant fasteners, screws, nuts, bolts, high temperature furnace parts and high temperature alloys (Ta10W alloy) for air and land based turbines (e.g. jet engines).
