Tantalum sheet
Supplier — the company AvecGlob — offers at affordable prices from the manufacturer a sheet of tantalum. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Technical specifications
Tantalum is silver metal, with a characteristic luster, which is distinguished by high corrosion resistance. Initial ingots for the production of sheet metal from tantalum are ingots. Further, the metal is cold rolled to the required thickness and then, if necessary, mechanical or plastic treatment.
Urgency of application
High corrosion resistance of tantalum causes its primary use in the petrochemical, chemical and gas industries. From the tantalum sheet, responsible hull structures are produced, designed for operation at high temperatures, and in corrosive environments (gases, heated acids, etc.).
Typical parts made from tantalum are corrosion resistant elements of laboratory equipment and control technology of furnaces for electron beam melting. In metal working, solid alloys are used, including tantalum. Due to its chemical inertness, tantalum sheets can effectively replace similar products, which are produced from platinum. Tantalum sheets are also used as a starting material for bioimplants, since they do not cause rejection by the human body.

Assortment and application features
At a temperature of less than 150 ° C, tantalum sheet has an increased viscosity and is difficult to process on machine tools (in particular, it is advisable to provide a punching instead of drilling).
