Circle, rod tantalum

Circle, rod tantalum

Supplier — AvecGlob Company — offers at a reasonable price from the manufacturer a circle and a bar 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 bulk rolled metal from tantalum are ingots. Then, the metal is cold rolled 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 rod and the circle, responsible parts of the pipelines (valves, valves, etc.), which operate at elevated temperatures, are produced.

Typical parts made from tantalum are also corrosion resistant elements of laboratory equipment and control technology of furnaces for electron beam melting. In metal working, solid alloys are used, including tantalum. By its chemical inertness, tantalum rolling is able to effectively replace similar products, which are produced from platinum. The bar and circle of tantalum are also used as a material for bioimplants.

Chemical composition

Depending on the type of rolled metal, the following elements are included in the composition of tantalum billets (numerical data — in percent, tantalum — the rest)

Assortment and application features

At a temperature of less than 150 ° C, tantalum rolling has an increased viscosity and is difficult to process on machine tools.
