Ingot of tantalum. Pig. Brand.

Ingot of tantalum. Pig. Brand.

Supplier — AvekGlob Company — offers tantalum ingots and pigs at affordable prices from the manufacturer. 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. Tantalum, long recognized for its excellent strength at high temperatures, is also one of the most corrosion-resistant metals with resistance to acid attack, comparable to resistance to glass and platinum. Due to these qualities — strength at high temperatures and excellent corrosion resistance, tantalum ingots and pigs are used in a wide range of laboratory and industrial applications.

Urgency of application

Tantalum ingots and ingots are used as an additive to solid alloys and nickel-based alloys, where the addition of this element induces and optimizes the desired hardening of the solid solution. Areas of application — products operating at high temperatures, subject to thermal, vibration and shock loads. Solid alloys that contain tantalum resist corrosion and oxidation and provide excellent surface stability. With a tantalum content of 3 to 10%, such alloys are used to improve assembly details for the aerospace industry, as well as turbine blades in aircraft engines and industrial gas turbines.

Chemical composition

The composition of HDTV tantalum used for the production of tantalum ingots and pigs as impurities includes the following elements (data — in percent)
