Niobium and Tin – About Elements


Niobium is a soft, grey, ductile transition metal, often found in the minerals pyrochlore (the main commercial source for niobium) and columbite.


Tin is a post-transition metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide. The first alloy used on a large scale was bronze, made of tin and copper, from as early as 3000 BC.

Niobium and Tin – Applications


Niobium consumption is dominated by its use as additive to high strength low alloy steel and stainless steel for oil and gas pipelines, car and truck bodies, architectural requirements, tool steels, ships hulls, railroad tracks. However, there are a number of other applications for niobium metal and its compounds. Although niobium has many applications the majority is used in the production of high-grade structural steel. The second largest application for niobium is in nickel-based superalloys. Niobium-tin alloys are used as superconducting magnets.


The largest single application of tin is in the manufacture of tinplate (steel sheet coated with tin), which accounts for approximately 40% of total world tin consumption. Tin bonds readily to iron and steel to prevent corrosion. Tin-plated steel containers are widely used for food preservation, and this forms a large part of the market for metallic tin. Tinning is the process of thinly coating sheets of wrought iron or steel with tin, and the resulting product is known as tinplate. The term is also widely used for the different process of coating a metal with solder before soldering. There are two processes for the tinning of the black plates: hot-dipping and electroplating.
