One of the countries active in the export of tin ingots is Indonesia, which extracts tin ingots known as Indonesian tin from its mines and supplies them worldwide. In this article from Asia Steel, we have taken a look at tin ingots, especially Indonesian tin ingots. Tin ingots are one of the most important metals used in lead-related industries. It is used in the production of pellets, batteries, gasoline, printing industry, pipes, various alloys, solders, color TVs, paint industries, glass, chemicals and X-ray protection items.
About tin ingots
In terms of quality, tin is classified into different classes, including electrolytic tin (99.95-99.98%), hard tin (99.6%) and technical tin (99%). Soldering materials using tin ingots are also classified into antimony solder, silver solder and soft solder.
Properties of tin
Tin is a metal that has flexibility and ductility and can be easily converted into wire and sheet. Although it is flexible at room temperature, it becomes brittle when heated.
The tinning process is applied as follows. The copper material to be tinned is first welded. The material is then plastered using salt. Then the resulting pieces are cleaned with fine sand. Next, the starch (ammonia salt) is rubbed into a container placed on the fire.
In the last process, the tin placed in the container is melted and tinned with cotton. Thanks to this step, tin-plated metal surfaces no longer oxidize.
In recent years, copper vases have been replaced by steel, aluminum and Teflon vases, and copper materials are used only for souvenirs, hotels and historic restaurants.
As copper pots dwindled, tin-plating became endangered. Tinning, a career that’s golden age from the 1950s to the 2000s, became one of the businesses that surrendered to technology.
However, it should not be forgotten that tin is a metal that is not toxic even in high amounts. Plain tin compounds and salts are slightly toxic. But on the other hand, some organic tin compounds are very toxic.
Which countries have tin ore reserves?
There are economically exploitable tin shale reserves in Malaysia, Bolivia, Thailand, Indonesia, Nigeria, Congo, Australia and China. The total tin reserves in the world are estimated at 5 million tons. China has the largest tin reserves in the world at 1.5 million tons. The annual production of tin in the world is approximately 250,000 tons.
Until the 19th century, tin was the main use of pottery and urban handicrafts. But in the present age, this material can be used in the field of modern soldering as well as in food storage containers and even in medicine. One of the uses of tin from ancient times until now is to use tin and combine it with copper to make bronze.
Indonesian tin ingots
It is the largest producer and exporter of tin ingots in the world after China. More than 90% of Indonesian tin ingots come from Banka and Blitung.
The annual consumption of tin in the world is about 300,000 tons, most of which is Indonesian tin. About 35% of these are used for soldering, about 30% for chemicals and pigments. By switching from lead-tin solder to lead-free solder with 95% tin content, annual demand has increased by approximately 10%.
Global market prices have also risen steadily in recent years. In 2003, the LME (London Metal Exchange) still paid around $ 5,000 per tonne, but by May 2008 that figure had risen to more than $ 24,000 per tonne. The largest consumers of Indonesian tin in the world are China, the United States, Japan, Germany, other European countries, Korea, Taiwan, Britain and France.
