Tinplate is also called tin-plated steel, which is made by plating tin on a thin steel substrate. The base material of thin steel plate is made of low-carbon steel, and its thickness is generally 0.1 to 0.4 mm.
Tinplate: Zn, Fe alloy (Zn is coating)
Tinplate is the common name for electroplated tin sheet steel. The English abbreviation is SPTE, which refers to cold-rolled low-carbon thin steel sheet or steel strip plated with commercial pure tin on both sides, also called tin-plated iron. Tin mainly plays a role in preventing corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin in a single material. It has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility.
In an acidic environment, the tin protective layer of tinplate is in direct contact with the outside world, and the tin is corroded very slowly, which protects the substrate. If there are defects such as pinholes and cracks on the tin protection layer, part of the substrate will be exposed, causing the substrate to be quickly corroded.
Tinplate is an iron sheet with a layer of tin plated on the surface, it is not easy to rust, also called tin plated iron. Tinplate was first produced in Bohemia (in today's Czech Republic and Slovakia). The area has been rich in metal since ancient times, with advanced technology and know how to use water power to engage in machine manufacturing. Tinplate has been produced since the 14th century. For a long period of time, this place has been the main producing area of tinplate in the world. At that time, tinplate was mainly used to make tableware and drinking utensils.
The origin of the name of tinplate
Tinplate was called TinPlate in the early days, and its official name should be tin-plated steel sheet. Because China's first batch of foreign iron was imported from Macau in the middle of the Qing Dynasty, Macau was transliterated "horse mouth" at that time, so the Chinese generally called it "tinplate."
Tinplate originated in Bohemia (in today's Czech Republic and Slovakia). The area has been rich in advanced metal technology since ancient times, and knows how to use water power to engage in machine manufacturing. Tinplate has been produced since the 14th century. For a long period of time, this place has always been the main producing area of tinplate in the world. At that time, tinplate was mainly used to make tableware and drinking utensils.
In the 17th century, Britain, France, and Sweden all hoped to establish their own tinplate industries, but due to the need for large amounts of funds, they have not been developed for a long time. It was not until 1811 that Brian Donkin and John Hall started tinplate canned food that tinplate manufacturing developed on a large scale. Today, the world produces about 250,000 tons of tin annually, and more than one-third is used to make tinplate, most of which is used in the canned food industry.
