Tin plate, also known as tinplate, is made by plating tin on a thin steel substrate. The base material of thin steel plate is made of low-carbon steel, with a thickness generally ranging from 0.1 to 0.4mm. Tin plate: Zn, Fe alloy (Zn is the coating) Tin plate is a common name for electroplated tin thin steel plate, abbreviated as SPTE, which refers to cold-rolled low-carbon steel plate or strip coated with commercial pure tin on both sides, also known as tinned iron. Tin mainly plays a role in preventing corrosion and rusting. It combines the strength and formability of steel with the corrosion resistance, solderability, and aesthetic appearance of tin in a single material, with the characteristics of corrosion resistance, non toxicity, high strength, and good ductility. In acidic environments, the tin protective layer of tinplate comes into direct contact with the outside world, providing protection to the substrate due to the slow corrosion rate of tin. If there are defects such as pinholes and cracks on the tin protective layer, some of the substrate will be exposed, leading to rapid corrosion of the substrate. Tin plate is an iron sheet coated with a layer of tin on the surface, which is not easy to rust, also known as tinned iron. Tinplate was born prematurely in Bohemia (now within the Czech Republic and Slovakia). The area has been rich in metal production since ancient times, with advanced technology and knowledge of using hydraulic power for machine manufacturing. The production of tinplate has been ongoing since the 14th century. For a long time, this place has been the main producer of tinplate in the world. At that time, tinplate was mainly used to make tableware and drinking utensils. The origin of the name tinplate Tinplate, also known as tinplate in the early days, should be officially called tinplate steel sheet. Because the first batch of foreign iron in China was imported from Macau in the mid Qing Dynasty, which was transliterated as "Ma Kou" at that time, Chinese people generally referred to it as "Ma Kou". Tinplate originated in Bohemia (now within the Czech Republic and Slovakia). The area has been rich in advanced metal craftsmanship since ancient times, and knows how to use hydraulic power for machine manufacturing. It has been producing tinplate since the 14th century. For a long period of time, this place has been the main producer 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 industry, but due to the need for large amounts of funding, it was delayed in development. It was not until 1811, when Brian Downing and John Hall founded canned tinplate food, that tinplate manufacturing began to develop on a large scale. Nowadays, the world produces about 250000 tons of tin annually, with over one-third used to manufacture tinplate, most of which is used in the canned food industry.
