AiSi Tin Plates Boost Brand Visibility and Consumer Appeal

Tin plates can be shaped and curved easily with minimal maintenance. They also have built-in corrosion resistance that protects the metal from damage by harsh elements.

Tinplate (SPTE) is a cold-rolled low carbon steel sheet or strip coated with commercial pure tin on both sides. It combines the strength and formability of steel with the tin’s non-toxicity, corrosion resistance, and solderability.

Corrosion Resistance

Tin is a soft, shiny metal with excellent corrosion resistance. It’s also a low maintenance material that requires only routine inspection and periodic painting. It can be used alone or combined with harder metals such as iron and steel to produce tin-plated steel (or tinplate), which is an industrial product widely used for containers, fabricated goods and electrical machinery components.

Electrolytic tinplate is made of cold-rolled steel that is coated with commercial pure tin on both sides. It’s a low-carbon, high strength, highly formable material that offers great printability and paintability, and is suitable for welding and soldering. It is a common choice for producing food cans, beverage cans and 18-liter cans, but also has many other applications such as artistic cans.

The tin coating on electrolytic tinplate is normally oiled, and almost always with the chemical acetyl tributyl citrate or ATBC. This oil minimizes scratching of the tin surface during handling and transit. It is also used to help prevent rusting on the steel substrate when exposed to an Quenched and tempered steel strip alkaline medium such as rainwater or H2SO4. The results of tape-peeling tests and retort treatment on EZPTM and conventional tinplate are shown in Figures 7 through 10. Commercial electrolytic tinplate of various proportions of martensite has ATC values that are similar to those of conventional ferritic tinplate.

Formability

Formability is the ability of a sheet metal to transform into a desired shape without failure or excessive thinning. This is determined by the forming limits of the material and the type of forming operation. The forming limits of a material are a function of the strain hardening exponent n, the material microstructure, and the grain size.

This paper analyzes the formability of AISI 304L steel alloy sheets by comparing the deep drawing and stretch forming processes. The mechanical properties of the sheets were measured using a servo-electric hot forming machine and tested at 0.1,0.01 mm/s strain rates. The results were compared with those of a similar tensile test.

Tinplate is a thin steel plate coated with commercial pure tin on both sides. It is used in containers for food, beverages, paints, aerosols and other chemical products. The tin coating provides corrosion resistance and makes the containers easy to solder and weld. It also has high strength and ductility. The tinplate manufacturing process is complex and involves several steps. It is important to understand the effect of the different processes on the tinplate’s formability.

Durability

Tinplate is a durable metal with excellent corrosion resistance and formability. It is commonly used in the food and beverage industry to make all types of containers including 18-liter cans, decorative tins, and promotional packaging. Its ability to showcase branding and artwork makes it a versatile packaging material that boosts brand visibility and consumer appeal.

The production process of tinplate begins with cold rolled low carbon steel that is then annealed, Hardened & Tempered Steel Strip Supplier skin passed, and electrolytically tin-plated. This produces a thin metallic layer of commercial pure tin that is durable, tasteless, and nontoxic. It is also very strong and ductile, making it suitable for use in a variety of applications including cans, closures, deep-drawn oil filter shells, and metal hoses.

The tin mill product is then electrostatically oiled, and this oil prevents scratching of the tin surface in transit and handling. This oil is typically acetyl tributyl citrate or ATBC. The tinplate is then recoiled at the exit end of the electrolytic tin line onto a take up reel that is most often 16-1/2 inches in diameter.

Recyclability

With sustainability as one of the newest trends, it is important to consider how our packaging is made. Whether it’s ravioli to satisfy that late night hunger or spray whipped cream to make the perfect cake topping, our everyday products come in tinplate cans. Tinplate is an incredibly sustainable and environmentally conscious choice of packaging.

The tin plate coating on the base steel is electrolytically applied and offers excellent metallurgical bonding to the substrate metal as well as uniformly controlled thickness. The tin coating also provides a high level of corrosion resistance that protects the contents from environmental influences.

In Germany alone, tinplate is recycled at an astonishing rate of 95 percent. This sends a clear signal to the filling industry, trade and consumers that tinplate is a packaging material that can be used in a closed, effective recycling cycle.

In addition, the cold reduction process that is used in tinplate production helps to make it even more environmentally friendly. During this process, the steel sheets are cooled down with precision and care to ensure they remain pure and free of contaminants such as oxides from the previous step of temper rolling.

Environmentally Friendly

Tinplate is a sustainable and environmentally conscious packaging material that is a popular choice in many industries. It can be used to make food, beverage, and aerosol containers, among other products. It is also safe to use and provides optimum protection for foods. The tin coating can help keep products fresh and safe from oxygen and light, making it ideal for long-term storage and shipping.

The tin plate manufacturing process has undergone significant innovation in recent years. It is now possible to produce tinplate that requires less energy and produces fewer emissions, making it more environmentally friendly. Additionally, tinplate is recyclable, which can reduce the need for new ore mining.

While tinplate is recyclable, it may be necessary to remove pinholes or off-gauge materials before recycling. In addition, tinplate should be cleaned thoroughly before reprocessing to avoid contamination of the finished product. The cleaning process involves a series of steps, including washing with a combination of alkaline phosphates and silicates and drying with hot air. Alternatively, the tinplate can be passivated in a sulfuric acid solution.
