Japanese ultra-thin beer tin plate

In the whole beverage cans market in Japan, steel tanks accounted for 56.6% and aluminum cans only accounted for 43.4%. The number of steel cans was 21.57 billion steel cans and 16.56 billion aluminum cans. However, in the Japanese beer can market, aluminum cans have an absolute advantage. Steel cans can be said to be insignificant. The proportion is 99.3% for aluminum cans and 0.7% for steel cans.
Due to the low cost of tin plated cans compared to aluminum cans, Japan Steel Corporation attempted production of tin plated cans. The impurities in the steel are first removed to make the steel extremely ductile, and then rolled into a very thin steel plate with a special rolling mill. The ultra-thin tin plate made of beer tank wall thickness of only 0.19mm, its weight 30g lighter than ordinary steel beverage cans. However, the open end is still made of aluminum. It is said that such cans are cheaper than aluminum cans and can be recycled like aluminum cans. Although the open end of the can is aluminum, this does not affect the recycling of the cans, because aluminum must be added as a deoxidizer in the steelmaking process. The aluminum on the can just serves as a deoxidizer.
At present, Japan Iron and Steel Company has sold 72 million such trial products for the packaging of low malt beer, which is sold in the northern city of Kyushu in southern Japan.
