When did aluminum cans first appear

Aluminum beverage cans first appeared in the late 1950s, and two DWI cans were officially introduced in the early 1960s.

Aluminium cans are developing rapidly, with annual consumption of more than 180 billion by the end of the century, making it the largest category of cans in the world (about 400 billion).

The consumption of aluminum used to make aluminum cans also grew rapidly, from near zero in 1963 to 3.6 million tons in 1997, equivalent to 15% of the world's total use of all kinds of aluminum.

Aluminum cans weight has been reduced, the early 1960 s, each one thousand aluminum cans (including body and lid) weight 55 pounds (about 25 kg), in the mid - 1970 - s to 44.8 pounds (25 kg), in the late 1990 s and decreased to 33 pounds (15 kg), has been reduced to below 30 pounds, more than 40 years ago fell by nearly half.

In the 20 years from 1975 to 1995, the number of 12-ounce cans made of 1-pound aluminum increased by 35%.

According to ALCOA, the amount of aluminum needed per thousand cans dropped from 25.8 pounds in 1988 to 22.5 pounds in 1998 and 22.3 pounds in 2000.

America can enterprise joint sealing machines and other technology constantly breakthroughs, so aluminum cans aluminum thickness has decreased obviously in the United States, from 0.343 mm to 1992 in 1984 to the 0.285 mm and 0.259 mm 1998 many countries especially developed countries, to use after scrap metal cans recycling and utilization are very seriously, metal cans recycling utilization rate is also increasing.

For example, as early as in the 1980s, the recycling rate of aluminum cans in the United States had exceeded 50%. It was 63.6% in 1990, 65.4% in 1994, 66.5% in 1997, 62.5% in 1999 and 62.1% in 2000.

The recycling rate of Japanese aluminum cans increased from 43% in 1990 to 58% in 1993, 70% in 1996, 79% in 1999 and 83% in 2001.
