Abstract: Nickel plays a very important role in our daily life. Although not as well-known as oil, coal and iron ore, the daily use of nickel influenced by its hard but malleable and malleable structure has many benefits to human life.
The nickel itself comes from the remains of plants or organisms that have been buried underground for millions of years, and is a part of metal-like mining products. The silvery nickel was originally thought to be an impurity in copper, but later became a high-value independent metal after research concluded that nickel could be found in meteorites.
1, stainless steel manufacturing
The first use of nickel in everyday life is as an ingredient in stainless steel. Stainless steel furniture generally uses nickel because of its rust-proof properties.
Stainless steel is usually made of iron ore mixed with nickel and chromium, so it is not easily oxidized by water and air. This is why stainless steel does not rust as easily as ordinary iron. As a result, kitchen utensils such as forks and spoons are often made of nickel alloys.
2. Coin making
In addition to being used to make stainless steel, coins are also made of nickel. Indonesian coins are usually made of nickel because it is tough and easy to be shaped. It is well known that Indonesia has two currencies, coins and bank-notes. Some coins circulating in Indonesia are made of nickel.
Compared with aluminum, the material looks denser and heavier. In 2010, Bank of Indonesia introduced a nickel-based coin currency: the Rp1000 denomination.
