What Is a Nickel?

When you hear the word “nickel”, your first thought might be of a coin, especially in the United States and Canada. But in the industrial world, nickel refers to something far more valuable — a versatile, corrosion-resistant metal that is essential to modern technology and manufacturing.

In this article, sasaalloy explores what nickel is, where it comes from, and how it’s used across multiple industries. Whether you’re an engineer, product designer, or material buyer, understanding nickel’s role in alloys and materials science can help you make better sourcing and design decisions.

What Is a Nickel?

In metallurgy and materials science, nickel is a silvery-white transition metal with the atomic number 28 and symbol Ni. It is known for its:

• High corrosion resistance

• Ductility and strength

• Magnetic properties

• High-temperature performance

Nickel is not a rare element — it ranks as the fifth most common element on Earth by mass. It is commonly found in nickel sulfide ores and laterite ores, and is mined in countries like Indonesia, the Philippines, Russia, and Canada.

Nickel in Currency: The Coin Version

A nickel is also the name of a five-cent coin in several countries, especially in North America. These coins are not made of pure nickel but typically contain a nickel-copper alloy. For example:

• U.S. nickel: 75% copper, 25% nickel

• Canadian nickel (pre-1982): mostly pure nickel

• Newer coins often use cheaper materials like plated steel for cost savings

Although relevant in currency, this form represents only a small portion of global nickel usage.

What Makes Nickel Unique as a Metal?

1. Corrosion Resistance

Nickel naturally forms a thin oxide layer that protects it from moisture and air. This makes it essential for marine, chemical, and outdoor environments.

2. Magnetic Behavior

Nickel is ferromagnetic, meaning it can be magnetized. It is used in magnetic shielding and electrical applications.

3. High-Temperature Strength

Nickel maintains its mechanical properties at elevated temperatures, making it ideal for jet engines, turbines, and furnaces.

4. Alloy Compatibility

Nickel blends well with metals like chromium, molybdenum, iron, and copper, creating high-performance alloys.

Common Uses of Nickel

Nickel is not typically used in pure form for commercial applications. Instead, it is alloyed with other metals to create high-performance materials. Here are the top uses of nickel:

1. Stainless Steel Production

Nickel is a core ingredient in 300-series stainless steels, such as 304 and 316. These steels are used in:

• Food processing equipment

• Medical devices

• Kitchen appliances

• Construction and architecture

2. Nickel Alloys

Nickel-based alloys like Inconel, Monel, and Hastelloy offer exceptional performance in corrosive and high-heat conditions. These alloys are used in:

• Aerospace engines

• Chemical plants

• Oil & gas pipelines

• Nuclear power systems

sasaalloy specializes in supplying a wide range of these nickel-based alloys to meet your exact industrial needs.

3. Battery Production

Nickel is used in lithium-ion and nickel-metal hydride batteries, powering:

• Electric vehicles (EVs)

• Smartphones

• Power tools

• Renewable energy storage systems

Nickel-rich battery chemistries, such as NMC (Nickel Manganese Cobalt), offer high energy density and stability.

4. Electroplating

Nickel coatings are applied to enhance appearance, corrosion resistance, and wear performance. Applications include:

• Automotive parts

• Decorative finishes

• Industrial equipment
