One of the main uses for iron is for cooking appliances like skillets because the pores in iron allow it to prevent food from sticking to it. It also has a high melting point so it works great for use as a wood stove.

Due to the density and weight of iron, it is also widely used for manufacturing heavy machinery. Being so heavy and rigid prevents vibrations which makes it perfect for producing heavy equipment.

Steel

Steel stands as the preeminent types of metal in modern engineering and construction, thanks to its unparalleled blend of strength, durability, and versatility. This marvel of metallurgy is an alloy primarily composed of iron and carbon, with the carbon content serving a critical role. It functions to purge the iron of impurities and residual elements that could otherwise compromise its integrity and performance.

Iron, in its pure state, boasts commendable strength and utility across various applications. However, its high density, coupled with a natural susceptibility to corrosion and rust upon exposure to moisture, significantly limits its efficacy and reliability as a building material. These inherent shortcomings not only present challenges in maintenance but also raise questions regarding its suitability for long-term structural applications. Because of the strength-to-weight ratio of steel, it is coveted for building parts for machinery as well as its use in constructing buildings.

There are over 3,500 grades of steel, so no matter what you are building there is a good fit for you. This is a big reason why steel is the most used metal in the world.

Here are some of the most popular types of steel on the market, and the best applications for each. For an even deeper dive on steel, check out our article on the different types of structural steel.

Stainless Steel

Stainless steel is made by mixing iron, carbon, and chromium. Renowned for its resistance to corrosion and oxidation, stainless steel is a staple in kitchen appliances, medical equipment, and architectural facades. Its aesthetic appeal coupled with low maintenance requirements make it a preferred choice for a wide range of decorative and functional applications.

Alloy Steel

Alloy steel comes from mixing iron with a number of other types of metal. By incorporating elements such as chromium, nickel, and molybdenum, alloy steel offers enhanced properties like improved corrosion resistance and greater strength at high temperatures.

Because it is so customizable, it is popular for use in building projects. You can customize it to suit whatever use you require, and is pretty inexpensive to produce. This makes it suitable for use in pipelines, automotive parts, and power generation equipment.

Carbon Steel

Carbon steel comes from combining iron with carbon. This is the most basic form of steel, categorized based on carbon content into low, medium, and high. Low carbon steel is ideal for construction due to its excellent weldability and malleability. Medium carbon steel finds its use in automotive components owing to its balance of strength and ductility. High carbon steel, with its superior hardness, is favored for cutting tools and wear-resistant applications. It is customizable based on the amount of carbon that is added. Depending on that, it is sorted by category into high, medium, or low carbon steel.

More carbon that is used makes harder steel. On the flip side, using less carbon will provide less expensive steel that is easier to create. The most common use for carbon steel is as a building material because of its strength.

Tool Steel

Tool steel is one of the hardest forms of metal on the planet. Tool steel is made by combining iron with cobalt, tungsten, or vanadium. Because of its hardness, it is great for use in the manufacturing of cutting tools, dies, and molds.

For intermediate needs, consider galvanized carbon steel, which offers enhanced corrosion protection at lower cost than stainless steel.

How do different metals compare in terms of environmental sustainability?

Metals vary significantly in their environmental profiles. Steel has the highest recycling rate of any material worldwide (over 85% for structural steel) and can be recycled indefinitely without quality degradation, with recycled production requiring 60-70% less energy than virgin material. Aluminum has excellent recyclability (requiring only 5% of the energy of primary production) but higher impact in virgin production due to energy-intensive refining. Stainless steel combines good recyclability with exceptional longevity, often serving 50+ years without replacement. Copper and brass feature high reclamation rates due to their value. When assessing environmental impact, consider the complete lifecycle including production energy, longevity in service, maintenance requirements, and end-of-life recyclability rather than focusing solely on initial embodied energy.

What factors affect the cost and availability of different metal types?

Metal pricing and availability are influenced by several key factors: raw material costs (including mining/extraction expenses and scrap prices), energy costs for production (particularly significant for aluminum), global supply and demand dynamics, trade policies and tariffs, transportation costs, processing requirements, and alloy complexity. Commodity metals like carbon steel typically experience more price volatility than specialty alloys with more stable demand. In recent markets, supply chain disruptions have created availability challenges for certain products. Bushwick Metals maintains extensive inventory across metal types to buffer against market fluctuations, but for project planning, consider that specialized grades or uncommon dimensions may have longer lead times and different price structures than standard products.

How do welding and fabrication requirements differ between metal types?

Different metals present distinct fabrication challenges. Carbon steel offers excellent weldability with standard processes but requires cleaning of mill scale for optimal results. Stainless steel demands specific filler materials matching the base metal grade, controlled heat input to prevent sensitization, and thorough cleaning to prevent contamination. Aluminum requires specialized techniques including AC TIG welding or specific MIG processes due to its oxide layer and high thermal conductivity. For cutting, carbon steel processes well with plasma, laser, or oxy-fuel methods, while stainless typically requires plasma or laser cutting. Aluminum demands careful feed rates during machining to prevent galling. These differences significantly impact fabrication efficiency, equipment requirements, and labor costs, making fabrication compatibility an important consideration during material selection.
