Aluminum Extrusion Vs Stainless Steel: Which Is Better?

When it comes to choosing between aluminum extrusion and stainless steel, it's essential to weigh the pros and cons of each material to determine which one suits your needs best. Both materials have their unique features. Continue reading this article and learn to choose the right material for yourself.

Properties of Aluminum Extrusion

Aluminum extrusion is a manufacturing process that involves shaping aluminum by forcing it through a die. The process results in a range of shapes, including bars, channels, angles, tubes, and custom profiles. Aluminum extrusion is lightweight, corrosion-resistant, and has excellent thermal conductivity. It is also recyclable, making it an environmentally friendly option.

Aluminum extrusion offers a high strength-to-weight ratio, making it perfect for weight-sensitive applications. The material is also malleable and ductile, which means it may be easily molded and formed to match precise design specifications. Aluminum extrusion is easily machinable and may be welded, brazed, and soldered.

Properties of Stainless Steel

Stainless steel is a group of iron-based alloys that contain at least 10.5% chromium. The addition of chromium gives stainless steel its corrosion-resistant properties. Stainless steel is also known for its high strength, hardness, and durability. It is commonly used in applications that require resistance to heat, wear, and corrosion.

Stainless steel is available in a variety of grades, each with its own set of qualities. 304, 316, and 430 are the most frequent grades. Grade 304 is the most popular and has great corrosion resistance, although grade 316 is noted for its higher corrosion and heat resistance. Grade 430 stainless steel is a ferritic stainless steel that is frequently used for ornamental purposes.

Applications of Stainless Steel

Stainless steel is a popular material for various applications, including:

Medical equipment: Because of its sanitary characteristics and corrosion resistance, stainless steel is often utilized in the manufacturing of medical equipment.

Food processing: Stainless steel is widely used in the food processing industry due to its resistance to corrosion, heat, and wear.

Marine applications: Stainless steel is commonly used in marine applications due to its resistance to corrosion from saltwater.

Architecture: Stainless steel is used in architecture for its aesthetic appeal and durability.

Automotive: Stainless steel is used in the automotive industry for various applications, including exhaust systems, engine components, and body panels.

Costs of Aluminum Extrusion Vs Stainless Steel

The cost of aluminum extrusion and stainless steel varies depending on the grade and the quantity needed. In general, aluminum extrusion is more affordable than stainless steel. The price of aluminum extrusion is influenced by the cost of raw materials, manufacturing, and finishing processes. Stainless steel, on the other hand, is more expensive because of the high expenses of manufacturing, which include raw materials, labor, and finishing procedures.


Both aluminum extrusion and stainless steel have unique properties. The choice between aluminum extrusion and stainless steel depends on your need and your budget.
