Aluminum vs Stainless Steel Steel Pipe and Tubing
Steel pipe and tubing are used in automotive, aerospace, industrial, architectural, research, and medical applications. The most common materials are aluminum and stainless steel, each with attributes suited to different industries. Once you've determined whether you need piping or tubing, the next step is choosing the best metal for your application.
Choosing the Right Metal
When choosing a tubing material, both aluminum and stainless steel come in a variety of alloys and tempers, each with unique properties. Each metal has general properties applicable to all its alloys.
Mechanical Properties
Consider the mechanical properties required for your application. For strength, stainless steel offers a good strength-to-weight ratio and can be strengthened by cold working. If minimizing weight is important, aluminum may be better. Aluminum is one-third lighter than stainless steel of the same dimensions.
Corrosion Resistance
Corrosion and heat resistance are also important factors. Both stainless steel and aluminum offer corrosion protection, varying by alloy. Passivating oxide films on both metals' surfaces help prevent corrosion.
Heat Resistance
Passivation can inhibit electrical conduction, making stainless steels less conductive. Aluminum, with high electrical and thermal conductivity, is used in power transmission lines. For electricity or heat conduction, aluminum may be better. Stainless steels with high chromium and nickel retain strength at high temperatures, while aluminum’s tensile strength increases at lower temperatures.
Is Stainless Steel the Same as Aluminum?
To choose the best metal for your application, consider mechanical properties, corrosion resistance, and heat resistance. Once a metal category is chosen, select the alloy and temper needed.
Stainless Steel 101
Stainless steel offers various grades for different applications. The most common grades are T304 and T316, part of the 300 series of stainless steel alloys. T304 is the classic stainless steel alloy containing 18% chromium and 8% nickel. T316, familiar in food service and medical applications, includes molybdenum for additional corrosion protection.
Alloy properties depend on heat treatment and cold working history. Consult a metallurgist or tubing specialist for the right combination of alloy and processing for your application.
Stainless steel tubing comes in fractional and metric outer diameters (ODs) ranging from 1/16 to 8 inches, and as small as 0.008 inches for hypodermic applications. Fabrication can include bending, coiling, end forming, welding, and cutting.
About 50% of all new stainless steel is fabricated from recycled steel scrap.
Aluminum ABCs
Common aluminum alloys for tubing and pipe include 2024, 3003, 5052, 6061, and 7075. Each alloy has unique attributes due to elements like copper, manganese, magnesium, silicon, and zinc.
Alloys 2024, 6061, and 7075, known for high strength-to-weight ratios and fatigue resistance, are used in aircraft structures. Untreated 2024 and 7075 are prone to corrosion, while 6061 is corrosion-resistant and easier to weld. 7075 offers higher strength but is costlier.
Alloy 3003 is good for corrosion resistance and strength, while 5052 is highly weldable for joint applications.
Aluminum alloy properties also depend on temper or heat-treatment history. Temper O indicates the highest ductility and lowest strength, while Tempers T3, T4, and T6 involve heat treatments and cold working or aging to strengthen the metal.
Specify size and any additional fabrication operations once the right aluminum alloy and temper are chosen. Aluminum tubing ODs range from 0.062 to 3.00 inches with wall thicknesses from 0.010 to 0.250 inches. After a long service life, aluminum tubing can be recycled, as it is made from 99.8% pure aluminum alloy.
