How to choose between cast steel and aluminium corner castings fittings?

Cast steel and aluminium are two for the top materials of choice for modern metal casting. Thousands of manufacturers worldwide rely on both metals for heavy metals and goods that are lightweight and resistant to corrosion.

There are lots of factors to decide which is best when it comes to cast steel and aluminium corner casting fittings. Let's have a comparison and figure out which one is the best!

Aluminium Vs Cast Steel: Strength

Steel is usually stronger than aluminium, but certain aluminium alloys are stronger than some forms of steel. Steel is also the first option for weight-bearing structural elements or applications that need significant strength to operate. aluminium has weight advantages, but it must be carefully designed to meet strength specifications.

Winner: Cast Steel

Aluminium Vs Cast Steel: Corrosion Resistance

This could go either side, depending on the alloys involved. aluminium is inherently corrosion resistant and can endure long periods of time outdoors and in wet conditions. Cast steel is easily corroded and often needs to be painted or sealed to work properly.

In reality, it is a common misconception that aluminium does not corrode. While aluminium does not rust (the red color of rust is caused by iron in the alloy), it will corrode faster than other alloys when exposed to acidic or basic environments.

Aluminium Vs Cast Steel: Cost

The cost of different alloys varies greatly, and the global market is constantly changing. Cast Steel is made from iron ore and carbon, while aluminium is made from bauxite ore. Both are relatively similar, but iron is usually less costly to obtain. Both metals can also be recycled, which is also less expensive than producing new raw materials. aluminium is generally more expensive than cast steel.

Winner: Cast Steel

Aluminium Vs. Cast Steel: Heat Resistance

Since aluminium has a much lower melting temperature than cast steel, aluminium products are not as heat resistant. Although cast steel does not melt until temperatures reach about 2500 degrees F, aluminium starts to soften significantly at 900 degrees F. As a consequence; cast steel can be used in high-heat applications that aluminium cannot.

Winner: Cast Steel

As we have looked into different factors, it is clearly justified that cast steel is the best material type that one should look for when buying corner castings for iso shipping container corners.
