For any metal fabrication work, there are multiple options of metals to choose from. In the case of aluminium vs steel fabrication in Manipur, you might want to know which metal is more suitable for the fabrication work. Well, both metals are well appreciated for their versatility, durability, corrosion resistance and other promises to withstand the requirements of the fabrication works. Though they are kind of similar in appearance, beyond their superficial look, the two materials hold completely different properties. So, in this article, we are going to weigh the pros and cons of both of these metals against specific requirements. 

The better candidate for metal fabrication 

Let us put these two metals in the light of comparison with each other. And we might be able to draw some conclusions regarding their suitability. 

Strength

Stainless steel is undoubtedly a denser, heavier and stronger material than aluminium. However, despite weighing approximately one-third the weight of steel, aluminium has a much better strength-to-weight ratio than stainless steel. Its lightweight nature and better strength-to-weight ratio have made it a more lucrative option for industries such as the automotive and aerospace industries. On the other hand, owing to its strength and sturdiness, steel is a much better candidate for design and architectural requirements. 

Thermal properties

Stainless steel can withstand much higher temperatures than aluminium. It has exceptional thermal properties, which lend itself well to high-heat applications. It begins to soften at temperatures above 200 degrees Celsius. On the other hand, stainless steel can very well endure temperatures over 400 degrees Celsius. 

Weldability

Here, too, stainless steel triumphs over aluminium. If your job requires frequent welding, in comparison to aluminium, stainless steel is far easier to work with. Due to aluminium’s high thermal conductivity and low melting point, it poses significant challenges to work with. Moreover, stainless steel’s tensile strength is 2-3 times stronger than aluminium. And it can produce welds that are stronger than the parts it joins. 

Industries

Aluminium is known to react with food items. It is extremely likely to leach or dissolve into foods. At high temperatures, it can cause discolouration or flavour changes in the food products. This is precisely why culinary experts and food service companies tend to prefer stainless steel over aluminium. Its non-porous surface is conducive and ideal for applications that require different sanitary conditions, including the manufacturing of cutleries and kitchen equipment. 

All in all, this comparison allows us to discern how stainless steel is a much more agile and flexible material when it comes to the purpose of metal fabrication.
