FAQ’s About Aluminium Products
What makes aluminium a good material for industrial use?
Aluminium combines low weight, natural corrosion resistance, and strong conductivity, making it suitable for structural, electrical, and fluid-handling applications where steel would add unnecessary weight.
What are the main grades of aluminium available?
Aluminium is grouped into series from 1xxx to 7xxx, each defined by its primary alloying element — ranging from pure aluminium for conductivity to zinc-alloyed grades for aerospace-level strength.
Can aluminium pipes and fittings be welded?
Yes. Most aluminium alloys can be welded using TIG or MIG processes with a compatible filler alloy, though certain high-strength 2xxx and 7xxx grades require careful heat-treatment control after welding.
Do you supply custom sizes and shapes of aluminium products?
Yes. Beyond standard catalogue sizes, we manufacture aluminium products to custom diameters, wall thicknesses, lengths, and finishes based on project drawings.
