Cast Aluminium Products
Aluminium is the world’s most abundant metal, third most common element and its versatility makes it the most widely used metal after steel. Worldwide demand increases year on year with ever increasing quantities being produced from recycled aluminium scrap.
The use of recycled aluminium is economically and environmentally compelling as it takes a fraction of the amount of power to remelt and recycle one tonne of used aluminium as it does to produce one tonne of virgin aluminium. There is no difference in quality between virgin and recycled aluminium alloys. All of the aluminium ingots we use at Archibald Young Ltd come from secondary smelting suppliers.
Pure aluminium is soft, ductile and has a high electrical conductivity but alloying with other elements is provides the higher strengths needed for industrial applications. Aluminium is most commonly alloyed with silicon, manganese, copper, zinc, magnesium and lithium. Trace amounts of iron, chromium, titanium, zirconium, lead, bismuth and nickel are also invariably present.
There are hundreds of cast alloy variations, with many of those in common use in foundries around the world. Our Archibald Young foundry regularly casts about half a dozen of these alloy variations but over the years our melting systems have proven adaptable enough to make up a lesser used alloy should our customer needs require it.
