Question 1

1. Where does aluminum come from and what is it made ?

Accepted Answer

Aluminum is a type of metal made from bauxite ore, which is naturally found in the earth. Bauxite is typically yellowish-brown to reddish-brown in color, resembling hard clay lumps, with aluminum compounds inside. Pure aluminum is extracted through the Bayer Process, which is widely used in the global industry. Once pure aluminum ingots are obtained, aluminum factories or aluminum coil mills further process them into a wide range of aluminum products available on the market.

Question 2

2. What are the properties of aluminum ?

Accepted Answer

Aluminum is a metal that is about one-third the weight of steel, thanks to its low density, yet it has high load-bearing capacity. It is tough, ductile, and flexible, making it easy to bend and shape. Aluminum is also highly resistant to rust, bending, cracking, corrosion, and heat. These qualities make it a widely used material in engineering and various industries today.

Question 3

3. How many grades of aluminum are there ?

Accepted Answer

Aluminum grades or quality classifications vary depending on alloying elements and heat treatment. Each grade has unique properties and is identified by a number series, for example:

1XXX : Aluminum with over 99% purity
2XXX : Aluminum-copper alloys
3XXX : Aluminum-manganese alloys
4XXX : Aluminum-silicon alloys
5XXX : Aluminum-magnesium alloys
6XXX : Aluminum-magnesium-silicon alloys
7XXX : Aluminum-zinc alloys
8XXX : Aluminum with other elements such as nickel, titanium, chromium, or lead
