What is aluminum alloy? The benefits it brings

Aluminum alloys are widely used in life, especially in electronic equipment, electrical appliances and parts – accessories in the mechanical industry. Let’s find out with Tnhelearning.edu.vn what aluminum alloy is as well as the benefits it brings!

What is aluminum alloy?

Aluminum alloy is a metal compound containing the most aluminum component along with some other metal components such as manganese, copper, magnesium, silicon, … and tin. Therefore, the material possesses the characteristics of aluminum and other metal components used in combination.

For example, other metal components will have properties such as:

• Copper : Helps to improve durability and for easier formability.
• Silicon : Increases melt flow, lowers melting temperature and improves moldability of the finished product.
• Manganese : Supports increased endurance and flexibility.
• Magnesium : Helps improve durability and provides corrosion resistance.
• Magnesium and Silicon : Increases tensile strength, product forming and has high strength.

Outstanding properties of aluminum alloy

It can be said that, depending on the metal composition combined with aluminum, aluminum alloy has the following outstanding properties:

High strength with good corrosion resistance

Thanks to the oxidizing properties of aluminum alloy, it turns the surface layer of aluminum into aluminum oxide with good tightness and good resistance to corrosion in the air.

Moreover, to enhance the oxidation resistance, people also carry out anodizing process of dyeing aluminum to make this aluminum oxide layer thicker, thereby creating aluminum alloy items with better durability such as wheels. aluminum, aluminum kettle, aluminum pot, …

Good electrical and thermal conductivity

Aluminum alloys have good electrical and thermal conductivity after silver, copper and gold.

Moreover, the melting point of aluminum alloy is relatively low , which makes it convenient for smelting to cast and fabricate into many products such as household appliances that conduct electricity well, which saves cooking time and fuel (or electricity) consumption.

Easy to shape and mold

Aluminum alloy has ductile properties, so it is convenient for casting, drawing into film, sheet, wire, foil or extruding into bars convenient for the production of utensils. Only need to heat about 550 – 660 degrees Celsius , the aluminum alloy will be melted and one can create the desired product shape.

Some applications of aluminum alloy in life

Aluminum alloy, like other metals, is widely used in life, in order to better serve the needs of people. Specifically, aluminum alloys are used in:

• Shipbuilding production : Thanks to its effective anti-corrosion properties, aluminum alloys are used in the manufacture of a number of marine ship components such as hydraulic hoses and other parts of ships that are frequently exposed to seawater.
• Medicine : Thanks to its stiffness, lightness and good bearing capacity, aluminum alloys are used to make prosthetics for the disabled.
• Mechanical industry : Aluminum alloy is used to manufacture spare parts of means of transport (such as bicycles, motorcycles, cars), production machinery, etc.
• Aerospace industry : With its durable, lightweight and highly aesthetic properties, aluminum alloys are often used to make the shell – fuselage and some aircraft machinery.
• Household appliances : Pans, pots and pans, baskets, air fryers, etc.
• Furniture : Tables and chairs, stairs, gates, doors, aluminum ladders,…
• Electronic equipment : Aluminum alloy is often used to make phone cases, laptops, tablets, watch frames, … and some of the components in those devices.

So, you already know what aluminum alloy is as well as the benefits it brings to life. When choosing utensils made of aluminum alloy, you should pay attention to the ratio of ingredients and read the product instructions carefully to achieve the longest possible product life!
