In Australia, aluminium is one of the most widely used materials in the manufacture of windows and doors. Its popularity can be attributed to its excellent properties, such as durability, strength, versatility, and low maintenance requirements. Aluminium windows and doors offer various benefits, including energy efficiency, design flexibility, and resistance to corrosion. Here are some of the top aluminium materials used in window and door manufacturing in Australia:
- 6063-T5 Aluminum Alloy: This alloy is commonly used for residential and commercial window and door frames. It has excellent extrudability, which means it can be easily shaped into different profiles and sizes. The 6063-T5 alloy offers good corrosion resistance and is suitable for various finishes, such as powder coating or anodizing. It is also known for its structural strength and ability to withstand harsh weather conditions.
- 5005 Aluminum Alloy: This alloy is often utilized for window and door frames in coastal areas due to its superior corrosion resistance. The 5005 alloy contains magnesium, making it highly resistant to salt water and other environmental factors. It is frequently chosen for applications where exposure to moisture or coastal environments is a concern.
- 5083 Aluminum Alloy: While primarily used in marine applications, the 5083 alloy is also suitable for specialized window and door manufacturing. Its exceptional strength, combined with high corrosion resistance, makes it an ideal choice for areas prone to severe weather conditions or environments with high humidity levels. The 5083 alloys are often used in regions experiencing cyclones, tropical storms, or heavy rainfall.
- 6061-T6 Aluminum Alloy: This alloy offers an excellent strength-to-weight ratio, making it suitable for large-scale or heavy-duty window and door frames. The 6061-T6 alloy provides structural integrity and is commonly used in commercial buildings or high-rise constructions. It offers good corrosion resistance and can withstand high winds and other external forces.
- Thermally Broken Aluminum: Thermal break technology is commonly employed in aluminium windows and doors to enhance energy efficiency. A thermal break is a non-metallic material (usually polyamide) inserted between the interior and exterior aluminium profiles. This technology minimizes heat transfer, improving insulation and reducing energy consumption. Thermally broken aluminium systems are widely used in energy-efficient residential and commercial constructions.
It’s important to note that these are just a few examples of aluminium materials used in window and door manufacturing in Australia. The specific choice of material depends on various factors, including the desired performance, design requirements, budget considerations, and environmental conditions. Manufacturers in Australia utilize a range of aluminium alloys to meet the diverse needs of the market and ensure long-lasting, high-quality windows and doors.
