The 2000 series aluminum alloys are widely recognized as “hard alloys” due to their remarkable strength and durability. At Linsy Alu, we focus on producing high-quality alloys that meet the demands of industries requiring superior mechanical properties. These alloys are mainly aluminum-copper alloys containing about 2% to 10% copper along with trace amounts of other elements. The addition of copper allows for precipitation hardening, a process that enhances hardness and overall strength.
While copper improves mechanical performance, it can slightly reduce corrosion resistance and formability. However, the 2000 series alloys continue to be one of the most trusted choices for applications requiring high performance and structural integrity. With proper treatment and protective finishes, they remain an essential material across multiple industries.
Key Properties of 2000 Series Aluminum Alloys
The alloys in this series combine exceptional strength, good machinability, and the ability to undergo heat treatment for added performance. Their strength-to-weight ratio makes them ideal for heavy-duty uses while keeping structures lightweight.
- High strength and toughness suitable for critical parts
- Heat treatable for better mechanical properties
- Good wear resistance for long-lasting use
- Moderate corrosion resistance, usually improved with protective coatings
2024 Aluminum: The Workhorse Alloy
Among the 2000 series, 2024 Aluminum is one of the most widely used. Known for its excellent fatigue resistance and high strength, it is often chosen for aircraft structures, automotive parts, gears, and aerospace fittings. Despite its moderate corrosion resistance, when properly treated, 2024 aluminum performs reliably under demanding conditions. At Linsy Alu, we supply 2024 aluminum bar, sheets, and plates that meet strict industry standards.
2219 Aluminum: High Performance Under Heat
2219 Aluminum stands out for its excellent weldability and ability to maintain strength at elevated temperatures. This makes it a preferred material in the aerospace and defense industries, especially in areas where parts are exposed to high thermal stress. It is commonly used in fuel tanks, structural components, and space vehicle parts. The high fracture toughness of 2219 Aluminum ensures safety and long service life, which is why it remains a top choice for critical engineering applications.
Aluminum Bar Applications
Aluminum bar products made from 2000 series alloys are essential across industries. Their versatility and durability make them useful in manufacturing strong screws, bolts, gears, clock parts, and welding filler wires. In construction and transportation, aluminum bars provide lightweight yet powerful solutions. At Linsy Alu, we produce precision Aluminum bar designed to deliver maximum performance in high-demand environments.
