2030 aluminum is a high-strength copper-based alloy engineered for high-speed automatic machining. Its short chip formation and superior surface finish make it a preferred alternative to 2011 when higher mechanical strength is required. Linsy supplies 2030 alloy in bar, tube, sheet, and plate — all backed by mill test certificates.

2030 aluminum is a free-machining alloy in the 2xxx series, containing approximately 3.3–4.5% copper with manganese and magnesium additions. It is designed for high-speed automatic machining operations where short, broken chips and clean surface finishes are essential.
Compared to 2011 (the most common free-cutting alloy), 2030 offers higher tensile and yield strength while maintaining excellent machinability. It is typically supplied in T3 or T4 temper and is particularly suited for precision-turned components, fasteners, and automotive fittings.
2030 is designated as EN AW-2030 under the European standard system and conforms to ASTM B211 for bar products.
Round bar is the most commonly stocked form of 2030 alloy, produced to ASTM B211 standards. Suitable for CNC turning, automatic screw-machine work, and precision shaft applications.

Cold-worked and naturally aged. T3 offers a good balance of strength and machinability. It is the most commonly ordered temper for automatic screw-machine work, where moderate strength with excellent chip formation is needed.
Solution heat-treated and naturally aged. T4 provides the highest tensile strength in 2030 alloy while still maintaining good machinability. Recommended for applications requiring higher load capacity, such as precision shafts and structural fasteners.
| 脾气 | 最适合 | Key Advantage |
|---|---|---|
| T3 | Screw-machine parts, fasteners, fittings | Best machinability with moderate strength |
| T4 | Structural fasteners, shafts, load-bearing parts | Higher strength with good surface finish |
2030 produces short, broken chips during high-speed cutting — a critical requirement for automatic lathe and screw-machine operations. This reduces machine downtime from chip entanglement and improves tool life.
With tensile strength of 340–410 MPa (depending on temper), 2030 exceeds the mechanical properties of most free-cutting alloys. It bridges the gap between pure machinability (2011) and structural performance (2024).
Parts machined from 2030 exhibit a bright, clean surface finish directly after cutting — reducing or eliminating secondary finishing operations such as grinding or polishing.
Like most 2xxx series copper alloys, 2030 has moderate corrosion resistance. It is not recommended for marine or highly corrosive environments without protective coating. Anodizing or chemical conversion coatings can improve surface protection.

2030 aluminum is primarily used for high-speed machined parts: fasteners, automotive fittings, precision shafts, and any component requiring excellent chip formation and clean surface finish after cutting.
No. 2030 is classified as non-weldable for structural purposes. Its copper content and potential lead additions create poor weld characteristics. Mechanical fastening or brazing should be used instead.
T3 is preferred for screw-machine work (best machinability). T4 is preferred for higher-strength structural fasteners and shafts. Both tempers offer good surface finish and short chip formation.
2030 offers higher tensile and yield strength than 2011 while maintaining comparable machinability. If your application requires more load capacity but still needs free-cutting behavior, 2030 is the better choice.
Some 2030 specifications include small lead additions for enhanced chip-breaking. The presence and amount of lead depend on the specific production standard. Check the MTC certificate for exact composition data on your order.
