What is 2030?
2030 (EN AW-2030, AlCu4PbMg) is a free-machining 2000 series Al-Cu alloy with Pb and Bi additions, supplied mainly as extruded or drawn bar. In T3, T4 and T8 tempers it reaches strength close to 2024 while machining comparably to free-cutting brass, which suits high-volume CNC turning of hardware, hydraulic fittings, threaded components and instrument parts. Fusion weldability is very poor and corrosion resistance is low, so parts need coating or anodizing, and the lead content restricts use in RoHS and potable-water applications. Lead-free 6262 is the usual substitute. 2030 has a density of 2.82 g/cm³ (0.102 lb/in³), heavier than 89% of aluminum grades. It melts at 510°C (950 °F). 2030 has a yield strength of 285 MPa (41.3 ksi) and a tensile strength of 400 MPa (58 ksi) — stronger than 73% of aluminum grades. Elongation at break is 12% and the elastic modulus is 73 GPa (10.6 Msi).

Working with 2030
Is 2030 easy to machine?
Outstanding for high-speed automatic turning — free-breaking chips, mirror-like bores; use sharp positive-rake carbide, high speed, light lubricity coolant, and collect Pb-bearing chips separately.
Can 2030 be welded?
Not recommended for fusion welding (hot cracking from Pb/Bi and high Cu); join by threading, press fitting, riveting or adhesives, or use friction/resistance methods with qualification.
Can 2030 be formed, bent or molded?
Formability is limited in T3/T4/T8; do bending and heading in O or freshly solution-treated condition and keep radii generous.
Manufacturability
The process limits FabDigit applies to 2030. Every 2030 part is priced by an engineer; design inside these and the quote comes back without a redesign loop.

What surface finishes work on 2030?
Requires protection: chromate/Ti-Zr conversion coat plus paint or hard anodize; decorative or clear anodizing is streaky, and electroplating needs a specialised pre-treatment for the Pb phase.
