Aluminum 2030 vs 2199

Aluminum · grade comparison

Aluminum 2030 and 2199 are both aluminum grades. 2199 is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 285 MPa (41.3 ksi) for 2030, about 35% more; tensile strength follows at 450 MPa (65.3 ksi) vs 400 MPa (58 ksi). 2199 is harder — 130 HB against 100 HB for 2030 — which matters for wear surfaces and threads. 2199 is lighter (2.63 g/cm³ vs 2.82 g/cm³ for 2030) and 2199 is stiffer (78 GPa vs 73 GPa). On the shop floor, 2030 machines more easily (excellent vs good), 2199 welds better (poor vs not recommended), and 2030 sits in a lower cost tier (premium, $$$) than 2199 (high, $$$$).

2030Choose it when the part is machined in volume, or when cost is the deciding factor.

2199Choose it when strength drives the design, or when surface hardness matters.
