BAg-2a vs BVAg-32 — frequently asked

Is BVAg-32 stronger than BAg-2a?

Yes. BVAg-32 has a typical yield strength of 230 MPa (33.4 ksi) against 210 MPa (30.5 ksi) for BAg-2a — about 10% more. Tensile strength is 400 MPa (58 ksi) vs 400 MPa (58 ksi).

Which is cheaper, BAg-2a or BVAg-32?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

When should I choose BAg-2a over BVAg-32?

Pick BAg-2a when the part is bent, formed or impact-loaded, or when weight is the constraint. Pick BVAg-32 when strength drives the design, or when the part sees heat.
