Precious Metal BAg-2a vs BAg-6

Precious Metal · grade comparison

Precious Metal BAg-2a and BAg-6 are both precious metal grades. Both yield at about 210 MPa — strength does not separate them. BAg-6 is harder — 95 HB against 85 HB for BAg-2a — which matters for wear surfaces and threads. BAg-6 is lighter (9.1 g/cm³ vs 9.4 g/cm³ for BAg-2a) and BAg-2a is stiffer (90 GPa vs 85 GPa). On the shop floor, BAg-6 machines more easily (good vs fair).

BAg-6Choose it when surface hardness matters, or when weight is the constraint.

BAg-2a vs BAg-6 — frequently asked

What is the difference between BAg-2a and BAg-6?

Precious Metal BAg-2a and BAg-6 are both precious metal grades. Both yield at about 210 MPa — strength does not separate them. BAg-6 is harder — 95 HB against 85 HB for BAg-2a — which matters for wear surfaces and threads.

Which is cheaper, BAg-2a or BAg-6?

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.

Which is easier to machine, BAg-2a or BAg-6?

BAg-6. Its machinability rates good (55/100) against fair (45/100) for BAg-2a.
