Precious Metal BAg-2a vs BAg-36

Precious Metal · grade comparison

Precious Metal BAg-2a and BAg-36 are both precious metal grades. Both yield at about 210 MPa — strength does not separate them. BAg-36 is harder — 100 HV against 95 HV for BAg-2a — which matters for wear surfaces and threads. BAg-36 is lighter (9.1 g/cm³ vs 9.4 g/cm³ for BAg-2a) and BAg-36 conducts heat better (100 W/m·K vs 75 W/m·K).

BAg-36Choose it when surface hardness matters, or when weight is the constraint.

BAg-2a vs BAg-36 — frequently asked

What is the difference between BAg-2a and BAg-36?

Precious Metal BAg-2a and BAg-36 are both precious metal grades. Both yield at about 210 MPa — strength does not separate them. BAg-36 is harder — 100 HV against 95 HV for BAg-2a — which matters for wear surfaces and threads.

Which is cheaper, BAg-2a or BAg-36?

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 BAg-36?

Pick BAg-36 when surface hardness matters, or when weight is the constraint.
