Values for the AS-BRAZED condition
What is BAg-36 AS-BRAZED?
BAg-36 AS-BRAZED is BAg-36 heat treated to AS-BRAZED — property set for the solidified fillet/joint used in design calculations rather than the supplied wire. BAg-36 AS-BRAZED has a yield strength of 220 MPa (31.9 ksi) and a tensile strength of 400 MPa (58 ksi) — stronger than 67% of precious metal grades. Elongation at break is 20% and the elastic modulus is 90 GPa (13.1 Msi). BAg-36 AS-BRAZED has a density of 9.1 g/cm³ (0.329 lb/in³), lighter than 89% of precious metal grades. It melts at 640°C (1,184 °F).
Advantages
- Lightweight — 9.1 g/cm³ (0.329 lb/in³), better than 89% of precious metal grades
- Low embodied carbon — 65 kg CO₂/kg, better than 78% of precious metal grades
Limitations
- Limited service temperature — 200°C (392 °F), worse than 89% of precious metal grades
- Needs corrosion protection — 60/100, worse than 88% of precious metal grades
- Limited ductility — 20%, worse than 77% of precious metal grades
- Hard to polish — 70/100, worse than 76% of precious metal grades

Working with BAg-36 AS-BRAZED
Is BAg-36 easy to machine?
Not a structural machining material; the soft deposit smears — remove excess fillet by grinding or filing rather than turning.
Can BAg-36 be welded?
Used as a brazing filler itself: braze at 680–760 °C with a white flux (AWS FB3-A/3-C), heat the parent metal not the wire, and keep dwell short to limit zinc fuming.
Can BAg-36 be formed, bent or molded?
Excellent cold drawability and rollability in the annealed state; hard-drawn wire should be re-annealed before tight ring forming.
What surface finishes work on BAg-36?
Fillets can be polished to a silver-white finish; remove all residual flux by hot-water quench or acid pickle to prevent glassy residue and later corrosion.
BAg-36 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| AgAWS A5.8 / UNS P07454 | 44 – 46 | 45 |
| Cu | 26 – 28 | 27 |
| Snreplaces Cd for melting-point and flow control | 2 – 3 | 2.5 |
| Cdcadmium-free limit | ≤ 0.01 | |
| Other (total)total other elements | ≤ 0.15 | |
| Zn | balance |
BAg-36 AS-BRAZED — frequently asked
What is BAg-36 AS-BRAZED used for?
BAg-36 AS-BRAZED is typically used for general fabrication brazing, HVAC and refrigeration and cadmium-restricted shop environments. In short: 45% silver, cadmium-free; lower brazing range than BAg-35; improved flow and wetting.
What is the yield strength of BAg-36 AS-BRAZED?
BAg-36 AS-BRAZED has a typical yield strength of 220 MPa (31.9 ksi) and a tensile strength of 400 MPa (58 ksi) — stronger than 67% of precious metal grades.
