What is BAg-36?
Cadmium-free Ag-Cu-Zn filler formulated as an improved-flow alternative in the 45% silver range, targeting applications previously served by cadmium-bearing alloys while meeting modern health and safety restrictions. BAg-36 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). BAg-36 has a yield strength of 220 MPa (31.9 ksi) and a tensile strength of 420 MPa (60.9 ksi) — stronger than 67% of precious metal grades. Elongation at break is 28% and the elastic modulus is 90 GPa (13.1 Msi).

Thermal5
BAg-36 is rated for continuous service to 200°C (392 °F). It conducts heat at 100 W/m·K (57.8 BTU/hr·ft·°F), better than 55% of precious metal grades. Thermal expansion is 18.5 µm/m·K (10.3 µin/in·°F).
Electrical3
BAg-36 conducts electricity at 21 % IACS, better than 57% of precious metal grades.
Chemical & Environmental3
Corrosion resistance is good (60/100), worse than 88% of precious metal grades.
Sustainability4
Producing a kilogram of BAg-36 takes about 900 MJ of energy and emits 65 kg of CO₂ — less than 80% of precious metal grades. Typical recycled content is 40%.
Manufacturability4
BAg-36's formability very good (75/100).

Working with BAg-36
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.
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 |
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 — frequently asked
What is BAg-36 used for?
BAg-36 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?
BAg-36 has a typical yield strength of 220 MPa (31.9 ksi) and a tensile strength of 420 MPa (60.9 ksi) — stronger than 67% of precious metal grades.
