What is Ag130?
EN ISO 17672 Ag130 (L-Ag30Sn, BAg30CuZnSn) is a lower-silver, cost-reduced cadmium-free Ag-Cu-Zn-Sn braze filler for general copper and brass joining where joint strength requirements are moderate. It brazes at about 755–790 °C and is available as rod, flux-coated rod, wire, strip, preforms, paste and powder, with as-brazed deposits of 410 MPa tensile strength, 25 % elongation and service to 200 °C. Zinc volatilisation limits time above liquidus and rules out vacuum furnace brazing. Ag145 or Ag134 are the alternatives when a lower brazing temperature or a stronger deposit is required. Ag130 has a density of 8.7 g/cm³ (0.314 lb/in³), lighter than 96% of precious metal grades. It melts at 665°C (1,229 °F). Ag130 has a yield strength of 250 MPa (36.3 ksi) and a tensile strength of 410 MPa (59.5 ksi) — stronger than 81% of precious metal grades. Elongation at break is 25% and the elastic modulus is 95 GPa (13.8 Msi).

Physical3
Ag130 has a density of 8.7 g/cm³ (0.314 lb/in³), lighter than 96% of precious metal grades. It melts at 665°C (1,229 °F).
Mechanical9
Ag130 has a yield strength of 250 MPa (36.3 ksi) and a tensile strength of 410 MPa (59.5 ksi) — stronger than 81% of precious metal grades. Elongation at break is 25% and the elastic modulus is 95 GPa (13.8 Msi).
Thermal6
Ag130 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
Ag130 conducts electricity at 19 % IACS, worse than 51% of precious metal grades.
Chemical & Environmental3
Corrosion resistance is good (55/100), worse than 94% of precious metal grades.
Sustainability4
Producing a kilogram of Ag130 takes about 480 MJ of energy and emits 36 kg of CO₂ — less than 95% of precious metal grades. Typical recycled content is 40%.
Manufacturability6
Ag130's machinability is fair (45/100, better than 59% of precious metal grades); weldability poor (15/100); formability very good (70/100).

Working with Ag130
Is Ag130 easy to machine?
Rarely machined; the deposit is soft and gummy — use sharp tools, positive rake and light cuts if a brazed fillet must be dressed.
Can Ag130 be welded?
Not a fusion-weld material; apply by torch, induction, resistance or furnace brazing at about 755–790 °C with FH10/FH11 boron-fluoride flux, keeping time above liquidus short to limit zinc volatilisation.
Can Ag130 be formed, bent or molded?
Supplied cast-then-drawn or rolled; the annealed alloy draws to fine wire and rolls to foil, and preform rings bend cold without cracking.
Ag130 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 |
|---|---|---|
| Agsilver content defines the designation Ag130 | 29 – 31 | 30 |
| Cu | 35 – 37 | 36 |
| Sndepresses melting range and improves flow, replaces Cd | 1.5 – 2.5 | 2 |
| Cdcadmium-free per EN ISO 17672; also RoHS Pb limit | ≤ 0.01 | — |

What surface finishes work on Ag130?
Post-braze flux residue must be removed by hot-water quench or dilute acid pickle; the fillet can be wire-brushed, polished or nickel/chrome plated, but it etches lighter than brass base metal.

Ag130 — frequently asked
What is Ag130 used for?
Ag130 is typically used for copper tubing, brass fittings, general sheet metal assemblies and appliance manufacturing. In short: cost-reduced 30 % silver filler; cadmium-free general-purpose BAg; copper and brass workhorse.

What is the maximum service temperature of Ag130?
Ag130 is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
How much does Ag130 cost?
