Values for the AS-BRAZED condition
What is Ag130 AS-BRAZED?
Ag130 AS-BRAZED is Ag130 heat treated to AS-BRAZED — reference condition for joint design: lap-shear values on copper, brass and steel with 0.05–0.15 mm clearance. Ag130 AS-BRAZED has a yield strength of 250 MPa (36.3 ksi) and a tensile strength of 300 MPa (43.5 ksi) — stronger than 81% of precious metal grades. Elongation at break is 25% and the elastic modulus is 95 GPa (13.8 Msi). Ag130 AS-BRAZED 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).

Working with Ag130 AS-BRAZED
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.
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 AS-BRAZED — frequently asked
What is Ag130 AS-BRAZED used for?
Ag130 AS-BRAZED 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 yield strength of Ag130 AS-BRAZED?
Ag130 AS-BRAZED has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 300 MPa (43.5 ksi) — stronger than 81% of precious metal grades.
Is Ag130 AS-BRAZED easy to machine?
Reasonably — machinability is rated fair (45/100, better than 59% of precious metal grades). 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 AS-BRAZED be welded?
Not readily — weldability is rated poor (15/100). 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.
What surface finishes work on Ag130 AS-BRAZED?
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.
Can Ag130 AS-BRAZED 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.
What is the maximum service temperature of Ag130 AS-BRAZED?
Ag130 AS-BRAZED 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.
