Values for the AS-BRAZED condition
What is BAg-13a AS-BRAZED?
BAg-13a AS-BRAZED is BAg-13a heat treated to AS-BRAZED — property set representing the solidified joint rather than the supplied filler stock. BAg-13a AS-BRAZED has a yield strength of 210 MPa (30.5 ksi) and a tensile strength of 400 MPa (58 ksi) — stronger than 61% of precious metal grades. Elongation at break is 22% and the elastic modulus is 95 GPa (13.8 Msi). BAg-13a AS-BRAZED has a density of 9.75 g/cm³ (0.352 lb/in³), lighter than 77% of precious metal grades. It melts at 771°C (1,420 °F).
Advantages

Working with BAg-13a AS-BRAZED
Is BAg-13a easy to machine?
Rarely machined; the soft Ag-Cu matrix is gummy — use sharp tools, high rake and light cuts if trimming preforms.
Can BAg-13a be welded?
Not a structural weld metal; joints are made by furnace, vacuum, hydrogen, induction or torch brazing at 900–980 °C with tight 0.05–0.13 mm clearance.
Can BAg-13a be formed, bent or molded?
Annealed stock draws to fine wire and rolls to 0.05 mm foil; interstage annealing needed because it work-hardens quickly.
What surface finishes work on BAg-13a?
Joints are normally left as-brazed; clean flux residues in hot water/acid, and passivate stainless assemblies afterwards — silver fillets tarnish in sulfur-bearing air.
BAg-13a 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 |
|---|---|---|
| Ag | 55 – 57 | 56 |
| Niimproves wetting of stainless steels and carbides | 1.5 – 2.5 | 2 |
| Cdcadmium-free grade; impurity limit | ≤ 0.01 | |
| Znzinc-free formulation; impurity limit for vacuum service | ≤ 0.5 | |
| Pimpurity limit | ≤ 0.01 | |
| Other (total)sum of unspecified elements | ≤ 0.15 | |
| Cu | balance |
BAg-13a AS-BRAZED — frequently asked
What is BAg-13a AS-BRAZED used for?
BAg-13a AS-BRAZED is typically used for vacuum furnace brazing, stainless steel structural joints and aerospace components. In short: zinc-free for vacuum brazing; highest braze range in family; stainless-specific Ag-Cu-Ni filler.
What is the yield strength of BAg-13a AS-BRAZED?
BAg-13a AS-BRAZED has a typical yield strength of 210 MPa (30.5 ksi) and a tensile strength of 400 MPa (58 ksi) — stronger than 61% of precious metal grades.
Is BAg-13a AS-BRAZED easy to machine?
Reasonably — machinability is rated good (55/100, better than 86% of precious metal grades). Rarely machined; the soft Ag-Cu matrix is gummy — use sharp tools, high rake and light cuts if trimming preforms.
Can BAg-13a AS-BRAZED be welded?
Not readily — weldability is rated poor (20/100). Not a structural weld metal; joints are made by furnace, vacuum, hydrogen, induction or torch brazing at 900–980 °C with tight 0.05–0.13 mm clearance.
What surface finishes work on BAg-13a AS-BRAZED?
Joints are normally left as-brazed; clean flux residues in hot water/acid, and passivate stainless assemblies afterwards — silver fillets tarnish in sulfur-bearing air.
Can BAg-13a AS-BRAZED be formed, bent or molded?
Annealed stock draws to fine wire and rolls to 0.05 mm foil; interstage annealing needed because it work-hardens quickly.
What is the maximum service temperature of BAg-13a AS-BRAZED?
BAg-13a AS-BRAZED is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
