(Originally published March 2017)
General Alloy Composition
96% silver, copper, germanium, grain refiners, and de-oxidizers
Suitable for
Casting
Melting Temperature Range
Solidus: 1,625°F (885°C)
Liquidus: 1,697°F (925°C)
Hardness (As-Cast) (HV)
57 HV
Hardness (70% Cold-Work) (HV)
N/A
Hardness (Age-Hardened) (HV)
• Two-step age hardness: Anneal the casting and quench after the red glow has disappeared; then heat the casting in an oven at 572°F (300°C) for a minimum of 1.5 hours. Remove from the oven and allow to air-cool to room temperature (125 HV).
• Single-step age hardness: Heat the as-cast piece at 572°F (300°C) for a minimum of 1.5 hours. Remove from the oven and either allow to air-cool to room temperature (105 HV) or allow to cool slowly inside the enclosed oven to room temperature (115 HV).
Available Forms
Casting grain
Fusing Possible
Yes
Welding Possible
Yes; use Argentium filler wire.
Quenching Guidelines
It is recommended that, after casting, the flask be left in the casting machine for 3 to 4 minutes before removing, then allowed to cool for 20 minutes in air before quenching.
Special Tips for Working with Alloy
- Argentium’s recommended flask and metal temperatures should be used as a guide.
- When torch melting, Argentium displays a paler glow in comparison to traditional sterling silvers when at the same temperature.
- When re-melting, use 50 percent new metal.
