| Purpose |
-
342 Casting Bronze is a bright yellow bronze
designed to cast jewellery samples, models, belt buckles, art objects,
etc.
-
It finishes to a bright 14K color and easily
solders with silver or low gold formulas.
-
#342 has a much better resistance to tarnish
than brass alloys, as well as a harder surface.
-
#342 also contains a silicon de-oxidizer for
clean casting.
|
| Melting |
-
Melt Temperature for casting 1050°C,
1922°F.
|
| Flask Temperature |
-
A high flask temperature for light and medium
weight pieces is recommended 1200° -
1300°F.
|
| Fluxing |
-
Boric Acid is the recommended flux.
-
Use as little flux as possible.
-
Do not use carbon fluxes or any fluxes designed
for refining; i.e. soda ash, saltpeter, etc.
-
Avoid flux in bottom pour automatic casting
units.

| Quench Time |
|
| Investment Removal |
-
Most standard investment removers will successfully
remove the investment powder. Fluoric-based investment removers are the
best for removing the silicon oxide invisible coating.
|
| Notes |
-
Melt temperature may vary with type of unit.
-
This grain is designed for casting only. #342
Bronze should not be used for gold casting!
-
#342 Bronze should not be cyanide gold plated,
use acid gold plating unless nickel subplate is used.
