RECOMMENDED USES .950 palladium is suitable for all general fabrication techniques. It can withstand high levels of deformation between anneals. This alloy does not require rhodium plating.

PROCESSING RECOMMENDATIONS

Working: For best results, G&S recommend 950 palladium is reduced by a Minimum of 50% area/section thickness between anneals.

Annealing: If using a furnace, anneal between 1650 - 1832°F (900 - 1000°C) for 15 – 30 minutes depending on size. If using as torch, heat to an orange color. This alloy can be quenched after annealing.

Investment Casting: Melting range: 2462 - 2516°F (1350 - 1380°C).
Casting temperature range: 2820 - 2910°F (1550 - 1600°C).
Flask temperature range: 1250 - 1350°F (675 - 730°C).
Investment type: Platinum (phosphate bonded).
Cover gas: Argon.

Tru-Pd must be cast using similar techniques to platinum alloys due to the high melting range of the alloy. Sprues and gates must be typical of those used for platinum castings.
Tru-Pd must be melted under an argon protective atmosphere to prevent gas absorption. It is recommended that induction casting equipment with a sealed melt chamber be used. Ideally the melt chamber should be vacuumed after loading the charge, and then back-filled with argon. If an open crucible is used; care must be taken to ensure complete cover with argon. While it may be possible to successfully cast Tru-Pd using a torch, results cannot be guaranteed. Temperatures may differ from these recommendations depending on processing considerations.

After casting, the flask may be quenched and de-vested once the button has returned to black heat.

Final de-vesting may use techniques standard to platinum alloy processing.

Soldering: Standard soldering techniques may be used with 950 palladium.

RECOMMENDED SOLDERS G&S palladium hard, medium and easy solder.
