Features of Jensen JYE Dental Noble Alloy Category: Crown & Bridge Nobility: Noble Color: Yellow Composition: 52% Au, 5% Pd, 24% Ag Ideal for: Demanding cases and everyday work SPRUING The indirect method is recommended for multi-units. Use an 8 gauge runner bar with 10 gauge connectors. If preferred, the direct method may be used on both single units and small bridges. Use a 10 gauge sprue 1/4” (6mm) to 3/8” (9mm) long. Sprues longer than 3/8” (9mm) should have a reservoir 1/16” (1.5mm) from pattern. Patterns should be a maximum of 1/4” (6mm) from top of investment. INVESTMENT AND Either gypsum or phosphate bonded investment may used following the BURNOUT manufacturer’s instructions. The burnout temperature should be at least 900ºF (480ºC) and should not exceed 1200ºF (650ºC). MELTING AND Extra winds of the casting arm are not required. A gas/compressed air or gas/oxygen CASTING flame with 5 psi gas and 10 psi oxygen is recommended. The alloy will fully puddle and form a ball before it is ready to cast. DO NOT OVERHEAT. The casting temperature is 1750ºF (950ºC). Bench cool to obtain the hardened condition. Water quench from a dull red heat to obtain the softened condition. DEVESTING AND Blast with aluminum oxide to remove investment particles and oxidation. Finish and FINISHING polish using standard techniques.
