Nickel Base Non Precious Dental Alloys In Shot Shape Great Flexibility

Nickel Base Dental Casting Alloys for Crown and Bridge in Shot or Pellet


Our Pellet shape of Nickel base dental casting alloys enables to obtain smooth and compact surfaces and reduce the oxide formation. It has a strong resistance to traction and excellent workability. They are perfect economical alternative to Gold & Silver based alloys (precious) without compromising its performance thanks to Willett's mechanical properties and biocompatibility.


Advantages:


(1). Superior mechanical performance castability.

(2). Corrosion resistance, wear resistance, great flexibility.

FAQ:


What is the perfect temperature to obtain the best result when casting?


The casting temperature should always maintain 100~150℃ higher than liquidus temperature.


What is the perfect timing to obtain the best result when casting?


While casting Nickel Chrome alloys that don't contain Beryllium, the surface of the melting alloys will appear a layer of shadow. Once the shadow disappears and the edges of the alloy have become rounded (melted until it becomes a sphere shape is not necessary) will be the best timing for casting. Perfect timing for casting Cobalt Chrome alloy is to heat it till the surface membrane perforated and a spark of bright light start to appear.


Cobalt Chrome casting piece is incomplete, what are the causes?


1. Casting ring is not heated evenly: While casting Cobalt alloys, casting ring must heat up gradually and slowly before reaches 300℃. Let it sit in the oven in between 300℃ and 600℃ for 10-30 minutes. Once it heats up to the desired temperature, maintain the same temperature for at least 30 minutes before casting.


2. Casting temperature is below/above alloy's requirement.


3. Strub designed improperly: For example, Strub is too narrow. We strongly recommend the Strub diameter consist of 5mm or more.


4. The amount of alloy is not enough for the casting piece or the centrifugal force of casting pressure is not enough.


5. Casting piece has not avoided the heat center.
