Description
Wiron® Light
The NON-precious alloy for metal-to-Ceramic work.
Advantages
Simple casting, easy finishing, reliable working
The outstanding melting properties of the alloy ensure reliable filling of the mould
The oxide of Wiron® Light is considerably lighter in colour in comparison to conventional NiCr Alloys and can be removed very quickly and easily
The reduced preheating temperature of 800°C means that a very smooth surface of the cast object is achieved
Normal cooling with many of the ceramics – for time-saving, economical veneering
The favorable CTE value permits reliable Ceramic veneering
Biocompatible and highly corrosion-resistant thanks to a firmly adhering passive layer
