WIRON LIGHT, Nickel-Chromium Alloy for Crowns & Bridges

Wiron® Light is a top-quality nickel-chromium alloy specifically designed for crowns and bridges. With outstanding melting properties and a reduced preheating temperature, this alloy ensures simple casting, easy finishing, and reliable performance in dental restorations. Its light oxide color and smooth surface make it an ideal choice for efficient, high-quality dental work.

Key Benefits for Dental Technicians:

• Simple Casting and Easy Finishing: Wiron® Light's superior melting properties ensure reliable mould filling, while the lighter oxide color can be quickly and easily removed, streamlining the finishing process.
• Reduced Preheating Temperature: The alloy requires a lower preheating temperature of 800°C, resulting in a smoother cast surface, saving time in the finishing process and ensuring a high-quality finish.
• Time-Saving Ceramic Veneering: With its favorable CTE value (13.7 x 10ˉ⁶ Kˉ¹), Wiron® Light permits reliable and economical ceramic veneering, with normal cooling used for many ceramics.
• Biocompatible and Corrosion-Resistant: Thanks to its firmly-adhering passive layer, Wiron® Light is biocompatible and highly resistant to corrosion, making it safe and durable for patients.
