Sapphire Ingots

High quality & High-purity sapphire ingots:

1. Finewin Wafers have 2 kinds of sapphire ingots: 80kg and 250 kg.

    The difference between 80 kg and 250 kg crystals is that 80 kg crystals use tungsten molybdenum thermal field, while 250 kg or larger crystals use graphite thermal field, 80 kg crystals are more consistent and more stable.

If for optical application, 80kg sapphire ingots are preferred.

2. Application：

- Sapphire ingots for LED production  

- Sapphire substrates for semiconductors  

- Sapphire ingots in aerospace components  

- Sapphire for watch crystals  

- Medical device sapphire ingots  

3. Orientation & Size
