FUJI DIE
Fuji Die Fujiloy TR05/TR30 High Thermal Expansion Low Specific Gravity Hard Alloy
Manufacturer: Fuji Die Co., Ltd.
Model: TR05/TR30
Feature
- An innovative cermet alloy that combines a high coefficient of thermal expansion with excellent mirror-like finish.
- By bringing the coefficient of thermal expansion closer to that of glass, the jamming of glass material during mold release is suppressed.
- Mirror-like finish equivalent to binderless cemented carbide.
- Lightweight
- Corrosion-resistant
- Tungsten and cobalt free
Possible usage examples
- Mold for lens array
- Microfluidic molding die
- Infrared lens molding die
- Molds for special optical elements
- Mold for heat-resistant resin lenses
