Description

Lens Alloy 117 is a low-melting alloy used for blocking plastic and glass lenses during grinding operations. It has a melting temperature of 117°F (47°C). Lens Alloy 117 has the following properties: *Uses: Holds plastic and glass lenses during grinding operations *Blocking: Firmly blocks plastic lenses *Reusability: Reusable *Casting: Easily castable *Bonding: Provides a firm bond between the block and taped lens *Separation: Provides easy separation when surfacing and finishing Lens Alloy 117 is a bismuth-based eutectic low melting alloy. It can be recovered and recycled into new uses a number of times.
