Description

Metspec 117 is a low melting alloy that has a melting point of 117 °F (47 °C). It's mainly used in the optical industry for work holding where the lowest temperature possible is needed.It is also known as MCP 47. Here are some technical details about Metspec 117: *Short-term tensile strength lbs/sq.in.: 5400 *Yield temperature: 117 *Weight lbs/cu.in: 0.32 *Brinnell hardness no. (500 kg): 12 *Growth/shrinkage - time after casting: after 2 mi.: 0.0005, after 1 hour: -0.0001 *Contains: Bi, Pb, Sn, Cd Metspec 117 is used for: *Work holding: Mainly in the eyeglass industry *Lens blocking: In the optical industry *Tooling and production aids: It is an easily castable material that can be used as soon as it freezes Metspec 117 can be recovered and recycled into new uses a number of times. Low melting point alloys have a low temperature to melt. Alloys have a lower melting point than pure metal because they are solid solutions in which the lattice structure crystals contain atoms of another element within the lattice.
