Cerrobend Alloy

Cerrobend is a fusible, low-melting point alloy and that is most often used for thin-walled metal tube bending. Tubes and pipes can be bent to quite small radii without the risk of buckling or crimping when cerrobend is used as the filling material during the manufacturing process.

What is Cerrobend?

Cerrobend is a commercial/trade name for Wood’s metal. Also known as Lipowitz’s alloy, Wood’s metal is a eutectic alloy containing 50% bismuth, 26.7% led, 13.3% tin, and 10% cadmium by weight. Wood’s alloy is named for Barnabas Wood, the 19th century American inventor who first discovered the material.

In addition to pipe and tube bending, Wood’s metal/Cerrobend is commonly used as a low-melting point solder, a low-temperature casting metal, a high-temp coupling fluid in heat baths, and as a meltable valve element in commercial and industrial fire sprinkler systems.

Cerrobend Applications

In addition to the above-mentioned uses, other applications for Cerrobend include:

  • Custom apertures and blocks for medical radiation treatment
  • Metal inlays in wood
  • Die or mold material for repairing/refurbishing antiques
  • Adding weight to model railroad locomotives
