# Tool Material Properties

The Tool material type is similar to the Solid material type and is a parameter used with the BEGIN MATERIAL data block. This material must be used when solving conjugate heat transfer problems. For Tool, HyperXtrude allows you to specify the conductivity in the form of diagonal tensor.
