Metal Twisting Apparatus (MC-1161)

This apparatus is used to compare the degree of brittleness of wires of different materials. Two pin chucks are mounted on stout metal brackets on a base board 240 x 100 mm. Brackets are positioned 100 mm apart. One of the brackets is fixed and other bracket rotatable by handle. The fixed chuck is drilled through to pass the wire under test for pretensioning purposes. The wire is slowly twisted until it breaks and the number of turns required to break samples of different metals noted and compared.

Supplied complete with a set of four wire samples.
