Half round wire is another variation on the round cutting wire. Though rarely used, it is available in two (2) sizes and function much the same as the oval wire except that it has a better cutting action than the Oval Profile Wire.

Cutting Wire

Round cutting wire is often used as an inexpensive means of cutting of polymer films, these wires are available in sizes from 0.3 mm to 1.2mm both in rolls and made up into pre-cut lengths with, or without, copper plating at the ends. As with bands, best performance it is obtained with brass end connectors brazed to the ends. When cutting through two or more layers, the layers of film will be sealed with a very narrow seal along the edge.

Oval Profile Wire

The Oval Profile Wire, available in two (2) sizes is larger in cross section than the round Cutting Wire. It is most useful for making narrow seals on thick or stacked materials. It is not very effective as a cutting wire.
