The Constantan Perforated Metal contains 55% Cu and 45% Ni providing constant resistivity and large strain inclination at the various temperatures. It offers improved fatigue properties and high elongation ability.
Perforated metal is basically a sheet metal consists of perforated, embossed or slotted plates. It is basically made by puncturing the material by using a tool. The perforated metal is made of specific metal that has holes made by a die. On the base of kind of metal, the ratio of hole size to material is adjusted. We have professional and expert die and tool makers who perform the task quickly.
We offer the perforated metal in the following shapes: Circle, square, triangle, hex, oval and various other shapes. We utilize the latest tools to puncture the holes in the different shapes making the process more economical and spectacular.
