The Ni-span- C902 Perforated Metal offerssmall thermo-elastic coefficient and excellent resistance to oxidation at the grand temperature levels. It can be processed to obtain stable modulus of elasticity at temperatures between 45oC to +65oC (-50oF to +150oF) and utilized in manufacturing weight determining machines.
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.
