MATERIALS

PRODUCING ANY TYPOLOGY OF SPRING

Raw materials for productions will be choosen considering solicitation they will have to handle and the environment.
Between wires we can select carbon steels according to these norms:
  • EN 10270-1 grade SL-SM-SH for static springs, grade DM-DH for low dinamic springs; circular or square cross-section.
  • EN 10270-2 grade FD-TD-VD: Cromium-Silicon alloyed steel for high dinamic springs.
  • EN 10270-3 stainless steel for various corrosive environment or high temperature. Grades 1.4310 NS-HS; 1.4568; 1.4401; 1.4301 NS-HS; 1.4539; 1.4462.
  • EN 12166 for copper, bronze and brass wire.
A lot of springs are made up of flat wire (especially due to settlement demands) that is obtained from circular cross-section wire, mainly starting with a EN 10270-1 or 10270-3 and bronze material. Flat wire can have smoothed or sharp edge.
Passing to tape we can use material according to these norms:
  • EN 10132-4 for carbon steel tapes.
  • EN 10151 for stainless steel tapes.
  • EN 1652 for copper, brass and bronze tapes.
Special materials can be used like Titanium, InconelĀ®, MonelĀ® and others.
