Product Description

New Arrival: Super-thin R30003/R30008 Cold Rolled Foil for sensor and damper, minimum thickness 0.01mm


R30003/R30008 is is an austenitic alloy strengthened by cold work and capable of additional hardening by aging at a moderate temperature (around 500°C). In the fully hardened condition, its elastic modulus is around 210 000 MPa, with UTS levels up to 2500 MPa on cold rolled strip. In addition to its very high yield strength, PHYNOX offers a range of physical, chemical and technological properties that make it appropriate for a wide variety of applications. 


Xunshi is glad to announce that we could offer cold rolled R30003 foil of thickness down to 0.01mm and width 70mm. The foil could be used in application like sensor and damper. 


Phynox cold rolled strip is one of our main products and we have rich experience in the area. Our Phynox(2.4711) products are widely used in surgical implant industry, mobile phone, diaphragm valve, oil field monitor, spring seal,  spring energized seal, Variseal and spring.

  • Non-magnetic.
  • Ability to be used over a wide range of temperatures, from liquid helium to about 500°C.
  • Perfect passivity in contact with human tissues.
  • The possibility of increasing the strength of parts by age hardening after forming, leading to strength levels unattainable with other materials.
  • The absence of brittleness at low temperatures (no transition temperature).
  • A maximum service temperature about 100°C higher than for stainless steels.
  • A corrosion resistance vastly superior to that of molybdenum containing stainless steels.
  • A very high yield strength that combined with a high elastic modulus in both tension and torsion, enables the storage and rapid release of large amounts of elastic energy.
