Acti-4S Stainless Steel Archwire

All our Acti4S archwires are manufactured from 304VAR material. 304VAR is Vacuum Arc Remelted (VAR) stainless steel. This process yields a more uniform chemistry with minimal voids and contaminants. It would reduce any chances of brittleness that may l

True square or rectangular wire in cross section with minimum corner radii

All Acti4S wires are tested for required tensile strength before and after the archwire forming process

Strict inspection requirements for torque and arch form

The Acti4S material properties help us in getting true square or rectangular wire in cross section with minimum corner radii. The ease of joining Acti4S with solder or welding, combined with excellent strength makes it most desirable for orthodontic application. During Acti4S wire drawing, we insure that all our archwires are having minimum corner radii and are free of film on edges formed by carbide precipitation phenomenon that occurs if strict quality controls are not used during manufacturing process.

Tightest tolerance in size of Acti4S wire is maintained using continuous laser measuring equipment, which would automatically stop the production if the size variation were there. All Acti4S wires are tested for required tensile strength before and after the archwire forming process to ensure accurate tensile specifications. Various bend testing involving most intricate bends is performed on each lot to verify proper required ductility. Ready Acti4S archwires are then subjected to strict inspection requirements for torque and arch shape one by one. Each wire has to be perfectly flat not in front area but also in posterior sections. For we very well understand that torque is a serious condition that can cause harmful effects to an orthodontist's patient.
