SLT® Wire
works harder.

SLT® Wire from Fort Wayne Metals has been engineered specifically to reduce production steps in your operation. Whether you just need basic wire that will eliminate the need for straightening and reduce machine downtime, a premium straightened wire that will not deform during deep taper grinding, or anything in between, SLT® Wire will outperform the standard round wire you’re currently using.

Type 1

It eliminates manufacturing process steps, reduces set-up time, and often does away with the need for additional equipment. That’s why we make Type 1 SLT® Wire. Ideal for staple wire, braiding mandrels, and dental probes, this ready to use product reduces setup time and eliminates the need to rotary or mechanically straighten before additional processes. Now you can streamline your process to get your product out the door faster without compromising quality.

Straightness variance 1.00 in. per 12.00 in. | 25.4 mm per 304.8 mm

Packing specifications Wire on a spool.

Min hub size 240x wire diameter | 220x wire diameter ≤ 0.030 in. / 0.762 mm

 

Type 2

Type 2 SLT® Wire significantly reduces process time by eliminating the need for mechanical straightening. This wire comes to you free of rotary marks, providing customer-ready surface without the need for later polishing. With no need to adjust for cast or helix in secondary processing, Type 2 SLT® Wire is ideal for mandrel wire, needle and staple wire, stylet wire, point coiling, and micro needle applications.

Straightness variance 0.118 in. per 12.00 in. | 2.997 mm per 304.8 mm

Packing specifications Wire on a spool or cut to length

Min hub size 220x wire diameter ≤ 0.030 in. / 0.762 mm

 

Type 3

Straightening and handling ultrafine wire can result in numerous problems such as rippling or pig tailing, but Type 3 SLT® Wire eliminates the need to straighten. In spring and hard conditions, this material is designed for removing up to 90 % cross-sectional area by taper grinding without requiring heat treatment. Applications for Type 3 SLT® Wire range from micro needles, orthodontics, and suture needles to guide wires, endoscopes and embolic filters.

Meets ASTM F2819 standards

Straightness variance 0.02 in. per 12.00 in. | 0.508 mm per 304.8 mm

Packing specifications Wire on a spool or cut to length.

Min hub size 400x wire diameter

 

Type 4

Our premier SLT® Wire features excellent 1:1 torque response, making it ideal for neurovascular guide wire, steerable PTCA, endoscopes, and other precision applications. Type 4 SLT® Wire is designed for deep taper grinding up to 95 percent without requiring additional heat treatment, regardless of condition. This superior grindability coupled with its kink resistance means this SLT® Wire is perfectly engineered for the most demanding applications. Type 4 SLT® Wire exhibits similar product characteristics to our legacy SLT® Ultrafine grind wire.

Meets ASTM F2819 standards

Straightness variance 0.01 in. per 12.00 in. | 0.254 mm per 304.8 mm

Packing specifications Cut to length only.
