SLT® Wire
works harder.

Expand

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, using SLT® wire will help streamline your production process.

Gain efficiency with SLT® wire.

We will provide Type 4 SLT® wire cut to length according to your specifications, straight, and ready for grinding. And since Type 4 SLT® wire will stay straight even after removing as much as 95 % of the cross-sectional area, you won’t even need to heat treat it. 

By replacing standard round wire in your process with Type 4 SLT® wire, the time savings can add up quickly. For example, processing 9 kg [20 lbs.] of 0.63 mm [0.025”] Type 4 SLT® wire can eliminate roughly 14 hours of processing time when compared to standard round wire.

Type 1

It eliminates manufacturing process steps, reduces set-up time, and often does away with the need for additional equipment. Typically used 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 has been used 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. Typical 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, which makes it a popular choice 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 often chosen for the most demanding applications.
