SLT® Wire
works harder.
SLT® wire
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. For more information, contact your Fort Wayne Metals Representative. If you want more information about handling our SLT® wire, visit our Video Library.
Type 1
Type 1 SLT® wire eliminates manufacturing process steps, reduces set-up time, and may eliminate 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 straighten before additional processes. Now you can streamline your process to get your product out the door faster without compromising quality.
Straightness variance 25.4 mm per 304.8 mm [1.00 in per 12.00 in]
Packing specifications Wire on a spool
Minimum hub size 220x wire diameter
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. 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 2.997 mm per 304.8 mm [0.118 in per 12.00 in]
Packing specifications Wire on a spool or cut to length
Minimum hub size 300x wire diameter
Type 3
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.
Straightness is measured using the test method described in ASTM F2819.
Straightness variance 0.508 mm per 304.8 mm [0.02 in per 12.00 in]
Packing specifications Wire on a spool or cut to length.
Minimum 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 removing in excess of 95% of cross-sectional area by taper grinding without rippling or pigtailing. No straightening or additional heat treatment is required, regardless of condition. This superior grindability and kink resistance means this SLT® wire is often chosen for the most demanding applications.
Straightness is measured using the test method described in ASTM F2819.
Straightness variance 0.254 mm per 304.8 mm [0.01 in per 12.00 in]
Packing specifications Cut to length only
Minimum hub size N/A
