    solid state welding

    I'm looking for a method of welding two dissimilar wire materials (Nitinol & 304 SS) together. The wires are ranging in diameter from .030” to .005”. The problem with Nitinol and stainless joining is the forming of a brittle intermetallic compound TiFe. This is why I need solid state joining...

    cleanliness for ETFE coating

    I'm looking for a method of cleaning .004" MP35 wire to make it ready for coating with .001" thick ETFE. How can I clean the wire well enough to ensure that the draw oils and contaminants are removed, and also how can I quantify/measure this cleanliness? AR

    strong, flexible material?

    I'm looking for a non-metallic material that will deliver > 50% elongation at break and flex modulus > 800ksi. Is this possible to achieve with composites?

    Joining of dissimilar materials

    I need some input on how to join ø.016" stainless steel rod to ø.016" Nitinol rod (Nickel Titanium alloy) and achieve as strong a joint as possible. I am considering friction weld but I'm not sure if that will work on these diameters or these two materials. Any input would be...

    I am looking for a way of checking

    I am looking for a way of checking for good connections in a system where an insulated wire is put into a water bath for hipot testing. At present, I only know that I have voltage going into the wire if the wire is bad, creating a ground loop through the water. How can I measure if I have a...

    marking of PTFE

    I am presently looking for a method of applying a ring markerband on a wire that has been coated with a .0003" layer of PTFE. The PTFE used is dark green, and I need something that will adhere to the PTFE as well as giving a good color contrast. Minimal amount of increase in overall wire...
