LWD (Long Way of the Diamond), measured from the center of the joint to the
center of the adjacent joint. This dimension is built into the tool, and is always
parallel to the width of the coil and corresponds with the diamond dimension.
SWD (Short Way of the Diamond) is the length of the short axis way of the
diamond, measured from the center of the joint to the center of the joint.
For each fixed LWD dimension, there is a range of SWD dimensions available as
shown above.
Ductile Metals: Aluminum, Brass, Cadmium, Columbium, Copper, Gold, Inconel,
Lead, Magnesium, Nickel, Nickel Alloys, Phosphor Bronze, Platinum, Silver, Stainless
Steel, Low Carbon Steel, Tantalum, Titanium, Zinc, Zirconium, etc.
Plastics: Nylon, Polypropylene, Polyethylene, Mylar, Teflon, Tefzel, etc.
Explanation of Product Code:
Example: 3 Ni 5-077
First number represents nominal original thickness
3 = .003" (.076 mm)
Letters are chemical symbol for material
Ni = Nickel
Number immediately following letters represents strand width
5 = .005" (.127 mm)
Last number indicates the long way of the diamond
077 = .077" (1.96 mm)
