Elgiloy® wire is a premium cobalt-base alloy, specially-fabricated wire in four tempers. All tempers have the unique capability of beginning as a “softer” easily handled wire. This wire can be used as is, or heat-treated, providing flexibility and control in force applications. Wire forms made from Elgiloy® can be heat-treated, depending on the desired application. These wires are available in Penta-Morphic®, natural, ideal and blank arches as well as straight lengths (round, square and rectangular).
Blue – Blue Elgiloy is initially the softest of the tempers. It can be welded with low heat, and soldered without embrittling. Blue Elgiloy is recommended when the wire to be used is over .020” (0.508mm) or when the wire requires considerable bending, welding or soldering. Excellent for edgewise arches, lingual arches, retainers and removables.
Yellow – Yellow Elgiloy is initially ductile and slightly harder than Blue. Using caution, you can spot-weld and solder to large Yellow Elgiloy wires, .021” x .025”; .030”; .036” (0.533mm x 0.635mm; 0.762mm; 0.914mm), without embrittling them. Some practitioners use Yellow as furnished, but it can be heat-treated if greater resiliency or spring performance is required. After heat-treating, Yellow can be adjusted slightly, but should not be adjusted sharply. It is excellent for flat wire techniques. Yellow Elgiloy is recommended where greater spring qualities are needed, than those provided by Blue Elgiloy.
Green – Green Elgiloy is initially semi-resilient and will temper comparable to high spring-tempered steel wires. It can be shaped easily with the fingers and can be plier-manipulated before heat-treating.
Red – Red Elgiloy is initially “hard” with exceptionally high spring qualities. It is not recommended for heat-treating. Use where adjustments will not be required after
- Superior physical properties
- Longer functioning as a resilient spring wire without distortion or fatigue
- Easy soldering without annealing
- Easy heat-treating to increase physical properties
- Simple electrolyte polishing
