Ortho Spark Regular Stainless Steel Rectangular Wire

Stainless Steel arches are made from the quality vacuum-remelted 304V stainless steel alloy. This ensures a pure, inclusion-free arch wire, with superior tensile strength and less brittleness. All dimensions are closely monitored with state-of-the-art laser micrometers to ensure consistent and accurate tolerances. Strict corner-radius controls ensure optimal wire-to-bracket interaction. Wire torque is vigorously controlled, to prevent unwanted vertical discrepancies. All arches are carefully stress relieved and polished to reduce breakage and excess friction
