Duckheung Special Ind. specializes in wire for interdental brushes. We supply two product lines — our proprietary DH-Wire and the high-tensile 302 HT — to interdental brush manufacturers worldwide.
DH-Wire — Proprietary Specialty Wire
A proprietary specialty wire developed by Duckheung Special Ind. in 2007 exclusively for interdental brushes. Not a standard steel grade — independently developed in-house using a proprietary stainless alloy. Features a high tensile strength of 1000 MPa and exceptional stiffness that resists bending.
