Mount Joy Wire is an ISO 9001-certified high-carbon steel wire manufacturer specializing in a wide range of heat-treatment options under one roof, including annealing, patenting and oil tempering. We have over three decades of experience providing manufacturers and OEMs with customized wire solutions for demanding industrial applications. Mount Joy Wire maintains in-house material testing capabilities that verify performance characteristics and ensure consistent results. Mount Joy Wire is ready to deliver American-made precision and material consistency to your high-carbon steel wire and other wire manufacturing projects.
As a high-carbon steel wire manufacturer, our mission is to deliver precision specialty wire solutions with comprehensive heat-treat capabilities under one roof.

Bright, phosphated, and Galvanized Music wire and hard-drawn spring wire deliver exceptional tensile strength and fatigue resistance for aerospace, automotive, and industrial applications. Explore our available grades, diameter capabilities, and mechanical specifications.

Mount Joy Wire manufactures high-quality brush wire with precise temper control to balance stiffness and fatigue resistance. Browse available wire tempers and diameter ranges to meet your brush requirements.

We heat-treat and oil-quench this wire to lock in superior hardness and elasticity for high-impact spring applications requiring repeated cycling without deformation. Browse options that can conform to ASTM-A-229 Class I, Class II, or custom specs.

Chrome silicon alloy outperforms high carbon steel under high stress, shock, and extreme temperatures in demanding applications. Explore commercial-grade and 1% seam restricted options in bright, straw, or black finishes.

Annealing softens steel for forming applications through high- and low-carbon cycles, with high-carbon steel receiving full spheroidization treatment. View our annealed-at-finish or in-process annealing options.

High-tensile plow steel wire provides exceptional breaking strength and abrasion resistance in wire rope and cable assemblies used for lifting, hoisting, and structural applications. Request a quote for available grades and finish options.

Mount Joy Wire produces die-drawn and rolled shaped wire in rectangular, square, teardrop, and hexagonal cross-sections with rigid tolerances. Contact us for availability or to provide engineering drawings.

Custom wire is produced as fine as .002" in chemistries ranging from low carbon steel C1002 to high carbon C1095 plus chrome silicon 9254. Learn more specific shapes, fine sizes, and engineered solutions.
