Silicon bronze wire is a high-end copper alloy wire made from copper-silicon alloy as the main substrate, with trace amounts of modified alloying elements. It undergoes multiple modern processes including high-temperature refining, impurity removal and purification, continuous drawing, precision annealing, and mirror polishing. This product differs from phosphor bronze and aluminum bronze wire, boasting four core characteristics: non-magnetic, high conductivity, oxidation resistance, and fatigue resistance. Its internal metallographic structure is dense and uniform, free from defects such as pores, sand holes, inclusions, and segregation. The wire has precise dimensions and a clean, bright surface. The product offers multiple mechanical states—soft, semi-hard, and fully hard—combining excellent flexibility and structural stability. It can meet the needs of various processes such as precision bending, stamping, welding, and precision assembly. It is widely applicable to industrial applications with extremely high requirements for conductivity, stability, and antimagnetism, such as electronics, electrical engineering, instrumentation, military explosion-proof equipment, and precision hardware. It is the preferred alloy wire for high-precision and high-stability applications.
1. Excellent Non-magnetic Interference Resistance: The silicon bronze alloy material itself has low magnetic permeability, resulting in non-magnetic and non-magnetic finished wires. This effectively avoids magnetic field interference, ensuring the testing and operational accuracy of precision electrical and instrumentation equipment. It is a dedicated material for explosion-proof and precision measurement and control equipment.
2. Stable Electrical and Thermal Conductivity: Compared to ordinary stainless steel and some bronze alloy wires, this product offers significantly superior electrical and thermal conductivity. It exhibits uniform and low resistance, generates no heat or voltage drop fluctuations during operation, and its electrical performance does not degrade over long-term use. It is suitable for manufacturing various precision conductive connectors.
3. Superior Oxidation and Corrosion Resistance: A dense and stable oxide protective layer can form on the wire surface, resisting oxidation at room temperature, humid air, and mild acid and alkali corrosion. It is resistant to blackening, rusting, and oxidation deterioration during long-term storage, exhibiting weather resistance far exceeding that of ordinary brass wires.
4. Excellent fatigue resistance and toughness, not easily broken: Scientifically formulated alloy with a high balance of hardness and toughness, it is not easily cracked or deformed under repeated bending, stretching, and vibration. It exhibits strong resistance to mechanical fatigue, making it suitable for elastic components and connecting parts operating at high frequencies for extended periods.
5. Extremely high process adaptability: The material has good plasticity, supporting various secondary processing methods such as cutting, straightening, bending, winding, stamping, resistance welding, and brazing. The processing is free of chipping, brittle fracture, and peeling, resulting in a high finished product qualification rate and suitability for automated mass production.
6. Highly consistent batch quality: Utilizing a fully automated melting and drawing production line with standardized control throughout the process, each batch of wire exhibits highly consistent composition, dimensions, mechanical properties, and electrical properties, with no batch differences, meeting the standardized requirements of high-end industrial applications.
1. Diameter Specifications: 2.0mm–20mm full range in stock, including ultra-fine precision filaments, standard industrial wires, and large-diameter solid wires. Custom processing of special non-standard sizes is supported.
