1. Product Composition and Interfacial Engineering
1.1 Core-Shell Framework and Bonding Device
(Copper-Coated Steel Fibers)
Copper-coated steel fibers (CCSF) are composite filaments consisting of a high-strength steel core enveloped by a conductive copper layer, developing a metallurgically bound core-shell architecture.
The steel core, generally low-carbon or stainless steel, offers mechanical effectiveness with tensile staminas surpassing 2000 MPa, while the copper layer– typically 2– 10% of the total diameter– conveys superb electrical and thermal conductivity.
The user interface in between steel and copper is essential for efficiency; it is engineered through electroplating, electroless deposition, or cladding processes to make certain solid attachment and marginal interdiffusion under operational tensions.
Electroplating is the most common method, supplying exact thickness control and consistent protection on continuous steel filaments attracted through copper sulfate bathrooms.
Correct surface pretreatment of the steel, consisting of cleansing, pickling, and activation, ensures optimum nucleation and bonding of copper crystals, protecting against delamination throughout subsequent processing or service.
With time and at raised temperature levels, interdiffusion can develop breakable iron-copper intermetallic phases at the interface, which may compromise versatility and long-term reliability– a difficulty reduced by diffusion barriers or rapid handling.
1.2 Physical and Functional Residence
CCSFs incorporate the most effective attributes of both basic steels: the high elastic modulus and tiredness resistance of steel with the remarkable conductivity and oxidation resistance of copper.
Electric conductivity commonly ranges from 15% to 40% of International Annealed Copper Requirement (IACS), depending on finish thickness and purity, making CCSF substantially extra conductive than pure steel fibers (
