1. Product Make-up and Interfacial Design
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 wrapped up by a conductive copper layer, creating a metallurgically bound core-shell style.
The steel core, typically low-carbon or stainless steel, provides mechanical toughness with tensile strengths exceeding 2000 MPa, while the copper coating– normally 2– 10% of the overall size– imparts exceptional electrical and thermal conductivity.
The interface between steel and copper is vital for performance; it is crafted through electroplating, electroless deposition, or cladding processes to make sure strong attachment and marginal interdiffusion under operational tensions.
Electroplating is one of the most typical approach, offering specific thickness control and consistent insurance coverage on continual steel filaments drawn with copper sulfate bathrooms.
Proper surface pretreatment of the steel, including cleaning, pickling, and activation, makes certain optimal nucleation and bonding of copper crystals, stopping delamination throughout subsequent handling or solution.
In time and at raised temperatures, interdiffusion can create weak iron-copper intermetallic phases at the interface, which may compromise flexibility and long-term dependability– a challenge minimized by diffusion barriers or fast handling.
1.2 Physical and Functional Characteristic
CCSFs incorporate the most effective qualities of both constituent metals: the high flexible modulus and fatigue resistance of steel with the remarkable conductivity and oxidation resistance of copper.
Electrical conductivity typically varies from 15% to 40% of International Annealed Copper Criterion (IACS), relying on finish density and pureness, making CCSF dramatically extra conductive than pure steel fibers (
