Product Description

Product Functions and Advantages

The superior performance of Qihong stainless steel foil strip stems from our control over the entire process, from material selection to production and processing. We select high-quality stainless steels from the 200, 300, and 400 series. Commonly used foil strip models such as 304 and 316L are particularly popular with customers due to their wide range of applications. Our company uses advanced equipment; the foil strip undergoes a series of meticulous processes including cold rolling, annealing, and finishing to achieve thickness accuracy down to the micrometer, ensuring consistent dimensions for every batch.

This meticulous processing not only makes the foil strip highly flexible and easy to shape, handling complex stamping and cutting processes, but also results in exceptional surface smoothness and flatness, making it suitable for applications with high aesthetic requirements, such as electronic packaging and medical devices. Furthermore, stainless steel itself is not easily oxidized and is corrosion-resistant, ensuring our foil strip maintains stable performance even in harsh environments such as humidity and high temperatures.

Product Applications:

Thanks to its multifunctional properties, our stainless steel foil has been deeply integrated into multiple high-tech manufacturing fields, becoming an important basic material:

In the electronics industry, its high precision and good conductivity are widely used in electrodes, shielding covers, and battery tabs for microelectronic components. The corrosion resistance of 316L material solves the oxidation problem of electronic devices in humid environments. In the aerospace field, the foil, due to its lightweight and high strength advantages, is used in precision structural components and wiring fasteners inside aircraft, helping to reduce equipment weight while ensuring safety. In medical devices, non-toxic and easy-to-clean stainless steel foil is used to make surgical instrument accessories and sensor components for diagnostic equipment, meeting the stringent hygiene standards of the medical industry. In the production of new energy batteries, the foil, as a tab material, can reduce internal resistance, improve conductivity, and directly extend battery cycle life.
