The core of base materials is urgently needed: copper foil and aluminum foil support the "basic skeleton" of the industry
From signal transmission in electronic circuits, to energy carrying in power batteries, to protection and preservation in the packaging field, copper foil and aluminum foil have become indispensable "core substrates" for many industries such as electronics, new energy, and packaging due to their excellent electrical and thermal conductivity, ductility, and corrosion resistance. A high-quality copper foil and aluminum foil directly determines the performance stability, service life and safety factor of the end product. As a professional copper foil and aluminum foil manufacturer, Dongguan Hongyunda Electronic Materials Co., Ltd. is deeply involved in the field of metal foil materials. With "excellent quality, complete specifications, on-demand supply" as its core, it focuses on the research and development, production and sales of copper foil and aluminum foil. It provides highly adaptable substrate solutions for thousands of industries and helps industries achieve efficient upgrades.

Core Advantages: "Four Quality Highlights" of Hongyunda Foil Materials

Hongyunda Electronic Materials abandons the industry pain points of "insufficient precision, uneven performance and high loss rate" of traditional foil materials. Through raw material selection, process innovation and refined management and control, it has created a copper foil and aluminum foil product system with comprehensive performance, becoming the preferred partner for corporate procurement.

1. High-quality raw materials, stable and reliable performance

We insist on using high-purity electrolytic copper and high-quality aluminum alloy as raw materials. The copper content is ≥99.9%, and the aluminum purity can reach more than 99.5%, ensuring the basic performance of the foil from the source. After special rolling process, the conductivity of copper foil is ≥98% IACS, and the thermal conductivity of aluminum foil reaches more than 200W/(m·K). It has stable performance in extreme temperature environments (-60°C to 120°C) and is not brittle or oxidized. It is fully adapted to the needs of multiple scenarios such as electronic precision manufacturing and high-temperature industry.

2. Precision process control, precise and controllable specifications

Equipped with multiple high-precision rolling equipment and automated slitting systems to achieve precise control of foil thickness and width. The thickness of copper foil covers 0.006mm-0.2mm, and the thickness of aluminum foil ranges from 0.005mm-0.3mm. The thickness tolerance is controlled within ±0.001mm. The width can be customized according to needs, with a maximum width of 1600mm. The surface roughness Ra≤0.1μm ensures that the foil material is closely adhered and cut accurately in subsequent processing, reducing the production loss of the enterprise.

3. Multiple surface treatments to adapt to complex needs

It supports multiple surface treatments such as galvanizing, nickel plating, carbon coating, passivation, etc. to give the foil special functional properties. For example, the corrosion resistance of galvanized copper foil is increased by 3 times, making it suitable for electronic components in humid environments; the conductivity of carbon-coated aluminum foil is optimized to help power batteries improve charging and discharging efficiency; the oxidation resistance of passivated aluminum foil is enhanced, extending the shelf life of packaging products, and accurately matching the special use needs of different industries.

4. Environmentally friendly and compliant production, adapting to the green trend

Adhering to the concept of "green production", the production process adopts a circulating water treatment system and exhaust gas purification equipment to achieve zero emission of pollutants. All foil materials have passed SGS, RoHS and other environmental certifications and do not contain heavy metals and harmful chemicals. They can be directly used in food packaging, children's electronic products, medical equipment and other scenarios with extremely high environmental requirements, helping companies break through green trade barriers.
